I just acquired a Zeiss Varipoint 2.5-10 x 42 with a number 60 reticle? Can anyone tell me the easiest way to change the battery?

The cap on the illumination turret just spins off. You may need a penny to assist. Be gentle so you don't strip the threads, unscrew, insert a 2032 battery, screw the cover back on and you should be in business...

That's what I do on my two.

Thanks Ghostrider! I knew it had to be something simple, but completely overlooked the end cap.
