      4.0 It's pretty much the only choice.


      Strong Construction,Compact



      This is pretty much the only choice for reticle eyepieces and for finder scopes. And it is only available here. I did purchase another brand a while back that had a flashing feature but it was big, bulky, and broke after first use.

      It would be nice for these things to turn off automatically after a few hours of non use. I just can't seem to remember to turn them off and I'm always replacing batteries.

      Bottom Line: Would you recommend this item? Yes
      Was this review helpful? Yes / No
