[PSUBS-MAILIST] Personal_Submersibles Digest, Vol 136, Issue 18

[Jon Wallace via Personal_Submersibles]

 I, and most others I believe, are using the existing transducer cable which is regular shielded RG58.  I wouldn't recommend anything else since there are likely impedance matching reasons OTS selected RG58 to the transducer.
OTS ties the shielding to the supply power ground (vss) via their circuit board.  I've traced this with an ohm meter.
I have nothing grounded to the hull and I don't think it is a good choice for our vessels.

All,
Which type of cable are you using to connect the transducer to the OTS unit? Is it shielded, and if so, what do you have the shield tied to? Is it grounded to hull, and is your DC negative grounded to hull?
