This is a DSM300 in good tested working order. We have tested this DSM300 on a E120 through seatalk HS network and also on a C120 through HSB 4pin network. The software has been updated to 4.20 so it is running optimally.

Made in Mexico. Comes with the power cable and a HSB 4 pin to 4pin cable!

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.

Shipping will be free in the U.S.
