... consists of three components interconnected by 20 feet of cable: hand-held LED readout, float, sonar module. Simply pop in 4 AA batteries and your all set to detect the presence of fish and how deep they are from 2.5 feet up to 80 feet. Made for extreme ease of use with one-touch control this portable fish finder shows bottom contour and weed grass. This waterproof, marine-grade mini-might is small enough to fit in a tackle box so you can take it anywhere - it's about the size of a fishing reel. Couldn't wait to try this one out !
What I discoverd: The product works as described by the manufacturer and really is remarkable. My only hesitation, if any, is that it's somewhat awkward to use from shore because the underwater sonar tends to drift back toward shore due to tension from the cord and hand held display. To gain more practical information,I had an avid fisherman trial the device while fishing from a boat. Result, superb, locating fish clearly at depth is unhindered - the cord and sonar are not affected by drift and remain neutrally positioned in water. Durable, compact and reliable, F10C sonar fish finder is an impressive device that's sure to please any fisherman.
