This GSD21 was pulled during an electronics refit. It is in good working order. Perfect replacement for a downed GSD21.

DISPLAY NOT INCLUDED – Only used during testing to show functionality of the sounder module. This listing is just for the GSD21 and a power cable!

This module was tested with a sounder test set so the depth range will vary depending on what transducer you go with.

Thanks for looking!
