Anybody own multiple Excalibur II's?

I bought another Excal II last spring, and it falses when it shouldn’t be.

My first Excal II in the area I was in tonight, I can run sensitivity wide open. It’s a sandbar about 1/4 mile offshore with very few targets. For the new Excal I had to back sensitivity down to 6 to get it stable.

I had an Excal II like that when I lived in Hawaii, luckily I bought from a dealer on the island who replaced it with other inventory. I knew it wasn’t right because I already had an Excal II that was fine.
