Has it been actually proven that they work? Are is it a must for the gadget guyz. I bet they gave they to all the pro's free to have them in their boat. I would have if it was my factory. When you race cars if you run the sticker are product you get paid if your a top winner. I'm sure it is the same. Do you think anyone who bought one would be slow to say they don't work just to save face. If they do work wouldn't you think everyone driving a 40 50 60 70 80 90 thousand and up boat would have two on board in case one failed on a fishing trip. I have asked people who swear by them to see the one they have out of curiosity only to be told "will I don't have one YET". WHAT??? I would hope they work but do they and where is the proof please.
TAKE A PHOTO HOME NOT THE FISH. CATCH AND RELEASE
Set the hook first and ask questions later.
