All and especially Alan and Willem:
Before you buy an Airmar dual transducer, read further...
I realize that you are looking to install something that will fix the failure of your Sonic Speed sensors, but it is NOT as easy as you may think.
My understanding of the B&G Hydra 2000 system is that the components and transducers communicate with the B&G Hydra 2000 via B&G language rather than NMEA 0183. The FFD connected to the Hydra 2000 computer does have NMEA IN and NMEA OUT, but NMEA sentences that connect to the FFD via NMEA IN, do not go upstream to the Hydra computer where it would be needed for computations requiring SOW such as True Wind. Additionally, your analog SOW gauge connects to the B&G Hydra Computer, not the FFD.
I have discussed this with Bill Kinney, and at least a dozen other people, some that know much more than me, and like I said earlier, I truly believe there are only two ways to overcome the Sonic Speed sensor failure and keep everything else as Amel installed it: Drill a new hole, or buy the black box SOG to B&G SOW converter. Refer to my earlier email for details.
The Airmar sensor that Bill Kinney suggested can be used, but other changes in instrumentation are required...Again, if you want to maintain everything as Amel installed it and correct a Sonic Speed sensor failure, I believe you have only the two choices I suggested earlier.
I hope this clears this up. But, if anyone has discovered a way to use the Airmar Speed/Depth transducer without changing anything else in a B&G Hydra 2000, please chime in!
