Can anyone please tell me how many pulses per nautical mile are delivered
by the B & G Sonic Speed system.
The B&G "Network" paddlewheel puts out a nominal 6.25Hz per Knot (at least
6.25 Hz is the factory-standard calibration setting). That would work out
to 6.25 x 3600 = 22,500 pulses per nautical mile. This is very likely the
same paddlewheel sensor that the Sonic unit is emulating.
