Recently I purchased from Doug at CameraLand the Kowa 883 with the TE11WZ eyepiece, TSN-EX16 1.6X extender, and the IPhone 5S / SE phone holder. Took advantage if the Kowa instant rebate, plus Doug threw in some extra holiday cash off since I called him the day after the holiday. This scope is fantastic! Shot my first F-Class at 1000 yards. The weather was coolish (70) deg and overcast that day, but I could easily see the bolt / screws holding the target number number boards at 1000 yds (high contrast white target board, black dark screws) at 25X. Also could easily see 1” dark silver pasters on the cream colored target paper at 25X at 1000 yards. Between relays I “looked around the place”, I couldn’t believe I could see the bolt heads securing the loud speaker megaphones at the target location, 1000 yards away. Their was no mirage that day, and very light wind.
Went to a different range and shot at 1000 yards a different weekend, but it was hot at 99 deg, mirage was bad, but could easily see impacts on steel at 800, mirage was so bad at 1000 couldn’t see impacts on steel, but could easily see the magneto speed hit indicator.
I should have purchased this setup 35 years ago when I started shooting. Get it you’ll love it. With the 1.6X extender you’ll have viewing ranges from 25X all the way up to 96X, plus the digiscoping with the iPhone is cats ass as well.
