Some people are advocates of thermals for stalking...some less so...but we have been out using the new Guide IR517V Pro thermal spotter which has a 640x480 sensor, and 1280x920 display, providing twice the resolution of my previous device the Quantum XD50S and considerably better identification...
Bit of a small test video we made to show the difference between a good thermal like the Guide 518, and the range topping TiCam 750.
