Guys, I feel everyone that has a TM mounted transducer should look into one of these. If you frequent shallow water, or trolling around alot of shallow brush quite often, these things are great. Even as simple as trolling up to a tree where your bait is hung up, This thing could make the difference between buying a new transducer(which we all know aren't cheap) and not. You could spend $40 bucks(or less if you get in on one of his deals) on one of these and never have to buy another transducer again, or everytime you break one, have to spend a good 50-60 bucks on a new transducer. I was abit skeptical on getting one myself, but now that I have one....I definetly wouldn't hesitate to buy another. :beer:
