Hi guys, I own a Fisher F11 and have had it for about 2 1/2 years now. It's really an awesome detector and has surprised me with it's performance for such a basic detector. I originally bought it for my wife to use but you know how that usually goes. I ended up using it myself as it's a fun detector. Problem is the detector started giving my problems first not turning off. Then it wouldn't turn on either without removing and then replacing the battery. Now it won't do anything at all! I'm really bummed because I have to send it in to Fisher. My questions are: 1) Has anyone else experienced this problem? 2) How is Fisher's service and turn around time generally speaking? Thanks for your responses. HH George
