Heated Target vs. Flare Target: Cost Per Session Compared

A flare thermal target costs $4.51 to $9.03 every time you light it, and each flare burns for only 15 to 30 minutes. A heated target that burns solid fuel or runs on a battery costs a fraction of that per session and holds its heat signature for hours instead of minutes. Over a season of thermal practice, the fuel bill is where the real price difference between these systems shows up, not the sticker on the unit.

How the cost per session breaks down

Here is the math for a four-hour afternoon of thermal shooting, using published flare pricing and our own fuel numbers:

1. Flare system. Each pyrotechnic flare burns 15 to 30 minutes. To keep a target hot for four hours you burn 8 to 16 flares. At $4.51 to $9.03 per flare, that afternoon costs $36 to $144 in fuel alone. Flares ship only in cases of $325 to $375, classified as hazardous material and non-returnable.

2. Solid-fuel firebox. The DRX1 Solid Fuel Thermal Optic Target burns retail charcoal briquettes, the same bag you would grab for a barbecue. A DRX1 fuel pack runs about $29.99, and one load burns roughly 4 hours (estimated; final burn-test data is still being closed out). One load, one afternoon, no re-stoking.

3. Electric. The DRX1 Electric Thermal Optic Target has no fuel cost at all. One charge on the big battery runs 5 hours at 100 watts. Recharge from dead is about 6 hours. Your cost per session is a wall outlet.

*Burn duration is an engineering estimate pending final test data. For context, LaRue's non-heated premium moving target sells at $2,799, so the $2,800–$3,000 flare units sit at the top of the market before you buy a single flare.

Why flares burn out so fast

A flare is a pyrotechnic: it dumps all of its energy in one short, uncontrolled burn. That is great for signaling and bad for a training session. It also burns hot enough to damage things. In our July 2 field test, a standard 20-minute road flare heated a plate visibly at 100 yards, but it also burned straight through the prototype's sheet-metal enclosure. That test is why the production firebox is built from 1/4" steel with a proper flare mount, and it is a fair warning about what open pyrotechnics do to thin metal.

Uncontrolled heat is also a steel problem. AR500 starts to lose its hardness if it gets too hot, which means ricochet and spalling risk. The X1 design puts a calculated air gap between the heat source and the plate so the steel stays below the annealing threshold, with a hard ceiling under 200°C by design. The plate stays hard for its whole service life. If you want the background on why steel needs added heat at all, read why steel targets are invisible to thermal.

What buyers actually say about the price

The flare-unit price bracket is $2,800 to $3,000, and buyers in this market already anchor against premium steel. One buyer on a UK stalking forum put it plainly: "When you see the price of 'Hardox targets' elsewhere it's a no brainer." Another described the purchase trigger that closed him on the spot: "the owner said £150 and if you shoot through it I'll give you your money back I couldn't leave it there?"

The lesson from both quotes is the same. People pay for heated steel when the durability is guaranteed and the ongoing cost makes sense. A system that charges you up to $9 every 15 to 30 minutes fails that second test the first time you run a full-day session.

Which heated target should you pick instead?

• DRX1 Solid Fuel Thermal Optic Target — the direct flare-system alternative. No electronics, no batteries, no controls, same as the flare units. The difference is the fuel: retail briquettes from any store instead of HAZMAT flare cases. One load holds heat for hours, unattended, with no re-stoking. It bolts to the upper mounting holes of an unmodified IPSC silhouette, 66% or 100%, no drilling, one person, no tools. Built for short-range sport and training sessions: handgun, PCC, rifle.

• DRX1 Electric Thermal Optic Target — the temperature-controlled flagship. Dial the signature anywhere up to ~100°C, hold it steady for 5 hours on the big battery, and recharge overnight. It out-glows a human at 300 m, is unmistakable at 400 m, and is visible at 600 m, which is why the long-range and sniper-training story belongs to the Electric. Proven outdoors at −10°C drawing only 30 watts.

FAQ

What fuel does the Firebox burn? Do I have to buy special stuff?

Regular charcoal briquettes, the same bag you would grab for a barbecue, from any retail store. Compare that to flare systems, where every heat cycle burns a proprietary flare at $4.51 to $9.03 a session, sold only in $325+ HAZMAT cases that are non-returnable.

Is it safe? Open heat on a range sounds sketchy.

The firebox is passively regulated by design with a hard ceiling under 200°C, even if a component fails. There is no open flare flame and no molten drips. Standard rules apply: outdoor use only, since burning briquettes produce carbon monoxide, and the box is hot during operation.

Won't heating the steel ruin it? AR500 softens with heat.

That is exactly why both X1 systems are engineered with a hard ceiling below 200°C under any condition. AR500 does not start tempering until well past that (~232°C), so the plate keeps its hardness for its entire life. There is no setting or fuel load that lets the target exceed it.

How long does the battery last on the electric model?

Five hours on a charge — 5 hours at 100 watts holds a 66% IPSC plate at 100°C. It ships with the big battery only, and recharge from dead is about six hours. At −10°C the target held a clear signature drawing only 30 watts, so cold weather does not gut the runtime.

Can I use the steel targets I already own?

Yes. The Firebox bolts to the existing upper mounting holes of an unmodified IPSC silhouette, both 66% and 100%. No drilling, no cutting, no tools, one person. It works with T-post and chain mounting and does not block your stand bracket.

What's shipping like? Anything restricted?

The Firebox has nothing restricted — no HAZMAT, no lithium, no flares. It ships like any steel target and you buy fuel locally. The DRX1 Electric Thermal Optic Target ships with a lithium battery under the same standard small-parcel rules as laptops and power tools, with no special permits on your end. Flare cases, by contrast, are HAZMAT-restricted and non-returnable.
