Depth S200DL. I'm getting the MSD/18.8 of death. The boat has a gravity switch (2 transducers) and I get a blink of 11 before the 18.8 when I connect either independently or both. The display is very dim. Uncovered for some time.
We're looking to avoid a short haul to replace transducers. Do any of you know what to expect to see from these in terms of volt/resistance when functional?
I've already sent an email to DMI. I read that they're pretty good...
