just got a lowrance high definition 5x last month with the 83/200 khz transducer.....holy cow batman! this thing is freaking awesome. its gonna cost a little more , but i got mine from amazon.com and got a really good deal. i replaced the unit i had on the dash / transducer on the rear, i will replace the trolling motor unit with the same graph as soon as possible. there are a lot of nice graphs out there though, just my opinion. i think you can watch the demo on the actual graph at gander mtn and maybe bass pro in person, its a nice outfit
