What's this battery issue you speak of? This is the second one I've owned, never had or heard of battery issues. Interested to hear about it.
Well it sounds like you have a good one or you would know..
Many of the units will freeze up. Meaning, no reticle or display when the button is pushed. To get it to function again you have to pull the battery and then put it back and all is good gain till the next time. This seems like a low battery issue but it is not. I sent 3 back before I got one that didn't do it.
If I had the spare $$ I would buy it. I am sure my son would like to have it. Are you entertaning trades of any sort?
