HornBlasters' Drill Horn, also sold by some dealers as the Handcannon Drill Horn, is the closest thing on the market to what we build: a handheld, battery-powered train horn with a trigger and a wireless remote. Here's how it compares, spec by spec, with a horn that runs on the cordless tool batteries you already own, and which one fits your use.
What the HornBlasters Drill Horn actually is
On its own product page, HornBlasters describes the Drill Horn (part number EH-DH) as two metal horns in a stealth-black finish on a cordless-drill-style body with a high-output direct-drive compressor. It ships fully preassembled with a wireless remote, a rechargeable battery, and a charger. The listed specs:
- Loudness: "around 125 dB up close," per the HornBlasters FAQ
- Battery: 21V lithium-ion pack and charger included
- Battery life: 750 honks per charge
- Remote range: up to 100 yards (300 ft)
- Modes: momentary (tap) or continuous (hold)
- Size: 12 in. tall, 12 in. long, 6 in. wide
- Warranty: 1-year manufacturer's defect warranty
Price depends on where you look. HornBlasters lists the Drill Horn at $179.99 on its own site. At least one dealer sells the same part number under the "Handcannon Drill Horn" name for $279.99. Same part number, same specs, so check the HornBlasters price before you pay a dealer markup.
That's a solid package. It's a real metal-trumpet horn, not a plastic noisemaker, and HornBlasters is upfront that you shouldn't honk it next to someone's ears or inside an enclosed space. The question is whether its numbers line up with what you actually need.
Spec-by-spec: Drill Horn vs a tool-battery train horn
Here's the HornBlasters Drill Horn next to our three main tiers, using the Milwaukee® M18™-compatible versions as the example. The same tiers exist for other battery platforms. All figures come from each seller's own product pages.
| Spec | HornBlasters Drill Horn | Dual (2026) | Quad | Extreme Series |
|---|---|---|---|---|
| Rated loudness | ~125 dB "up close" | 130 dB | 140 dB | 150 dB |
| Trumpets | 2 metal | 2 metal | 4 metal | 4 upgraded metal |
| Battery | 21V pack, included | Any M18™ pack you own (sold separately) | ||
| Included remote range | 100 yd (300 ft) | 300 ft | 160 ft | 160 ft |
| Long-range remote option | Not listed | Up to 2,000 ft ($59 add-on) | ||
| Price (black finish) | $179.99 (HornBlasters site) | $210 | $245 | $365 |
Two things jump out. First, the HornBlasters horn is the cheapest way into a handheld horn that comes with a battery in the box. Second, it's a two-trumpet horn rated below even our entry tier. The real decision isn't "which brand." It's how loud you need to be and whether you already own the batteries.
Loudness: what 125 dB vs 130, 140 and 150 dB really means
Decibels are logarithmic, so small-looking gaps are bigger than they seem. The Federal Highway Administration's noise guidance gives the rules of thumb: a 10 dB increase is perceived as roughly twice as loud, a 5 dB change is "readily perceptible," and a 3 dB change is barely noticeable. Using those rules on the rated numbers:
- 125 vs 130 dB (Dual): a 5 dB gap. You'll clearly hear the difference side by side.
- 125 vs 140 dB (Quad): a 15 dB gap, close to three times as loud to the ear.
- 125 vs 150 dB (Extreme): a 25 dB gap, roughly five to six times as loud.
One honest caveat: none of these ratings come with a published test distance. HornBlasters says "up close," and our tier ratings are also manufacturer figures. Distance matters a lot. FHWA's point-source rule says sound drops about 6 dB every time you double your distance. So treat the numbers as tier labels, not lab results. For the full math, see our breakdown of how the decibel scale works across dual, quad, and extreme horns.
Any of these horns is loud enough to hurt hearing at close range. The National Institute on Deafness and Other Communication Disorders lists sirens at 110-129 dBA and notes that the louder a sound is, the less time it takes to cause noise-induced hearing loss. Point the bell away from people. That goes double for the 140 and 150 dB tiers.
Battery: an included 21V pack vs the batteries you already own
This is the biggest practical difference. The HornBlasters Drill Horn comes with its own 21V lithium-ion battery and charger. That's convenient if you don't own cordless tools. Its listing doesn't say the pack is compatible with any cordless tool platform, though. A spare or replacement battery means going back to HornBlasters for one.
Our horns go the other way. Each model is built to accept a specific tool-battery platform, so the packs already sitting on your shop shelf or in your truck toolbox run the horn. That has a few knock-on effects:
- Spares are everywhere. If you already have three or four packs, you already have a deep reserve for a long tailgate or a day on the water.
- Charging is already handled. The charger in your garage works. If you need one, we sell an M18™-compatible 6Ah battery and charger for $30 each.
- Bigger pack, longer session. A higher-Ah pack gives you more blasts. Our guide to battery Ah and runtime covers how capacity translates to blasts.
HornBlasters rates its battery at 750 honks per charge, which is plenty for most outings. Our listings describe runtime as all-day use on a single charge rather than as a honk count, so we won't put a made-up number next to theirs. If you're unsure which platform to buy into, our comparison of Milwaukee® M18™ vs DeWalt® 20V MAX™ packs for a train horn walks through it.
Remote range: 100 yards vs 300 ft vs 2,000 ft
HornBlasters' remote reaches up to 100 yards, which is 300 ft. That matches the 300 ft remote that ships with our 2026 Dual model. Our Quad and Extreme Series include a 160 ft remote as standard.
Where the two approaches split is the upgrade path. HornBlasters doesn't list a longer-range remote for the Drill Horn. On our side, the Long-Range Remote (2,000 ft) pairs with our kits and pushes the range to about four-tenths of a mile. That matters for farm use, large properties, boat-to-shore signaling, or setting a horn on a truck bed and triggering it from across a campground. Our 300 ft vs 2,000 ft remote comparison covers when the longer range is worth it.
Which one should you buy?
The HornBlasters Drill Horn makes sense if you don't own any cordless tool batteries, you want everything in one box for about $180, and around 125 dB from two trumpets is loud enough for you. Think pranks, parking-lot fun, or a backyard gag.
A tool-battery horn makes more sense if you already own packs from a major platform, you want a louder tier, or you need more than 300 ft of remote range. Our Dual 2026 lands near the Drill Horn on price and remote range, rated 5 dB louder. The Quad adds two more trumpets and a fuller chord. If you want the most volume you can carry in one hand, the Extreme Series Train Horn for Milwaukee® 18v Battery is our flagship 150 dB model, with upgraded trumpets and a high-output compressor.

FAQ
Is the HornBlasters Handcannon the same as the Drill Horn?
Yes, as far as the listings show. The dealer "Handcannon Drill Horn" listing uses the same part number (EH-DH) and the same specs as the Drill Horn on HornBlasters' own site: dual metal horns, a 21V battery and charger, a 100-yard remote, and a 1-year warranty. The prices differ: $179.99 direct vs $279.99 at the dealer we checked.
Can I use a Milwaukee® or DeWalt® battery in the HornBlasters Drill Horn?
HornBlasters' listing only mentions its included 21V lithium-ion battery and charger. It doesn't list compatibility with any tool-battery platform. If you want to run your existing packs, choose a horn built for that platform.
Is a 150 dB horn too loud for everyday use?
It's more horn than a parking-lot prank needs, and it can damage hearing up close. It earns its keep where distance matters: farms, boats, off-road convoys, and large properties. For casual use, a 130 dB dual is plenty.
Do your horns come with a battery?
No. They're designed around batteries you already own, so the pack is sold separately. If you need one, we offer compatible 6Ah batteries and chargers as add-ons.
