I loved my 15’s, but everything else you’ve written matches my experience with Swarovski 15x56 and BTX 65mm. The extra weight and bulk of the BTX is a bit of a pain, but I still pack it everywhere. Even when glassing relatively up close (less than 1000 yards) I thoroughly enjoy using my BTX. When I arrive to a glassing point I triage the landscape through a set of 8x binoculars, then get to work picking the area apart with the BTX.I didn’t like 15’s that much. I packed 10’s, 15’s, and a 20-60x80 spotter. I used the 15’s the least.
I got the BTX/ATX 95 and quit packing 15’s.
I don’t know if I ever spotted anything with 15’s I didn’t with the 10’s. With the BTX I spot stuff all the time that is out there that I didn’t pick up with binos.
They are so different it’s hard to really compare them.
I have ALOT of experience with the 85mm BTX and a little experience with 15's. In my opinion they are two different animals. For me the 15's did not give me enough over my 10x42 NL's for me to have any desire to have them. I tell people all the time that the BTX is as close to cheating without cheating. Their is nothing better for FINDING animals. It is not the best for judging sheep rings or telling if a bull elk is a 350 or 360 bull from 4 miles away, but you will see them! I hunt extremely remote backcountry and I always carry it. People say I am crazy for bringing it with me into the place I go, but I usually kill stuff and they don't. So for me it's a no brainer.Any one have any experience with 15s and BTX. I am courteous to hear opinions on when one would out shine the other and visa versa. i Am looking for responses from those that have used them.
Thanks
