A little dissappointed with the new speed sensor on my new Eagle ST. WOT it read 80 MPH!!! Gee, maybe I set a new TF record! LOL It only appeared to be accurate up to about 20 mph. Which is good as my in dash speedo doesn't even start until 20. Is this normal? Is meant more for trolling speeds? I seem to recall the manual say it was accurate at speeds up to 70+ mph. Yeah, it goes that high, but my boat doesn't! Any clues? Other than than, I love the units. Will take a little while to get familiar with all the features. Boat runs like a champ too. But I am defiantely taking on water, and I don't know where. And not a little either. Probably have to drop it off at the shop with a grand! LOL
