I have an older Kowa TSN1, good scopes are expensive for a reason. They last forever and have superior clarity and focus.
I use a Sightron 10-50x60, it's sits on my rifle.
Fwiw, I went to WSS and tried a few spotting scopes, yes outside. Too many models to remember, but at price point I didn't start seeing an improvement until I was at ~$800. The $200 scopes were lacking and the $500 scopes lacked a little less.
What I discovered; I couldn't afford a good spotting scope.
Kowa TSN-1 with 20x WA eye piece. If I every had to replace it I might be temped to look at a Vortex.
