The best digital spirit levels, compared.
Top pick: SAVSEC DL01 rechargeable digital angle finder Best value: Mecurate 15.7-inch digital level and angle finder – A spanning bar with a stated ±0.1° band, mm/m, and 553 ratings at about £35.99, below the dearer bars. Flip-check the zero. Updated October 2026.
A digital spirit level on amazon.co.uk is a bar with an electronic module, a pocket inclinometer for a saw blade or a small face, or a light-up torpedo that turns green and does not show degrees. You use one for shelves, saw setup, pipe and steel, and a slope you want in millimetres per metre rather than a guessed bubble. Quality is a stated error band, a body long enough for the job, and a zero you have checked by turning the tool 180°. Stabila publishes ±0.5 mm/m for the vials on the 196 DL and ±0.05° for the electronics at 0° and 90°, about 0.87 mm per metre by arithmetic. The [digital spirit level buying guide](/hub/measuring-equipment/digital-spirit-level/sub/digital-spirit-level-buying-guide) sorts bar, box, and light-up before a name. A DIY level is not legal for trade and does not approve Regulations work. Prexiso is 175 mm. eSynic is a 383 mm folding finder stated at ±0.5°. Franklin is a 12-inch light with no degree readout.

Personal buying guide
Question 1 of 2
Where will you seat the tool?
The SAVSEC DL01 is £24.99 with 4.9 from 29 ratings. Bullets state ±0.1°, units in degrees, percent, mm/m, and in/ft, magnets on the base and back, a zero, hold, and about four hours from a 30-minute charge. The title says IP54. A technical line says one C cell, which conflicts with the rechargeable bullet. All 29 UK reviews are in the saved listing. Buyers use it on saws and shelves. There is no repeated dead-on-arrival cluster. The star line is high and the sample is small.
Pros
Cons
Best for: A rechargeable box with mm/m if you can live with 29 ratings.
Less suitable: Anyone who wants Trend’s review volume, or a long bar.
Specifications
Common questions
What accuracy is stated?
The bullet says ±0.1° across four 90° ranges. It does not state a separate resolution.
How is it powered?
The bullets describe a built-in rechargeable pack and USB-C. Another line says one C cell. Those statements conflict.
Does it show mm/m?
Yes. The bullet lists degrees, percent, mm/m, and inches per foot.
The Grettz G-GL120 is a 1,200 mm level at £155.99 with 4.8 from six ratings. Bullets state under 0.1° at 0°, 45°, and 90°, under 0.2° otherwise, dual backlit screens, rare-earth magnets, IP65, and two AAA cells. The listing weight is 2.1 kg, with a carry case. All six UK reviews are positive about length and readability, and one calls the price high. There is no defect theme and no large sample. The tight angle claim is the listing text, not a test we ran. Six ratings do not make it a proven site tool.
Pros
Cons
Best for: A long digital bar when the run is about 1.2 m and you accept six reviews.
Less suitable: A proven site standard. Six ratings is not that evidence.
Specifications
Common questions
How long and how heavy is it?
1,200 mm and 2.1 kg on the listing. Dimensions are 120 by 6.5 cm.
What accuracy is stated?
Under 0.1° at 0°, 45°, and 90°, and under 0.2° at other angles.
What is the IP rating?
IP65 in the bullets. Do not read that as permission to immerse the level.
The Trend DLB is a pocket inclinometer at £19.95 with 4.7 from 5,486 amazon.co.uk ratings and rank 1 in Inclinometers in the saved listing. The bullets describe a rotating display, arrow icons, and zeroing on a saw table before the magnetic base goes on the blade. They do not state a degree accuracy. In the first 50 UK reviews, buyers use it on mitre saws, table saws, and roof pitch. One review says 0.1° steps are coarse for a perfect mitre, and one unit drained cells while switched off and was replaced. The listing weight is 170 g. That is the top pick here because of the rating volume for a numeric box, not because of a lab test.
Pros
Cons
Best for: Setting a mitre or table-saw angle when you want the deepest UK rating line in this set.
Less suitable: Spanning a worktop, or anyone who needs a stated degree accuracy on the amazon.co.uk bullets.
Specifications
Common questions
What accuracy does the amazon.co.uk listing state?
The bullets do not state a degree accuracy. A UK review says the screen shows angles to 0.1°. Treat that as a review, not a Trend specification on this listing.
Is it a long spirit level?
No. It is a small level box. The listing dimensions field says 28 by 28 mm and the weight field says 170 g.
Does the box include a laser?
No. Included components list the level box. Reviews describe a battery, not a laser.
The Franklin Sensors light level is a 12-inch plastic torpedo at £24.58 with 4.6 from 2,418 ratings and rank 5 in Levels in the saved listing. The lamps turn green at level or plumb, with two vials and a magnetic edge. The bullets do not state a degree accuracy, and they say the AA cell is not included. In the first 50 UK reviews, buyers praise the lamp when they cannot see a bubble. They also report missing batteries, flicker after drops, and a lamp that did not match the vial. One review says it drifted and cannot be recalibrated.
Pros
Cons
Best for: Solo fixing and dark corners when you need a glance, not a recorded angle.
Less suitable: Falls in mm/m, saw blades, or any job that needs a number.
Specifications
Common questions
Does it show degrees?
No. It lights green at level or plumb and has two bubble vials. The listing states no degree, percent, or mm/m figure.
Is a battery included?
The bullets say one AA cell is required and not included. Several UK reviews say the paperwork claimed a battery that was not in the box.
How long is it?
The highlight says 12 inches. The listing dimensions are 30.5 by 5.1 cm, and the weight is 177 g.
The Mecurate is a 15.7-inch digital bar at £35.99 with 4.5 from 553 ratings. The highlight states ±0.1° at 0° and 90°, ±0.2° elsewhere, 0.05° resolution, a magnetic V-groove, IP54, a beep, and four units. The box lists two AAA cells and a case. In the first 50 UK reviews, buyers like the numbers and the magnet, and several say they bought it instead of a dearer Bosch. Others report a factory zero that was out, digits that disagree with the vial, and one unit about 5 mm out after two months. It is the best value among the bars here because it is the spanning tool with hundreds of ratings, below the Huepar at £59.99 and the Grettz at £155.99. That is a price-and-evidence judgement, not a lab award.
Pros
Cons
Best for: A spanning digital level for DIY if you will flip-check the zero before you trust it.
Less suitable: Anyone who needs 600 mm or 1,200 mm, or a saw-blade cube.
Specifications
Common questions
How long is it?
The title says 15.7 inches. The listing length is 39.9 cm. The width field repeats 39.9 cm, so do not treat that as a 40 cm wide body.
What accuracy is stated?
The highlight says ±0.1° at 0° and 90°, ±0.2° at other angles, and 0.05° resolution.
Are batteries included?
Included components list two AAA cells and a carrying case.
The Prexiso PTD180 is a 175 mm, 200 g torpedo at £29.99 with 4.5 from 261 ratings. Bullets state ±0.1° from 0° to 90°, ±0.2° at other angles, units including mm/m, a V-groove magnet, a beep, and relative mode. Only six UK reviews are in the saved listing. They call it fine for home DIY. One says the battery cover needs a tiny screwdriver, and another taped the cover because it would not stay on. A review says two AAA cells and that the manual’s calibration makes the vial and the digits agree.
Pros
Cons
Best for: Pipe and short faces when you want mm/m without a 400 mm bar.
Less suitable: A full-length wall, or a four-side saw magnet.
Specifications
Common questions
How long is it?
175 mm. The listing dimensions are 17.5 by 4.8 cm and the weight is 200 g.
Can it show millimetres per metre?
Yes. The bullet lists degrees, mm/m, percent, and inches per foot.
Does it have a laser?
No laser is stated. It has a V-groove magnetic base.
The eSynic WT504 is £23.53 with 4.4 from 202 ratings. Bullets state ±0.2° and 0.1° resolution on the single axis over 4×90°, and ±0.3° on the dual axis over ±40°, with degrees, percent, and mm/m. The laser is a horizontal and cross line with no class stated. A UK review says it is not self-levelling and is for shade. Another buyer compared the inclinometer with a Stabila electronic level and called the angles spot on. The body is 11.8 cm and 115 g, with a 400 mAh USB-C pack.
Pros
Cons
Best for: A small dual-axis readout with mm/m, used indoors.
Less suitable: Daylight laser layout, or a long level.
Specifications
Common questions
What accuracy is stated?
Single axis ±0.2° at 0.1° resolution. Dual axis ±0.3° at 0.1° over ±40°.
Is the laser Class 2?
The bullets do not state a class. Do not assume Class 2. A UK review says the laser is not self-levelling.
Which units does it show?
Degrees, percent, and mm/m.
The Proster box is £28.99 with 4.4 from 25 ratings. Bullets state ±0.1° at 0° and 90°, ±0.2° elsewhere, 0.05° resolution, four-side magnets, absolute and relative zero, a Class 2 dual laser under 1 mW to IEC 60825, IP54, and a 340 mAh USB-C pack with auto-off after 3 minutes. Eleven UK reviews praise the screen and call the lasers dim in brighter light. Buttons can switch the tool on inside a pouch. Weight on the listing is 120 g.
Pros
Cons
Best for: A stated-accuracy laser box for indoor saw and shelf work.
Less suitable: Daylight layout, or buyers who want thousands of ratings.
Specifications
Common questions
What laser class is stated?
IEC 60825, Class 2, under 1 mW. Reviews say the line is weak in brighter light.
What accuracy is stated?
±0.1° at 0° and 90°, ±0.2° on the rest of the 4×90° range, resolution 0.05°.
Does it switch itself off?
The bullets say auto shutdown after 3 minutes.
The eSynic ST99G is £25.93 with 4.3 from 29 ratings. Bullets state ±0.5° accuracy, 0.1° resolution, a 0–225° arm, two vials, a 383 mm printed scale, a backlight, and a 9 V cell. The included-components list puts the battery in the box; another line says batteries are not included. Ten UK reviews like the metal body. One review title says it is not a digital spirit level. One says the lock nut does not lock the arm. Keep it as a folding protractor, not as a long digital bar.
Pros
Cons
Best for: Copying an angle and marking a short length with one tool.
Less suitable: Anyone who wanted a 600 mm electronic spirit level.
Specifications
Common questions
Is this a 600 mm digital spirit level?
No. It is a folding angle finder with a 383 mm scale, two vials, and a stated accuracy of ±0.5°.
What battery does it take?
A 9 V cell. The included-components list includes one. A technical line says batteries are not included, so the two lines conflict.
Does the arm lock?
The bullet describes a mechanical lock. One UK review says the lock nut does not hold the arm.
The XUNTOP XOP007 is £22.99 with 4.2 from 3,340 ratings and rank 2 in Inclinometers. The bullets state a Class 2 dual laser, four-side magnets, IP54, and a 340 mAh USB-C pack. They do not state a degree accuracy. In the first 50 UK reviews, people use it for kitchens and pipes, and they also say the tenths jump, the reading changes if you replace the tool, and the laser is weak. One buyer reports a failed tenth digit and no warranty reply. The laser is not described as self-levelling.
Pros
Cons
Best for: An indoor laser box if you can wait for the digits to settle.
Less suitable: A stated accuracy, a long straight edge, or daylight layout.
Specifications
Common questions
What laser class is stated?
The bullet says Class 2. It does not say the laser is self-levelling.
What accuracy is stated?
The bullets do not state a degree accuracy or a resolution.
How is it powered?
An internal 340 mAh battery charged by USB-C. The listing weight is 160 g.
The Huepar DL24 is titled as a 600 mm / 24-inch digital level at £59.99 with 3.9 from 21 ratings. Bullets state ±0.1° at 0° and 90°, ±0.2° elsewhere, 0.05° resolution, a magnetic base, four units, a beep, and IP54. The material field says ABS while the bullets say aluminium alloy. The dimension field says 60 by 60 cm, which repeats the length into the width. Ten UK reviews praise the beep and also include a shuttering buyer who found the digits way off, and a fabric case rather than a hard case. Battery chemistry is not stated.
Pros
Cons
Best for: A 600 mm digital bar if you accept a 21-rating sample and check the zero.
Less suitable: Buyers who want hundreds of UK reviews on a bar, or a hard case matching the photos.
Specifications
Common questions
How long is it?
The title says 600 mm / 24 inches. The listing dimension field says 60 by 60 cm, so the width figure is not a reliable second measurement.
What accuracy is stated?
±0.1° at 0° and 90°, ±0.2° at other angles, resolution 0.05°.
What is the IP rating?
IP54, in the bullets.
The Qivine is £15.99 with 3.6 from 45 ratings, the weakest star line in the set. Bullets state ±0.2° over 4×90°, four-side magnets, USB-C, hold, and auto-off after 30 seconds. The title says dual laser and does not state a class. The colour field says grey and a bullet mentions red. In 25 UK reviews, some buyers like it after a YouTube calibration, and others report units that will not switch on, a second failure a month later, and a laser with about 5 mm of runout.
Pros
Cons
Best for: A spare cube only if you can test power and zero on day one.
Less suitable: A first-choice level. Reviews include units that never powered on.
Specifications
Common questions
What accuracy is stated?
±0.2° over 4×90°. The bullets do not state a finer resolution.
Is the laser Class 2?
The title says dual laser. The bullets do not state a class. Do not assume Class 2.
Why is it not the best value?
The listing is 3.6 from 45 ratings, and UK reviews include units that did not power on. The Mecurate bar has 4.5 from 553 ratings at £35.99.
Twelve amazon.co.uk digital spirit level listings are on this page. Order follows the display awards first, then the display score. The weights below follow the buying order in the digest and sum to 100. Body, the stated error band, units, magnets, sealing, laser class where a listing states one, stars, review counts, and the shelf price were read from those listings and from the public UK sources below. There was no laboratory test. A 4.8 from six ratings does not outrank a 4.7 from 5,486.
Body and length
30%A pocket box, a short torpedo, a light-up level, a folding finder, or a bar of about 400 mm, 600 mm, or 1,200 mm. A short box cannot span a worktop. A long bar is the wrong tool on a mitre blade.
Stated accuracy
25%The error band printed on the listing, often ±0.1° at level and plumb and ±0.2° elsewhere, or a flat ±0.2°. Resolution is the screen step, not that band. A blank cell means the bullets used here state no degree figure.
Units and zero
20%Degrees, percent, mm/m, and in/ft, and whether you can set a relative zero. Absolute mode asks whether the face is level. Do not assume every bar has a zero button. Check it by turning the tool 180°.
Magnet, power, sealing, laser
15%A magnet needs steel. A V-groove is for pipe. No listing states pull force. USB-C or cells, IP54 or IP65 where stated, and Class 2 only where the listing says so. IP65 is not immersion.
Review evidence and price
10%Stars and the review count on the amazon.co.uk listing, then the shelf price in this set, from about £15.99 to about £155.99. A high star line from a handful of ratings is a thinner sample.
Match the body to the job, then read the stated error band, then the units and the zero. Prices in this set run from about £15.99 to about £155.99 on amazon.co.uk. A 4.8 from six ratings is a thinner sample than 5,486. Resolution is the screen step, not the error band. This page did not run a laboratory test.
A digital spirit level is a bar with an electronic module, a pocket inclinometer, or a light-up torpedo. In this amazon.co.uk set the bars are the Mecurate at 39.9 cm (£35.99), the Huepar DL24 titled 600 mm (£59.99), and the Grettz at 1,200 mm (£155.99). The boxes are Trend DLB, XUNTOP, Proster, SAVSEC DL01, Qivine, and eSynic WT504. Prexiso PTD180 is 175 mm. eSynic ST99G is a 383 mm folding finder stated at ±0.5°. Franklin is a 12-inch light with no degree readout.
A pocket box samples a small face. It does not represent a worktop, a long pipe, or a 2.4 m run. Use a bar whose length matches the job. Over 2.4 m, 0.1° is about 4.2 mm of rise, by arithmetic.
A 0.05° or 0.1° screen step is how fine the digits move. The error band is the claim beside it, often ±0.1° at level and plumb and ±0.2° elsewhere. Trend’s amazon.co.uk bullets state no degree figure at all.
Turn the tool around on the same spot on day one. If the two readings do not agree, do not fit to that number. Mecurate reviews include a factory zero that was out and digits that disagree with the vial.
Start with the face you will seat the tool on. A mitre blade or a saw table is a pocket box. The Trend DLB is that box, at about £19.95, with 4.7 from 5,486 ratings, a magnetic base, and no degree accuracy on the amazon.co.uk bullets. SAVSEC DL01 is another box, at £24.99, with a stated ±0.1°, mm/m, and only 29 ratings. XUNTOP, Proster, eSynic WT504, and Qivine also mention a laser. Franklin is a 12-inch light and shows no degrees. A shelf, a carcass, or a short fall needs a bar.
The figure that matters is the error band the listing prints, not the screen step. Huepar, the Mecurate highlight, Proster, and Prexiso state ±0.1° at level and plumb and ±0.2° elsewhere. SAVSEC states ±0.1°. Qivine states ±0.2°. eSynic WT504 states ±0.2° on one axis and ±0.3° on two. eSynic ST99G states ±0.5°. Grettz states under 0.1° at 0°, 45°, and 90°. Trend, XUNTOP, and Franklin state no degree figure on the bullets used here.
Three typical situations, each with a recommendation from this comparison.
You want a magnetic box you can zero on the saw table, and the deepest numeric-box rating line in this set. The Trend DLB is £19.95 with 4.7 from 5,486 ratings. The bullets do not state a degree accuracy, and the listing size is a pocket box.
You want a bar that can sit along a shelf or a short carcass, with mm/m and hundreds of ratings. The Mecurate is about 400 mm at £35.99, with 4.5 from 553 ratings and a stated ±0.1° at 0° and 90°. Flip-check the zero before you trust it.
You want mm/m and a V-groove on a face shorter than a 400 mm bar. The Prexiso PTD180 is 175 mm at £29.99, with 4.5 from 261 ratings and a stated ±0.1° from 0° to 90°. It will not represent a long pipe run.
The top pick is the Trend DLB at about £19.95. It is 4.7 from 5,486 ratings, a magnetic pocket box used on saws in UK reviews, and the bullets do not state a degree accuracy. The best value is the Mecurate bar at about £35.99, with a stated ±0.1° at level and plumb, mm/m, a case, and 4.5 from 553 ratings, below the Huepar at £59.99 and the Grettz at £155.99. Reviews include a zero that was out. Neither award is a laboratory test.
Mecurate 15.7-inch digital level and angle finder
A spanning bar with a stated ±0.1° band, mm/m, and 553 ratings at about £35.99, below the dearer bars. Flip-check the zero.
