1/ What power output (Wrms) to the transducer do your i40 Bidata and Depth units produce?
2/ Also, my existing 6 blade paddle wheel might work even though it appears your i40 uses a 4 blade paddlewheel. According to your i40 instruction manual, your calibration allows for anywhere from .25 to 2.5 multiples of speed, so I would think 0.67 would work when using a 6 blade paddlewheel vs a 4 blade one (of course I may not have thought this through 100%...LOL). Does this sound correct?
