Garmin FF 100 Description The Fish Finder 100 is a full-featured 200 kHz sounder with temperature that's both waterproof and affordable. It rounds out GARMIN's complete line of sounders which includes the Fish Finder 160 and the Fish Finder 240. Although similar in features to both of these products, the Fish Finder 100 boasts one distinct difference: a lower price tag which makes it the perfect entry-level GARMIN sounder unit.
On the outside, the unit comes packaged in an attractive case that measures 5 w x 4.9'' h x 2.5'' d. The 2.5-inch diagonal display that makes detecting fish easy on the eyes, and it delivers the big picture thanks to a blue/green LCD STN display with 160 x 100 pixels. Even better you don't have to worry about this unit getting splashed as you reel in your fish because it was designed to withstand immersion in one meter of water for up to 30 minutes.
But it's what's inside that really makes the Fish Finder 100 so impressive. The unit comes standard with GARMIN's exclusive See-Thru technology that allows it to hear both weak and strong signals at the same time. A graphic whiteline also included on the Fish Finder helps present a clear image of bottom hardness and structure. The benefit to fishing enthusiasts is a sounder that will detect fish even when suspended inside structure and thermoclines.
