Speed Indicator?
Speed Indicator?
Recent owner of a used 26M and love the boat. In many ways I like this boat much more than my beloved old Pearson 323 but......do not have a speed indicator and am really missing that. Boat came with a Garmin 140 Fishfinder which gives depth and water temp. Transom-mounted transducer has a paddle wheel but the Fish Finder does not offer speed indicator. I've searched for a Garmin product which offers speed, depth, etc. and can't find anything which can use the paddle wheel. I would appreciate any ideas on how I can add speed indicator to my Mac without spending a fortune.
Thanks, Danny

Seems to me the GPS actual global speed information is generally more useful than a relative to current speed reading. Over-the-water speed accouning for current may allow you to gauge your performance easier, but you can just run up and back down the current and average to find the same info with a GPS. However, the over-the-water speed finder will not be able to give you overall usefullness of being able to figure your time made good, time to destination, location information, charting accuracy, and numerous other advantages of the GPS.

Further, paddlewheels are notoriously inaccurate. At best, they're accurate in only a narrow speed range, like between 7 and 16, or some such, with widening disparities above and below the range.
Paddlewheels come in hi & lo ranges. When anchored at night, fishing under my green lights and I prefer the low range paddlewheels because it tells me the current speed, plankton & baitfish can't buck a high current!
Yeah they do lie when going in a current either way. There are some new ones that are actually are self powered by the wheel itself, But I have yet to see any reviews. They are very sensitive as to where you install them and adjustment seems the norm, However they are a must for me!
