I bought the lowrance elite4 at the end of last ice season and never had a chance to tune it in, so this year I thought I would have ample time to get it hooked up the right way. Unfortunately I ran out of time this season just when I was or thought I had it down. The thing I don't like about the lowrance is that they didn't provide a dvd to aide in the setup, I'm not one to sit down and read the manual and tinker with a product. I called their help line and they said everything I needed to know was already on youtube.....which is not totally true, for the amount you pay, they should at least drop a dvd in the box!
