The Garmin Echo 100 wraps simple operations and Garmin’s exclusive fish
finder technology into an entry-level sonar. It’s perfect for any
vessel where space is at a premium. It has a waterproof 4" (measured
diagonally) screen and operates on a 200 kHz frequency to give a maximum
depth of about 180m. The wide viewing angle (60°) lets you see fish
even off to the sides of the boat. With an 8 level greyscale screen,
the Echo 100 has one of the sharpest screens for the money.
The
Fishfinder 90 also offers Ultrascroll™ which allows boaters to get a
much faster refresh rate on their sonar display. AutoGain, as well as
user adjustable gain, is also standard on all of Garmin’s new fish
finders. Audible alarms include fish, shallow water, deep water and low
battery. All Garmin Echo fishfinders have 2 years warranty.
