CHIRP External Sounders
CHIRP sounders are external sonar units. The CHIRP transducer plugs into the sounder and the sounder box is connected to a multi-function display through a high-speed cable.
These sounders offer premium features such as support for dual-band transducers which are often not found in integrated fishfinder displays with their built-in sonar circuity.
Most sounders can only be used with a display of the same brand. The table at the bottom of this page contains a summary of all available CHIRP sounders.
