[PSUBS-MAILIST] measuring an angle issue

[David Colombo via Personal_Submersibles]

Hank,
Do you have a thru hull for the transducer cable. We might need to make the
cable assembly up depending on your length needed to get from the OTS
Location to your transducer location. If your transducer is the same
frequency as the OTS unit, you might just need to make up an adapter plug.
Cliff has sent out the parts diagram when he built his and I ordered the
parts, so I know they are still available.  I will test my units next week
and then will mail you my OTS SB2010 unit so you can work things out. Send
me your address to SeaQuestor at gmail.com

Best Regards,
David Colombo
