Depth Sounder

Ron T · May 13, 2014

I have two Antique Sandpiper III Datamarine Model 2450 sounder heads onboard. Do I have to replace my two exterior mounted sounder sending units also or is there a way to just replace the two heads ? Thank You.

I'm pretty sure you will have to change the ducer.

Actually Datamarine ducers are 120Khz and there is a replacement head. Sitex SDD110 or CruzPro D110 same unit different brand. Has an 0183 output. Good Luck

True, but they may not have the same connector.

In fact they will not have the same connector. I found that a minor obstacle and simply spliced the ducer wires to the connector that came with the head.

We've done it twice with no issues other than wire color codes changed.

Take look at Airmar, a transducer manufacturer, and/or give them a call. They have a good web site and a cross reference guide.
