Hi, my friend has just bought a boat with one of these fitted, looks to be original equipment from 1987. Does anyone have a manual or know whether you can program an offset as we would perfer to know the depth under the keel. Thanks Robin
I have the same sounder, the only adjustment is that toggle switch to change the depth alarm from 2m to 4m. They seem to be a bullet proof sounder so it would be shame to replace it. Maybe just write the draft next to the sounder so it can easily be subtracted by anyone looking at the readout.
Thanks Wander66, I thought this maybe the case, the unit is 0.7m above the keel so not the easiest of subtractions in a stressful situation, will just have to keep to deep waters
