My Airmar triducer is broken and I'm waiting for the replacement. The issue is the boat
speed (BS) reads zero. The B&G
Trident has the option to use SOG as BS. Sounds good, right?
No. On the Trident and Zeus3 SOG will show up as BS. However, when calculating TWA from AWA the system uses BS which is zero. Hence, TWA = AWA. Could be other confusion from this oversight.
Seems obvious to me if the operator chooses SOG as BS, then make BS equal to SOG in calculations. Maybe I'm missing something and there is a way to make this happen.
