I just got my Elite 5 HDI today and hooked up the ice kit and all seems to work well, except I tested it out (in my house) and when the transducer is about 3 feet from the floor, the unit reads 9 or 10 FOW. Is this just because I'm in my house, or does something need adjusting?
Also, I was reading that people have downloaded updates for these. How do I do that?
