BLUEMOMENT

I replaced it with an ST 60 only to find that it was the mast head transducer that was faulty. In swapping things about to find fault, I had to cut off the round transducer 5? way plug to make a connection elsewhere. The chain plugs are intact. It is still usable but will need a bit of deft connecting. Maybe whoever buys Doublet could use it as a backup. probs £25 life in it.
