Garmin echo 151dv

The Garmin Echo 151dv is a powerful fish-finder that is simple to use, coming with a surprisingly powerful duo beam sonar that delivers a clear photographic view of fish and structures beneath your boat. It has a small size and features a compact design that makes it quite portable.

The Echo 151DV comes with a 77/200 KHz HD-ID/DownVu transducer that includes transom and motor mounts. It delivers narrow-to-wide viewing angles that give you a bigger picture far beyond the sides of your fishing boat. It’s compatible to 50/200 transducers that may be purchased separately.

Key features of the Garmin Echo 151dv

Display features

This Echo DV comes with an 8 level grayscale display screen that shows results from the sonar. Generally, the screen is relatively small, with a diagonal measurement of 4 inches, but on the other side it makes the device portable. The screen can easily be read even in bright conditions. With the small price that it goes for, the screen resolution of 160 x 256 is just okay.
