The best cross line lasers, compared.
Top pick: Bosch Professional Cross line Laser GCL 2-15 – Highest score in the set, with Class 2, ±0.3 mm/m, two plumb points, and an RM 1 mount, at 4.6 from 7,977 ratings. Daylight still hides the line. Best value: DOVOH Green Self Leveling Cross Line C2-120G – Score 90 at £49.99, with a rechargeable pack and pulse mode. The lower price among the three listings at that score. No printed mm/m figure. Updated October 2026.
A cross line laser projects a horizontal line and a vertical line, so you can mark level and plumb without holding a spirit level on the wall. They split into a single-wall cross, a cross with plumb dots, and heavier 360° kits. Judge a listing by the job, whether you will see the beam, a self-levelling window with a lock, a stated accuracy that names its unit, and the stand in the box. The [cross line laser buying guide](/hub/measuring-equipment/cross-line-laser/sub/cross-line-laser-buying-guide) follows that order. It does not print a millimetre-per-metre figure, and the receiver is not in the box. UK buyers are householders hanging pictures, shelves, and tiles, and trades who want a visible line across a room. A single cross, often a fan of about 110 degrees, suits one wall. A combi such as the 2-15 adds plumb points and an RM 1 mount, so you can transfer a point up or down. A 360 degree plane covers several walls from one setup.

Personal buying guide
Question 1 of 2
What are you marking?
The GCL 2-15 adds two centred plumb points to a red cross, with Class 2, IP54, and ±0.3 mm/m stated inside a ±4 degree window. The first 50 UK reviews, set against 4.6 from 7,977 ratings, describe downlights, floor-to-ceiling marks, tiling, studwork, and kitchen boxes, and one person could see the line at about 10 m in subdued light. The RM 1 rotating mount arrives with a target plate, three AA cells, a protective bag, and an L-BOXX inlay rather than a hard case. Strong daylight is the limit that keeps coming back: a UK review says there is no practical distance in bright light. One unit was returned because it dazzled and threw two horizontal lines, and another buyer said the bag was missing. Getting the mount stable takes some fiddling, so this is the top pick in the set for a stated millimetre-per-metre figure and plumb dots, not because we tested it in a lab.
Pros
Cons
Best for: Indoor fit-out that needs plumb dots and a stated ±0.3 mm/m, in subdued light.
Less suitable: Bright sun, or a buyer who only wants a green line for one wall of pictures.
Specifications
Common questions
What laser class does the listing state?
Class 2, with IP54, self-levelling within ±4 degrees, and accuracy ±0.3 mm/m.
Are plumb points included?
Yes. The listing states two centred plumb points as well as the horizontal and vertical lines.
Does the box include a hard case?
It includes a protective bag and an L-BOXX inlay, a target plate, the RM 1 mount, and 3× AA batteries.
This Huepar kit pairs a green 110 degree cross with a 35 cm to 100 cm aluminium tripod and a 1400 mAh pack stated at six hours, at £55.99. The listing prints an accuracy of ±1/9 inch at 33 feet, IP54, and self-levelling within 4 degrees, while the title says 30 m and another bullet says up to 100 feet. Against 4.5 from 8,119 ratings, reviewers say the line is easier to see than an older red laser and report use on floors, mirrors, and tiling, including a check against a digital inclinometer. The tripod is repeatedly called flimsy, the switch needs two clicks or the tool seems broken, and a lit garage hides the line beyond a short run. Some of the first 50 reviews describe 360 degree lines that these bullets do not claim, so those comments may belong to a different kit. A weak bracket is blamed for a dropped laser in one review, and no laser class is stated.
Pros
Cons
Best for: Indoor floors, mirrors, and tiling when you want a green cross and a 1 m stand in the box, and you will replace the stand if it flexes.
Less suitable: Daylight outside, or anyone who needs 360 degree planes this listing does not claim.
Specifications
Common questions
How tall is the included tripod?
35 cm to 100 cm, with a 1/4 inch quick-release plate. Reviewers call that stand flimsy.
What accuracy is printed?
±1/9 inch at 33 feet, a 110° cross, and self-levelling within 4 degrees. The title says 30 m.
Why might it not self-level?
A UK review says the switch must go two clicks. The bullets say the line blinks past 4 degrees.
The GLL 2-10 projects one red cross and, on the amazon.co.uk listing, levels itself within ±4 degrees in under four seconds, with a stated accuracy of ±0.3 mm/m and a range of up to 10 m. In 19 UK reviews, set against a listing line of 4.5 from 1,704 ratings, buyers say it agrees with a spirit level for pictures and rails and that it sets up in seconds. The same notes say the line is weak in daytime outdoors, and the box is three AA cells and a pouch, not a tripod. One buyer found the controls fiddly, and one unit stopped working after four months. At £89.95 it is a stated-accuracy red cross rather than a first cheap cube, and the English bullets do not print a laser class. A pendulum lock is not stated, so you should not assume a transport lock is part of this model.
Pros
Cons
Best for: Indoor pictures, rails, and a single wall where you want a stated ±0.3 mm/m and can bring your own stand.
Less suitable: Daytime outdoors, plumb-point work, or anyone who needs a tripod and a stated laser class in the box list.
Specifications
Common questions
What working range does the listing state?
The item type name states up to 10 m. UK reviews say the line is harder to see in daytime outdoors.
Does it include a tripod?
No. The listing includes the laser, 3× AA batteries, and a pouch.
What accuracy is stated?
The bullets state ±0.3 mm/m and self-levelling within ±4 degrees in under 4 seconds.
The DOVOH C2-120G is a green two-line cross at £49.99 with a built-in 2600 mAh pack, a stated eight-hour runtime, a magnetic bracket, and pulse mode. The listing says a 10 kHz receiver is not included, and the 60 m figure applies only with that receiver. In 39 UK reviews, against 4.5 from 286 ratings, people used it in a bright room, a bathroom, and a floor of about 6 m by 5 m, and they say the pack lasts a working day after a first charge of about five hours. Direct sun still hides the line. The bullets do not print a numeric accuracy, an IP rating, or a laser class. One unit died after about five months and would not charge, so this is the best value only if you can accept a missing millimetre-per-metre figure.
Pros
Cons
Best for: A rechargeable green cross near £50 for one room or one floor, if you can live without a printed mm/m figure.
Less suitable: Buyers who need plumb dots, a stated accuracy unit, or a receiver in the box.
Specifications
Common questions
Does pulse mode include a receiver?
No. The listing says a 10 kHz receiver is not included, and states 60 m with that receiver.
What battery is stated?
A built-in 3.7 V 2600 mAh pack, Type-C, with a stated 8 hours. The box includes the cable and a magnetic bracket.
When does the line blink?
Outside the ±4 degree self-levelling window. Manual mode locks the line at an angle.
At £18.69 the Nikotek cube is the cheapest green cross in this set, stated as Class II under 1 mW and IP54, and it runs on two AA cells with a bag and a 1/4 inch thread. The first 50 UK reviews, against 4.4 from 1,551 ratings, use it for mirrors, shelves, wallpaper, and blinds, and they call the line bright for the money. The box has no tripod and no magnetic bracket, so the height depends on a stand you already own. One buyer could not trust it on a stair rail, the base has to sit nearly level or the beam flashes past 4 degrees, and one laser stopped after six months. No numeric accuracy is printed. It is a first indoor line for occasional marks, and it is a poor substitute when the job needs a stated millimetre-per-metre figure.
Pros
Cons
Best for: Occasional indoor shelves, mirrors, and blinds if you already own a tripod.
Less suitable: A stated accuracy figure, a magnet in the box, or a stair rail you cannot check another way.
Specifications
Common questions
Is a tripod included?
No. The box is the laser, 2× AA batteries, a manual, and a bag. The 1/4 inch thread takes a tripod you already own.
What laser class is stated?
Class II, output under 1 mW, and IP54.
How do you know it is out of level?
The beam flashes past the 4 degree window. Locking the pendulum switches to manual mode.
The Huepar 703CG projects three green 360 degree planes, stated as Class 2 under 1 mW, accurate to ±3 mm at 10 m, and self-levelling within 3.5 degrees before the line flashes. The first 50 UK reviews, against 4.4 from 835 ratings, prefer those full-room lines to a cheap red cross, and they note a hard case, a magnetic bracket, and a 6600 mAh pack that arrived charged. Huepar replaced one unit that stopped within a month. Reviewers also call the housing plasticky, the magnets weak on some mounts, and the line a little thick, and direct sun still hides it. There is no tripod in the box, and one buyer was caught out by the thread even though the listing states both 1/4 inch and 5/8 inch. At £144.32 and 1.95 kg it covers a room from one setup, which is a different job from a single wall.
Pros
Cons
Best for: A whole room of lines from one setup, when you want a stated ±3 mm at 10 m and a hard case.
Less suitable: One wall of pictures, or outdoor sun without a receiver the listing does not mention.
Specifications
Common questions
Is this a single-wall cross or a 360° tool?
It is sold as a 3×360° green laser with a magnetic bracket and both 1/4 inch and 5/8 inch threads.
What accuracy and class are stated?
±3 mm at 10 m, Class 2 under 1 mW, and IP54.
Is a tripod in the box?
No. The box lists the laser, a hard case, a target plate, and a Type-C cable.
The GLL 20-22 G is the green Bosch listing here, titled for indoor use, with IP65 housing and an LB 10 bracket at £154.00. The English bullets state ±0.3 mm without saying per metre, and they do not state a working distance or a self-levelling window. The box includes two LR6 cells, a target plate, and a bag; a lithium-ion pack is described as an option and is not supplied. One short UK review calls the product good, against a listing line of 4.4 from 66 ratings. That review contains no criticism and no defect, which is too thin to treat as a pattern. The missing English range and the unclear accuracy unit are the reasons to pause before you treat this as a clearer version of the cheaper red Bosch tools.
Pros
Cons
Best for: An indoor green Bosch only if you already accept few written reviews and an accuracy figure that does not say per metre.
Less suitable: Anyone who needs an English working range, a large set of UK reviews, or a lower price.
Specifications
Common questions
Is a working range stated in English?
No. The English bullets state ±0.3 mm without per metre, and they do not state a distance. The title says indoor use.
What power sources does the listing allow?
A 3.7 V lithium-ion battery or AA cells via an adapter. The included cells are 2× 1.5 V LR6, not the lithium-ion pack.
What protection rating is stated?
IP65, with the LB 10 bracket, a target plate, and a protective bag.
The LV1 is the red RockSeed cross at £22.99, about 110 degrees, with IP54, two AA cells, a canvas case, and a 12-month warranty stated on the listing. Accuracy is printed as ±2.5 mm without per metre, which is not the same claim as ±0.3 mm/m. The first 50 reviews overlap the green LV1GT reviews, against 4.3 from 6,010 ratings, and they treat it as a low-price indoor line once the base is nearly level. Daylight makes the red line harder to see, the magnetic bracket is not included, and this box does not list a tripod even though the shared review pile talks about one. One overlapping review returned a unit as not accurate. Laser class is not stated, so this suits a dim room where you already own a stand, not a job that has to match the Bosch millimetre-per-metre figure.
Pros
Cons
Best for: A dim-room red cross at £22.99 when you already have a stand and do not need a millimetre-per-metre claim.
Less suitable: Daylight work, or any job where ±2.5 mm without a distance has to match ±0.3 mm/m.
Specifications
Common questions
Is the beam red or green?
This listing states a red cross at about 110°. The magnetic bracket is not included.
What accuracy is stated?
±2.5 mm, without per metre. Self-levelling is 4°±1°, and the line flashes outside that window.
What is in the box?
The LV1, a canvas case, and 2× AA batteries, with a 12-month warranty. A tripod is not listed.
The LV1GT title offers a green RockSeed cross at £29.99 with a short tripod, IP54, two AA cells, and a stated ±2.5 mm that does not say per metre. The what-you-get bullet omits the tripod the title names, one bullet mentions a red cross on a green title, and the self-levelling text says both 4 degrees ±1 and 110 degrees. The first 50 reviews largely match the red LV1 reviews, against 4.3 from 6,001 ratings, and they praise indoor brightness for shelves, tiling, and panelling. The same pile calls the stand flimsy or the screw too short, notes a stiff slider, and records one return after the unit failed against builders' lasers. One patio check is said to have matched a dearer site laser. Treat the box contents as unresolved until the parcel is in your hand.
Pros
Cons
Best for: A first indoor laser only after you confirm the tripod is actually in the parcel.
Less suitable: Anyone comparing accuracy units, or a job that needs a fine height adjuster.
Specifications
Common questions
Is the tripod definitely in the box?
The title says a 65.6 cm tripod. The what-you-get bullet lists the laser, a canvas case, 2× AA batteries, and a manual, and does not name the tripod.
What accuracy is stated?
±2.5 mm horizontal and ±2.5 mm vertical, without per metre. One bullet also says a red line on a green-beam title.
What is the self-levelling window?
The bullets state 4°±1° and, separately, a 110 degree tilt. Those figures conflict.
This Nikotek kit adds a 66 cm aluminium tripod to a green cross at £29.99, with IP54, two AA cells, a canvas bag, and a 1/4 inch thread. Both lines stay on together, and the bullets say there is no single-line mode. The first 50 UK reviews, against 4.3 from 5,312 ratings, call it bright indoors for panelling and cabinets, and they note the flash when the base is past about 4 degrees. The tripod is the complaint that repeats: too short and wobbly, with people moving the cube onto a camera tripod. Bright sun hides the line. One household thought the tool was faulty until support explained the pendulum lock, and no numeric accuracy is printed.
Pros
Cons
Best for: Panelling and cabinets where 66 cm is high enough and both lines on together is acceptable.
Less suitable: A ceiling line, single-line mode, or a stand you can trust not to wobble.
Specifications
Common questions
Can you switch to only a horizontal line?
No. The bullets say both lines project together and there is no single-line function.
How tall is the tripod?
66 cm aluminium. Reviews say it is too short and that a camera tripod is steadier.
What does a flashing line mean?
The tool is past the 4°±1° self-levelling range. Lock the pendulum for manual mode.
The Lusweimi kit is a green cross at £34.99 with a stated accuracy of ±3 mm over 10 metres, Class II, IP54, and a 127 cm tripod, the tallest stand in this set. The body is listed at about 170 g, it runs on two AA cells, and the box includes four cells plus a bag. Only two UK reviews are written up, against 4.2 from 92 ratings: one says it kept picture rows straight, and the second calls it a great tool before the reviewer had used it. Neither review answers outdoor use, and no defect is described. The warranty bullet states both one year and 24 months. With so few written reviews, the useful facts are the taller tripod and an accuracy figure that names a distance, not a long track record.
Pros
Cons
Best for: Picture rows where the 127 cm tripod is the point and a ±3 mm over 10 m claim is enough to start.
Less suitable: Anyone who wants a large set of written UK reviews or a single warranty length.
Specifications
Common questions
How tall is the tripod?
127 cm, also described as a 50 inch maximum, with a 1/4 inch-20 thread and a bubble on the stand.
What accuracy and class are stated?
±3 mm over 10 metres, Class II, and IP54. The laser body is stated at about 170 g.
How many batteries does it use?
Two AA cells run it. The box includes four, so two are spares, plus the bag and the tripod.
The SAVSEC SV-Y04CG throws two horizontal and two vertical green 360 degree planes, stated as Class 2 under 1 mW, self-levelling within ±3 degrees, with pulse mode and a 5200 mAh pack. Accuracy is printed as ±1/9 inch at 33 feet, and the kit weighs 2.57 kg. The box includes a remote, a magnetic bracket, a mini stand, green glasses, and a drop-proof case, not a full-height tripod and not a receiver. The first 50 UK reviews, against 4.1 from 105 ratings, praise indoor brightness and the accessory pile, and one DeWalt user preferred this unit. A remote failed for one buyer, the magnet is called weak, the lines are hard to see outside, and one battery would not charge. The glasses are a kit item, not certified protective eyewear, so this is a cheaper four-plane option than the Huepar 703CG with a thinner and less happy set of reviews.
Pros
Cons
Best for: Indoor multi-wall layout if you want four 360 degree planes under £80 and you will check the battery and remote on day one.
Less suitable: Outdoor lines, a full-height tripod, or anyone who would treat the kit glasses as safety eyewear.
Specifications
Common questions
How many planes does it project?
Two horizontal 360° lines and two vertical 360° lines, with brightness control and a remote.
What class and runtime are stated?
Class 2 under 1 mW and IP54. Runtime is stated as 6–37 hours depending on brightness, from a 5200 mAh pack.
Does outdoor use need anything else?
Pulse mode with a receiver is stated to extend the distance. The box list does not name a receiver. A review says the lines are hard to see outside.
Twelve amazon.co.uk cross line laser listings are on this page. Order follows the display scores: the Bosch GCL 2-15 first, then the DOVOH C2-120G as the lower price among the three listings that score 90, then the rest by score. The weights below follow the buying order in the digest and sum to 100. Stars, review counts, stated accuracy, class, range, and price were read from those listings. Review notes are the UK reviews read for each listing, not every rating. There was no laboratory test of brightness or accuracy. A printed Class 2 label is not proof the output is under 1 mW.
Coverage
25%Whether the listing is a single cross for one wall, a cross with plumb dots, or a 360° plane for several walls from one setup. A rotary laser is a different category.
Beam you can see
20%Green is sold as easier indoors than red. A brighter-beam claim is a manufacturer line. Direct sun hides both colours unless you have pulse mode and a receiver.
Self-levelling and lock
20%Most listings state a window near ±4°. Outside it, the line should flash. Manual mode locks the pendulum for an angle and for travel. A locked line is not level.
Stated accuracy
25%Only a figure with a clear unit counts. ±0.3 mm/m is not the same claim as ±2.5 mm with no distance, or ±0.3 mm that does not say per metre.
Power and stand
10%AA cells or a USB-C pack, and whether a tripod is in the box and tall enough. A 1/4 inch thread fits a camera tripod. Reviewers often call a 66 cm stand the weak part.
Start with the job, then whether you will see the line, then the lock, the accuracy unit, and the stand. Prices in this set run from £18.69 to £154.00 on amazon.co.uk. A 4.6 from 7,977 ratings is a larger sample than 4.4 from 66. Listing figures are maker claims. This page did not run a laboratory test.
A cross line laser projects a horizontal line and a vertical line so you can mark level and plumb without holding a spirit level on the wall. UK buyers are householders hanging pictures, shelves, and tiles, and trades who want a visible line across a room. A single cross, often a fan of about 110 degrees, suits one wall. A combi such as the Bosch GCL 2-15 adds plumb points and an RM 1 mount, so you can transfer a point up or down. A 360 degree plane covers several walls from one setup.
Manual mode locks the pendulum for the journey. An unlocked pendulum is free to swing in the case. A locked line on site is not a level line. Unlock it, let it settle, and mark only when the beam is steady.
A flash or a blink means the base is outside the self-levelling window, often about ±4°. The Huepar 703CG states 3.5°, and the SAVSEC states ±3°. Do not treat that line as level. Level the base, or move it, until the beam holds still.
±0.3 mm/m on the Bosch GLL 2-10 and GCL 2-15 is not ±2.5 mm with no distance on the RockSeed listings, and it is not ±0.3 mm on the GLL 20-22 G, which does not say per metre. A 66 cm tripod is also a poor stand for a ceiling line. Direct sun hides red and green.
A single cross, often about a 110° fan, suits one wall of pictures, shelves, or a splashback. The Bosch GLL 2-10 is that pattern in red, stated to 10 m at ±0.3 mm/m, with no tripod in the box. The Bosch GCL 2-15 adds two centred plumb points and an RM 1 mount when you also need to transfer a point up or down. A 360° plane is a different job. The Huepar 703CG throws three green planes from one setup, at £144.32.
Accuracy only counts when the unit is clear. ±0.3 mm/m on the Bosch GLL 2-10 and GCL 2-15 is a millimetre per metre. ±3 mm at 10 m on the Huepar 703CG, and ±3 mm over 10 m on the Lusweimi, name a distance. ±2.5 mm on both RockSeed listings does not say per metre, so it is not the same claim. The DOVOH, the Nikotek cube, and the Nikotek 66 cm kit do not print a number. The Bosch GLL 20-22 G states ±0.3 mm and does not say per metre, and the English bullets do not state a range.
Three typical situations, each with a recommendation from this comparison.
Pictures, shelves, or one splashback, often a green cross under about £50 if you can live without a printed mm/m figure. The DOVOH C2-120G is £49.99, with a 2600 mAh pack, pulse mode, and 4.5 from 286 ratings. The receiver and a tripod are not in the box.
Tiles or sockets where you do not want to move the tool at every corner. The Huepar 703CG throws three green 360° planes, stated at ±3 mm at 10 m and Class 2, at £144.32 and 1.95 kg. There is no tripod in the box, and direct sun still hides the line.
You want a stated class, a mm/m accuracy, and a mount. The Bosch GCL 2-15 states Class 2, ±0.3 mm/m, two plumb points, and an RM 1 mount, at £119.99 with 4.6 from 7,977 ratings. Screwfix listed a DeWalt DW088CG-XJ, outside this set, at £127.99 inc VAT.
The top pick is the Bosch Professional GCL 2-15 at £119.99. The listing states Class 2, IP54, ±0.3 mm/m, two centred plumb points, and an RM 1 mount, with 4.6 from 7,977 ratings. Strong daylight is the limit that keeps coming back, and the box is a bag and an L-BOXX inlay rather than a hard case. The best value is the DOVOH C2-120G at £49.99, a green cross with a 2600 mAh pack and pulse mode, at 4.5 from 286 ratings. It does not print a millimetre-per-metre figure, and the receiver is not included.
Bosch Professional Cross line Laser GCL 2-15
Highest score in the set, with Class 2, ±0.3 mm/m, two plumb points, and an RM 1 mount, at 4.6 from 7,977 ratings. Daylight still hides the line.
DOVOH Green Self Leveling Cross Line C2-120G
Score 90 at £49.99, with a rechargeable pack and pulse mode. The lower price among the three listings at that score. No printed mm/m figure.
