Whatever your job, zeroing your thermal weapon sight to your weapon is a a top priority. There are a few zeroing options for your thermal weapon sight. Either a DIY (do it yourself) or a prefabricated zeroing target.

Some do it yourself methods you are probably familiar with are:


  • MRE heaters
  • Two 9V batteries
  • A small piece of No Power Tape
  • A paper with a hole cut out of it

While the DIY are helpful they are clunky, time-consuming and accuracy is a tough to read.

Introducing… IR.Tools patented Zeroing Thermal target. An easy, fast, accurate, shooting target that hands you a confident zeroing experience.

IR.Tools™ Zeroing Target:

  • Combines the benefits of MRE heaters, passive thermal film, and paper to produce a fast, easy and environmentally friendly zero target.
  • Shoot indoors/outdoors and in inclement weather.
  • Target is consistently accurate.

The table below summarizes each option.

Method Advantage Disadvantage Hint
Zero Targets

IndoorsCloudy day


 Plan ahead Use pasters to extend target life. In many situations target is effective even without heater.
MRE Heaters Distinct Hot Spot, Quick Rapidly growing Aim Point Have all weapons ready to zero so the aim point does not grow as fast
9V Batteries Distinct Hot Spot, Quick Growing aim point, waste Have all weapons ready to zero so the aim point does not grow as fast, do not use lithium or hazardous batteries
No Power Film Simple Somewhat dependent on environment Make sure the target backer is leaned back about 15 degrees
Paper with Hole Simple Difficult to see Seek out a spot where the thermal energy behind the hole is different from ambient
