Whatever your job, zeroing your thermal weapon sight to your weapon is a top priority. There are a few zeroing options for your thermal weapon sight.

  • DIY (do it yourself) 
  • Ready-made 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 tough to read.

Ready-made zeroing is easy and accurate

Method Advantage Disadvantage Hint
Ready-made Zeroing Targets

Indoors, Outdoors, Cloudy day, Ready to shoot in minutes, Increased accuracy

 Upfront cost The use of thermal pasters will extend target life. Outdoor training the target works without a heater. The heater is recommended for indoors and on cloudy days.
MRE Heaters Distinct Hot Spot, Quick Blooming Aim Point, limited time for shots Have all weapons ready to zero so the aim point does not grow as fast
9V Batteries Distinct Hot Spot, Quick Blooming aim point, limited time for shots 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 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
