Fishfinding with Garmin DownVü Scanning Sonar
The echo 551dv is a premier fishfinder with an all-in-one transducer that delivers both advanced HD-ID 77/200 kHz and Garmin DownVü scanned images simultaneously on a horizontally or vertically split screen. The images provide the clearest possible fish arch returns and nearly photographic bottom/structure details under the boat. With its bright, crisp 5-inch high-resolution VGA color display, the echo 551dv has Smooth Scaling which provides smooth transitions from shallow to deep water and back again. Narrow-to-wide viewing cone angles give you a big picture well beyond the sides of your boat - from shallow water down to 2,300 feet maximum. Also includes sonar history rewind and 500W (RMS) power. Quick-release tilt/swivel mount plus transom and low-profile trolling motor transducer mounts make installation a snap.

Comments about Garmin Echo 551dv Fishfinder:
I have always been a Garmin fan and user. I currently have 6 different Garmin devices and love them all but this one. The 551 DV. It's really not the device itself but the transducer. Unfortunately this transom mount transducer is the one you are going to get with all there downvu and sidevu units if you want to go with a transom mount. I understand there's different technologies in them but the shape design and mounting bracket are the same. I mounted the transducer as per the instructions, got good readings but I had a huge rooster tail that just engulfed my motor. I talked to some electronic guys and they said it was too low. So I started raising it and the rooster tail got better but never went away but as I raised it my readings got worse. I started doing some research and found that people that where having the same problem put splash guards on them witch doesn't seem acceptable to me. I called Garmin several times about this issue and they recommended different mounting brackets, one for the bottom of a latter and one on the engine mount witch would mean I couldn't use while moving. That was not a possibility. The third option was a through hull mount. Ok, then I found out they start at $450. Even though I feel comfortable mounting transom mounts the through hull I would want someone who knows what they're doing and that would be at least another $300. I haven't had my unit for 60 days yet and now find myself shopping different brands. I am currently looking at the new Lowrance Elite 5x chirp witch is $550. I would save money getting it and have more technology because it has chirp witch the 551 DV does not. I plan on throwing the 551 DV in the trash because I wouldn't even give it away. All I am saying is stay away from there downvu and sidevu transom mount transducers!
