  • Airguide Speedometer Conversion to GPS

    Ladies and Gentlemen,

    I am holding in my grimy little hands the first Airguide speedometer prototype conversion to GPS. I tested this prototype today and it appears to be working well.

    No more leaks or clogs!

    Stand by….

      How am I going to get rich if I give "a good price"

      Seriously, it is too soon to talk price. It will be competitive.

      From the front it will look no different. Some modification of the back of the case will be necessary and I need to explore the best internal mounting solution. Right now it fits into the current internal mechanism holder after removing all mechanical parts. A bit awkward my first try. I will work on this aspect. Hopefully, I can show photos of the internal circuit soon. All my questions are not yet answered but I am pretty excited about being able to offer this option soon.

          Yeah, but a smart phone doesn't look nearly as cool!

            Cool idea. Good luck. Will probably stick with my pitot driven Airguide though. I already have SG, and it is nice to be able to compare speed over water to speed over ground when we are on the river.

            To me, this forum is about love of inboard boats. It is about the sharing of information and, on a good day, some humor. It is not about post count, brand of boat, or any other superfluous labels that lend themselves to a false sense of superiority. Please, respect one another, try to pass on accurate information, and keep your eye on the ball.

                What kind of differences do you see and how is this relevant to skiing? This is a river issue and not applicable to lake use?

                  For free skiing, it affects how fast I am moving relative to the water. A boat traveling at 34 mph on the gps in a 2 mph current feels faster or slower to the skier depending on if the boat is traveling with or against the current. Having a traditional speedo (assuming I calibrated it in open water) to compare to the GPS gives me an idea of how much I would want to adjust the speed control to counteract the current.

                  This is a nonissue in a slalom course since speed over ground, which GPS measures, is all we care about. But in a slalom course, I'm relying on speed control and not paying much attention to my airguide.

                  Not bagging on your idea. I actually think it's really great. I'm just pointing out one of the advantages, for some, of having a traditional speedo in addition to a GPS speedo.

                    I didn't think you were "bagging". I just never really understood the importance of speed over water vs. speed over ground. I do understand the effect of current but not in relationship to skiing. As with all things it won't be for everybody... darn it!

                          Once you get this worked out, perhaps you can work with one of the phone manufacturers to make a smartphone that looks like an Airguide speedometer.

                              I need some input.
                              One of the limitations I am running into is the total sweep of the needle motor is 315 degrees. On a 3 to 50mph dial, like most of you have, the needle has to do one of two things.

                              1. To reach 50mph the needle comes to rest at 5 mph.
                              2. If the needle settles at the post or 3 mph it will not quite reach 50 mph.

                              How big of a deal is this? I know if I were calibrating for myself I would let the needle set at the post. I have never had a boat that would actually go 50 mph! Does yours?
                              The gps will actually read up to 200 mph. The limitation is the scale not being over 315 degrees. It appears that finding a motor that will cover a broader range of degrees is problematical
                              but I am not certain about this.

                              In YOUR opinion is this a problem that should be resolved before further developement?

                              Thank you for your input,
                              Dean
