They've went up a bit in price MJ, cheapest I have found is $819 with a transom mount transducer. I was going to go with a GARMIN combo, but they're just to much money. So then I looked at a LOWRANCE, and have heard NUMEROUS horror stories with LOWRANCE and problems. I checked with SI-TEX and they're willing to cut me a killer deal, but it won't do everything I want. FURUNO is a top of the line machine so I think I'm going to go with a FURUNO 620 for a bottom machine and interphase it to a NORTHSTAR 550I external antenna and a fuel flow sensor added on for real time fuel milage. It's only gonna cost me about a $100 more than a combo and it will do everything I want without having to add in a NMEA2000 network. Plus if I upgrade to a larger boat with my 315HP MERCRUISER, the NORTHSTAR will interphase with the SMARTCRAFT ECM.
So how about some reports on that there 620 on the water.
