Boracay, I hear what you're saying about "wheels that don't paddle." My wheel is coated with thick layers of bottom paint
. No telling how long it's been since it worked. The previous owner, an elderly gentleman, wasn't sure how long it had been out of service
Lancelot, the point you make about the single
transducer for speed, depth, and temperature is one that I have wondered about myself. While it is nice to have only one hole in the hull
instead of two, it seems that you would get more accurate readings from independent transducers.The single
transducers, however, don't appear to have wheels. Perhaps they are an improvement on the "wheels that don't paddle" problem?
In terms of the GPS . . . it seems that, as a cost-saving measure, the GPS alone (with the appropriate thru-hull transducer) would be the best choice. After all, it can provide the information that the combo instruments can provide, and, at the same time, show you your position on a chart.
Please correct me if I'm wrong here, but it seems that the primary benefit of the combo instruments is that they are easier to see/read in the cockpit
, and, if they are independent of the GPS, i.e., not part of a network, they will provide redundant information (which is beneficial if the GPS should fail).
Would be grateful for additional guidance in this fellas.
