Garmin has a rebate on right now for a Panoptix and Echomap combo. I already bought an Echomap for the bow so I'm considering the PS21. I crappie fish all year chase sandies and hybrids all summer especially top water in mornings and evenings and do some catfishing also. If you have one how do you use it and how well do they work. Some of the videos I've seen are impressive.
