The best Hand sirens, compared.
Top pick: Estink hand crank siren 120 dB Best value: SUDEG hand crank siren 110 dB – Lowest shelf price, about £27.99, and the lightest unit, with UK reviews that say it worked. Updated 20.10.2026.
A hand siren is a portable mechanical siren you sound by turning a crank, with no battery and no mains lead. Judge a crank by handle speed, a handle that stays open, and a decibel line that states a distance. It is a signal for a drill, a yard, or a power cut, not an accredited burglar alarm and not a one-hand personal attack alarm. A two-handed crank is the wrong object if you need one free hand. Do not sound one against an ear or in a small room. The [hand siren buying guide](/hub/burglar-protection/hand-siren/sub/hand-siren-buying-guide) sets out the decibel, the handle, and the weight before you choose. On amazon.co.uk it is usually a painted metal unit of about 1.0–1.6 kg that claims 110 dB or 120 dB. In the handheld type, one hand supports the body and the other turns the crank. D G, a UK sounder maker, describes that layout, with an optional finger trigger, and a separate tripod model.

Personal buying guide
Question 1 of 2
What do you need on the listing?
The Estink is the dearest listing in this set at £36.28, a 1.19 kg red metal crank that prints 120 dB with no distance. The range attribute is 1,320 feet, which the bullets also call a quarter of a mile, and that distance is not a decibel at 1 m. The star line is 5.0 from a single rating, and the listing has no review text, so there is no UK account of the handle, the loudness, or a fault. The bullets say it needs no power support and that the sound depends on hand speed. A metal housing is stated, and a folding crank is not. The extra cost over the cheaper listings buys a higher printed number and a sample of one.
Pros
Cons
Best for: You specifically want the 120 dB wording and you accept that one rating is not a test.
Less suitable: You want UK review text, a decibel at 1 m, or a lower price for the same kind of crank.
Specifications
Common questions
Does the Estink siren need batteries?
The bullets say it needs no power support. It is listed as manual winding.
Does 120 dB include a measuring distance?
Not on this listing. The range attribute is 1,320 feet, which the bullets also call a quarter of a mile. That range is not the same as a decibel at 1 metre.
How many written reviews are on the listing?
None. The star line is 5.0 from 1 rating, with no review text, so praise and complaints are not available.
The SUDEG hand crank siren is the lightest listing in this set at 1.03 kg and the lowest shelf price at £27.99. Six short UK reviews on the listing are the only all-British review text here: a live stage cue, a full day with children at a VE Day event, and brief notes that it worked. One of those reviews calls it small and terrible and says it was not as loud as expected, and another finds the war-siren tone annoying as well as useful. The bullets say there is no power supply and name a crank speed of 50–80 rpm, while separate attributes print 220 V, a range of 1,000 cm, and a floor mount. The 110 dB line does not state a distance. None of those six UK reviews describes a stripped gear or a broken handle, which is a small sample beside a listing that disagrees with itself.
Pros
Cons
Best for: You want the lightest crank in this set for a drill or a stage cue, and you will ignore the 220 V attribute.
Less suitable: You need a decibel stated at 1 m, or you will treat the voltage line as a real mains spec.
Specifications
Common questions
Does the SUDEG hand crank siren need batteries?
The bullets say it does not use a power supply. Batteries are not listed. A separate attribute line says 220 V, which conflicts with those bullets, so the voltage line is not a reliable spec.
Is it described as tool-free to set up?
Yes. The listing says it is easy to install and needs no tools, and that one person can operate it.
Does the listing say it is weatherproof?
No. Weather resistance is not stated.
The MYFULLY MY-0289 prints 110 ± 2 dB(A) at 1 m and 550 ± 20 Hz, both depending on hand speed, at £29.46 and 1.17 kg. The bullets include a folding handle and lever and a waist pack, which is the most complete carry kit in this set. The star line is 4.2 from 88 on the amazon.co.uk listing, and every written review shown is headed Canada or the United States, so that text is not UK opinion. Those reviews often describe a loud first use, then a folding crank that shuts while you turn it, stripped gears, or a side lever that snaps. The range line is 1,000 m in both the bullets and the attribute, which is a distance claim rather than the 1 m decibel. The waist pack is for carrying the siren, not for protecting your ears.
Pros
Cons
Best for: You want a 1 m decibel line, a folding crank, and a waist pack, and you will not treat overseas reviews as a UK survey.
Less suitable: You will only trust UK-written reviews, or you need a handle with no folding hinge.
Specifications
Common questions
Does the MYFULLY MY-0289 need batteries?
No. The bullets say it has no power support and runs by winding the handle.
Does the handle fold?
Yes. The bullets say the handle and lever fold, and that a waist pack is included.
Are the written reviews from the UK?
Not on this listing. The star line is 4.2 from 88 on amazon.co.uk, but every written review shown is headed Canada or the United States. Those reviews often mention stripped gears and a folding handle that fails.
The KATSU 990630 prints 110 ± 2 dB(A) at 1 m, at £28.99 and 1.6 kg, and the bullets say loudness depends on how fast you turn the handle. Across 28 reviews at 3.9, the two UK notes split: one calls the frequency what the buyer wanted, and one says it is not 110 dB loud. That second UK review calls the handle poor and temperamental, more plastic than expected, and not built to last. The bullets claim a 500 m diameter while an attribute says 400 m, and neither figure is a measured substitute for the 1 m decibel. It is the heaviest unit in this set. A review from Spain on the same listing, which is not a UK opinion, says a few fast turns are already tiring. Weather resistance is not stated.
Pros
Cons
Best for: You want a printed 110 dB(A) at 1 m and you can crank a 1.6 kg body despite the handle complaint.
Less suitable: You need a folding handle or a waist pack, or you want a light unit for more than a few hard turns.
Specifications
Common questions
Does the KATSU 990630 need batteries?
No. The listing says it is hand powered.
How is the 110 dB claim worded?
The bullets say 110 ± 2 dB(A) at 1 m, and that loudness depends on how fast you turn the handle. A UK review says it was not that loud.
What do the reviews say about the handle?
A UK review praises the tone and calls the handle poor, temperamental, and more plastic than expected. Other written reviews on the listing are from outside the UK.
The SENRISE HB11115 is a 1.2 kg green aluminium crank at £29.69 that prints 110 dB with no distance and no star line on the listing. The bullets say the handle folds and that a baffle changes intensity and rhythm as you change crank speed, and they say the alarm needs no batteries. The range attribute is 1,000 mm, which is 1 metre, and that figure clashes with any reading of this as a long-range siren. Nothing is listed in the box, and the warranty line says no. There is no review text to confirm the baffle or the folding crank. Rust and corrosion resistance is a seller claim in the bullets, not an IP rating.
Pros
Cons
Best for: You want a folding handle and a named baffle and you can accept a listing with no reviews.
Less suitable: You want a star line, a decibel at 1 m, or a stated carry pouch.
Specifications
Common questions
Does the SENRISE HB11115 need batteries?
The bullets say it generates the alarm without batteries, by cranking. The power attribute is simply No.
Can you change the sound?
The bullets say intensity and rhythm change with crank speed and a baffle. No decibel steps are given.
Is there a review score?
No star line and no review text are on the listing, so there is no rating to quote.
Five amazon.co.uk hand-crank listings were scored from the listing text and the review notes already collected. There is no lab test and no measured decibel. A hand crank is not scored as a BS EN 50131 burglar alarm or as a one-hand personal alarm. The five weights below sum to 100.
Amazon evidence
30%Star rating scaled from 5, then a sample add-on. None if there is no star line, a small add-on for one rating, more for 20–30 reviews, and a capped add-on when the star count is large but the written reviews are not from the UK.
Spec you can use
25%A decibel stated at 1 m scores above a bare 110 dB or 120 dB. Contradictory voltage, centimetre, or millimetre lines are deducted. A range of hundreds of metres is not scored as the same fact as the 1 m decibel.
Carry and mechanism
20%Weight under about 1.3 kg, a folding crank or a listed carry item, and no described breakage. A UK handle complaint, or stripped gears in the written reviews, is deducted.
Review sentiment
15%UK text counts more than overseas text. Overseas breakage is noted and is not treated as a UK survey.

Confirm you are buying a crank siren before you compare the paint. Megaphones, pressed air horns, 12 V wired horns, and 220 V wall sirens are different machines and were left out of this set. Then read the decibel only with its distance, check the handle and the weight, and read the star line with the sample size. Prices below are the figures printed on the five amazon.co.uk listings, not a live check on 19 October 2026.
A hand siren is a portable mechanical siren you sound by turning a crank. There is no battery and no mains lead. On amazon.co.uk it is usually a painted metal unit of about 1.0–1.6 kg that claims 110 dB or 120 dB. In the handheld type, one hand supports the body and the other turns the crank. D G Controls, a UK sounder maker, describes that layout, with an optional finger trigger, and a separate tripod model. Stand-mounted units are a different layout.
A title that says siren is not enough. Megaphones, pressed air horns, 12 V wired horns, and 220 V wall sirens were removed from this set because they are different machines.
A printed range of hundreds of metres, or 1,000 cm, or 1,000 mm, is not the same fact as a decibel at 1 m. The SUDEG 220 V line also clashes with bullets that say no supply.
A proper wail means cranking hard, and reviewers say you tire within a few turns. Do not sound it in a small room or against an ear. A night test in a terrace is a neighbour problem, not a product trial.
Read a decibel only with the distance printed beside it. In this set the KATSU 990630 and the MYFULLY MY-0289 state about 110 ± 2 dB(A) at 1 m, and both say loudness depends on how fast you turn the handle. The Estink states 120 dB with no distance. The SUDEG and the SENRISE state 110 dB with no distance. A higher number without a measuring point is an incomplete line, not proof of a louder siren. A range of hundreds of metres is a different claim.
The handle and the gearbox matter more than the paint. A metal shell is not a durable gearbox. The KATSU is aluminium alloy at 1.6 kg, the heaviest printed weight here. A UK review praises the tone and calls the handle poor, temperamental, and more plastic than expected. The MYFULLY is 1.17 kg, with a folding handle and a waist pack in the bullets.
Three typical situations, each with a recommendation from this comparison.
You need a loud tone with no electricity, and someone there to crank. The MYFULLY MY-0289 states 110 ± 2 dB(A) at 1 m, a folding handle, and a waist pack. Written reviews on that listing are from Canada and the United States, not a UK survey.
You want one short event cue and the lightest crank in this set. The SUDEG is 1.03 kg at about £27.99. Six UK reviews say it worked. One calls it small and not as loud as expected, and a 220 V attribute clashes with the no-supply bullets.
You want 110 ± 2 dB(A) at 1 m and you can crank 1.6 kg. The KATSU 990630 prints that line and is hand powered. A UK review praises the tone and calls the handle poor, temperamental, and more plastic than expected.
The top pick is the MYFULLY MY-0289, score 73, at about £29.46. It states 110 ± 2 dB(A) at 1 m, a folding handle, and a waist pack. The written reviews on the listing are from Canada and the United States and often describe stripped gears, so they are not a UK survey. The best value is the SUDEG, score 70, at about £27.99 and 1.03 kg, the lowest price whose UK reviews say it worked. Its 110 dB line has no distance, and a 220 V attribute clashes with the no-supply bullets. Neither badge is a lab win.
