This is a DSM300 in excellent tested working order. We tested both HSB and Seatalk HS ports to confirm functionality. The software has been updated to 4.20 so it is running optimally.

MANUFACTURED in Mexico!

This was removed from a boat that was being refit with new electronics. Transducer not included, display used for testing is not included.
Unit has been bench tested here and found to be working, we ran it for about 2 hours on a 12v power supply on an E-Series classic without any issues.
