Yes, true. However, we don't have an integrated system. Even if we did, I'd still leave it out because around here the impeller would be completely fouled in about 3 days of non-use. Ours is centerline on the bottom of the hull -- it's either a dive down to clean it or swapping out the blank with the attendant geyser, every time we use the boat. Just too much hassle for a very marginal increase in data.

Remember, while bottom growth is about as fast as anywhere here on the Chesapeake, tidal currents are thankfully negligible in most places. Yes, there's a correlation.
