DT,What do you think about the Furuno FCV-620?
Go Garmin if you want it to last forever it is very simple to use. I have a 546's with the blue chart chip in it and love the pictures. I also got the transducer that mounts inside the hull, it reads no matter what the speed and never hangs grass.I had lowrance for 8yrs before making the switch and they are very easy to use too but just did not last for me. The new Lowrance DTS I think it is called seem to last better as they finally made them waterproof.Capt Matt
So, if you are anywhere within 10 miles of Anna Maria next spring, be afraid, be very afraid.
