I have an opportunity to buy a couple of new ST-60 instruments, depth
and speed at a fair price
. Yes, I know they're discontinued but they match the wind
instrument I already have. I also have a couple of old Signet speed and depth
instruments that are marginally functional. The question is, are the thru-hull holes for the old depth transducer
and the speed wheel
the same size as the ST-60 transducers? I'd go measure them but the boats 250 miles away. Thanks for the help.
