Hi again. I have a DDM 1 on my boat, and the LCD display is looking rather bad, though I haven't plugged it in to see if the thing actually works still. I have the Transducer with me, took it and the depth sounder out. I want to test to see if it works with my 2A 12V trickle charger just to see if it works. I think I'll send it in and get the display replaced, unless the cost is prohibitive. That is assuming everything works.
