Available Versions

These transducers have a permanently attached 10 meter cable ending in a brand-specific connector. If the owner changes their sounder/fishfinder equipment to a different brand, the transducer may not be compatible with the new equipment. Adapter cables are available for some combinations of new and old equipment, but not for all.

Legacy Adapter Cables

These 1-meter adapter cables are made for older transducer designs that have permanently-attached cables and which do not use the Mix and Match system. They enable a transducer with a cable ending in one connector to be used with a sounder or fishfinder that takes a different connector.
