| Which GPS/Sonar Combo unit has the best shallow water performance. I fish a lot of shallow lakes (10 feet or less). Don't see a lot of arches on my current unit due to cone angle. |

| i've had muskies follow and swim under the transducer a few feet down, and i've also drifted over muskies with the boat in shallow water. they make REALLY big arcs on your sonar when they're that close. fun stuff.

Location: Grand Rapids MN | Playing with chart/screen speed helps some with getting distinct arches. I've used Lowrance/Eagle only before but going to pull the trigger on a Humminbird this year that has SI/DI. A feature they advertise called Switchfire which is the same as their previous TVG (Time Variable Gain) would seem handy for shallow water. Basically it allows you to still maintain your gain setting but it filters out surface clutter (low signal strength stuff) and it adjusts the arc sizes to a 'common' length. With DI you can adjust beam width and its more of a slice and not a cone so again it will help find fish on slopes and shallow situations. SI had been used for years for shallow water so I would seriously consider models with SI/DI. I really can't wait to try out all these new features and functions that I didn't have available on my LEI products. |
