My general rule of thumb on novelty stuff like this is button cell batteries = Cracker Jack box-worthy.
I got these from woot awhile ago. They were stolen by my date who uses the heck out of them on the kayak or canoe.
I watched her giggle with them at Crater Lake this summer when she was watching a Condor and some bald eagles.
The button cell is only for the digital compas so it has to be replaced about once a year.
At an alpine lake she shot 3 directional bearings so we could find our tent in the woods from the lake.
