Thermal zeroing targets

[landowner]

Anyone know where I can buy decent thermal zeroing targets? Not passive ones, I can make those easily myself. I need a self-heating target. Do I have to short-circuit a AAA battery with a piece of wire again? I use the one-shot zero "freeze" feature on my XQ50/XP50 scope, which works well with two hotspots on the target -- one to aim at and the other to mark the hole. I spend ages filling out different zeroing profiles for different ammo, just want to save some time. I've made many of my own passive targets, using various cunning strategies, but I could save some time with some off-the-shelf self-heating targets.

yeah has chilly1981 says hand warmers are very good

As been said hand warmers but with this weather silver tape or use ice cubes which will be black in your scope but if you use black hot it  will be white in your scope look youtube

Use hot potatoes, when you need to fine tune use hot "peti poi's"

Thanks for the tips, just bought some hand-warmers, I'll give those a try.
