  • Fishfinders

    Fishfinders, also called Sonar, Echo Sounder and Fathometer, use a transducer to detect targets under your boat. Commercial fishermen use high powered broadband transducers with large color displays. Furuno marked the first fish in the 1940’s and their FCV1150 and FCV295 are unsurpassed in the industry.

    Fishfinders have evolved to included a wide array of features. For casual fishermen, low power and small displays are fine. For offshore fishermen or people who take fish finding seriously, consider a 1000 watt or larger unit. Performance is radically improved by using the correct transducer for your fishfinder . Call Technical Marine Support at 847-746-0100 or email john@technicalmarine.com for help selecting the best transducer and fishfinder to meet your needs.
