The FF520 Fish Finder option brings high-end fish finding capability to Standard Horizon's CP155C, CP175C and CP1000C WAAS GPS Chart plotters making them the ideal choice for casual or professional anglers alike.

The FF520 Dual Frequency (50 and 200kHz) Black Box Fish Finder's advanced filtering eliminates unwanted noise and sharpens return echos for enhanced seperation and detection.

Transducer ID™ allows the FF520 to query the transducer (sold separately) to determine its perfromance characteristics. Power output, frequency, beam pattern and other unique transducer characteristics are sent to the fish finder. this data allows the fish finder to fine tune itself to match the transducer which optimizes overall system performance. No matter what the conditions, you will be able to fine tune your fishing rather than the fish finder.
