AirGuide Gauges - GPS Conversion?

[Zeke27G]

Has anyone here taken on the task of upgrading their original AirGuide speedos, with this Nautic Laugic "AirGlide GPS" retrofit?

For those that have either done the retrofit, or are skiing with GPS gauges, specifically in places with decent current, like the lower river, how do you like your GPS gauges?

Do you have to factor a plus/minus for the river current when pulling a skier up/down river?

Thank you!

Made me think, I just converted my Cobra to GPS, I never thought about boating / water skiing issues

From a "Perplexity AI" search:


To compensate for river current while using a GPS speedometer to pull a waterskier, you need to account for the difference between your speed over ground (as measured by the GPS) and your speed relative to the water (which affects the skier's experience). Here’s how you can do it:

1. Determine the Current Speed: Measure the speed of the river current. This can be done using a GPS device by noting the speed at which the boat drifts with the engine off.
2. Adjust for Upstream and Downstream:
   • Upstream: When pulling the skier upstream, the GPS speedometer will show a slower speed than the actual speed relative to the water. To compensate, you need to increase the boat speed by the current speed. For example, if the desired skiing speed is 30 mph and the current is 3 mph, the GPS should read 33 mph.
   • Downstream: When pulling the skier downstream, the GPS speedometer will show a faster speed than the actual speed relative to the water. To compensate, you need to decrease the boat speed by the current speed. For example, if the desired skiing speed is 30 mph and the current is 3 mph, the GPS should read 27 mph.

That "AirGlide" set up is a no-go, as they're out of their dual external GPS set up, which would allow me to use my existing dial plates. If I went with his internal GPS set up, I'd have to use his dial plates, that max out at 55mph.

Looking into other options, like Gaffrig and Livorsi, but I'm not trying to break the bank either, as this is a 32 year old boat.

Anyone have any luck with the cheap-o GPS speedos like Faria and/or Eling?

Any recommendations are much appreciated!

CPperformance had some Hardin GPS speedo's for 150 on close out. I got one for my Eagle, works great.

Bummer, not seeing anything in their "discount dock". There is a Livorsi, but it's 100mph max, which would be sorta goofy for my set up. Regardless,I appreciate the heads up!

Howdy,
I have an ’89 Barefoot Sanger, Suzuki 225. I upgraded both speedos to the Nautic Laugic AirGuide GPS using my original 80 MPH speedos years ago. Love it. We ski mostly on lakes so current isn’t an issue. Back in the day when we did ski the lower Colorado, the boat had the original AirGuide Dual water pickup set up so the speed was always accurate. I give them 5 stars. Quick turnaround, easy install. I may still have one or two of the original 80 mph Airguides sitting around somewhere.
Thanks,
Jim

Appreciate the info. I would have gone with the Nautic Laugic conversion, but unfortunately he was out of the Y splitters for the GPS kit with no ETA for the splitters, so I would have had to of purchased (2) GPS kits! Ended up going with Gaffrig GPS gauges. Tell me more about that Skylon pole, been looking at a used one, makes me wish I had planned for that before having our bimini re-done! Damn it!

As stated previously, I decided to go with Gaffrig GPS speedos. Sort of redudant having a pair of GPS speedos, but it just made sense, given my gauge cluster layout, and not wanting to mess with the original tach. The install was super easy, mounted the sensors on a small piece of aluminum bar stock off of the mirror mounting bolts just beneath the deck and the gauges worked great this past weekend. Really stoked that I didn't have to drill holes in the deck to mount the sensors!
