Manufacturer:

Model Number: RT-300

Series: ADF

Listed Item Condition: Used

Product Details:

This unit was pulled from a vessel being refit with new electronics. We were not given any other parts besides the DCU. We were able to find the pinout of the power connector online and were able to apply power to the unit to show that it is powering on, buttons are functioning, etc.

Cosmetics on the unit are good, not perfect, there is an area or two where the black powder coating on the aluminum housing is bubbling or has flaked away, but otherwise, the unit shows well, screen is completely clear of any sun damage, etc.

This would be a perfect replacement head for someone with an RT-300 system that has experienced a DCU failure, or someone that may want a backup DCU.
