Guy, check with your Cardiologist on hunting at alititude. In addition to my heart attack I picked up a permanent case of AFIB. Tried all sorts of ways to get rid of it to no avail. I asked the Doc about hunting in elevation and he stated "keep it below 6000 feet. No more SCUBA diving either. I believe the AFIB is what's causing me the major problem over elevation but for your own safety check with the Doc.
I saw an old post where you recommended an ATN night scope.
I'm looking to get into the night life . The last time I looked through a night vision it was 1968/69 in Vietnam. Was called a "Starlight Scope" Big, bulky and real heavy. I guess things have improved in the last 55 years!!
Thank you in advance for your time.
