Which model HELIX 5 did you get don3778?

Pros for any model would be that you will be getting 2D sonar information from the location that you are fishing and not some 10 to 20 feet to towards the back end of the boat. Cons would be that you would not have the HELIX 5 unit at the console where you may need it while making a run in your boat or when quickly scouting out new fishing locations.
