I have a bushnell, not sure of the model. The button is so easy to push that it will kill a battery in no time. It was given to me because the guy who had it couldn't figure it out. I have to install the battery backwards and carry a small screw driver. When I get where I need it, I switch it. If not the thing will be dead.

I aught to contact them and see if there's a fix. Just setting the thing down wrong is all it takes.
