Expand your Infiray Mate thermal imaging attachment with the Infiray ILR-1200-2 Mate laser rangefinder.The battery life is up to 20 hours when used as a laser rangefinder. Optionally, the laser rangefinder can share its battery capacity with the models of the Infiray Mate thermal imaging attachment series. This reduces the runtime of the LRF to approximately 4 hours, but extends the runtime of your thermal imaging attachment by an additional 5 hours!
