Nov 25th COVID-19 UPDATE: We are open for business!

Walk-ins are not allowed but orders may be placed online and picked up at our warehouse.

We are shipping orders as fast as we can with a limited staff. 
Some shipments will be delayed 
regardless of status shown on the website.  
Mercury factory backorders are common (getting better) right now and we have no guarantee of release dates. 

 UPS has suspended service guarantees and delays are common (getting better!) and beyond our control. 
We are sorry to say there are no refunds for late shipments at this time.

LUCKILY we have been stocking parts for over 40 years and have an enormous selection of parts that ship the same day! 

Please email us with any questions!

Thank you for your patience and stay healthy!



For serious deep-sea sportfishing the GSD 26 takes high-definition targeting to a whole new level. With a compatible transducer the GSD 26's Spread Spectrum technology scans on multiple frequencies at one time returning vast amounts of data to the receiver. As a result you can expect precise shallow-water-like target separation at much greater depths - up to 10000 ft (3000 m). A traditional fixed frequency mode allows you to manually adjust frequencies from 25 kHz to 210 kHz for enhanced targeting of specific fish species. You can also adjust transmit power from 300 W to 3 kW (depending on transducer) for even more control over your sonar returns. Dual-transceivers allow simultaneous and independent transducer operation.
