Hi,
Question about old depth sounder and transponder. If you take a look at this youtube Video I took by shoving a gopro up my ol' sole hole you can see my depth transponder that was installed by the original owner (OO) I am guessing.
The depth finder and knotlog each their own transponder and after watching a couple videos of sailors having their thru-hulls punched by choppy seas I thought I should get an understanding of what I have. The knotlog has a paddle wheel transponder albeit broken, under the dinette seat and easily accessible. The depth transponder is in a place where I cannot access and wonder how it was installed. I see no evidence that it is a thru-hull from the exterior, maybe the contraption surrounding the transponder is a in-hull adapter?
The stuff is all Signet and from what I can find it all dates to when the boat was new in 1986.
My question is if anyone would know if these transponders are likely to fail, I think I can reuse it if I find another depth sounder that uses a 200khz transponder. I am not sure yet that I dont have a bad wire because the depth finder reads 18.8 which is coincidentally what the newer models read when I see them on ebay (default no signal read out?)
The transponder wire is labeled mk272.88 - 200khz with a RCA plug. Will a continuity check show anything?
I would like to have a depth finder but do not want a transom mount or drill a thru-hull, especially if I might have something already there. I think it was stingy sailor who has a thing on converting RCA to two-wire for newer units.
