New Airguide speedometers or GPS

I have a pair of new Airguide speedometers as well as new 'ballast tubes'...I'm debating on going with either the perfect pass GPS speedometer, the whole perfect pass system or try to keep it as original as possible. I've been using the tach for way too many years and it never seems to be correct in relation to mph

And another

Why not both options? One Airguide and one Precision Star GPS speedo. That's what I have in my 1994 SNOB. Redundancy -- belt & suspenders.

[If somebody wants my old and still working Aurguide, send me a PM]

JQ

Why not convert the original airguide(s) to gps? Best of both worlds- precise and original (appearance).

JQ does yours say Airguide or Nautiques above the pointer.

I'm thinking that's probably the route I'm going to go....I still need to check out the link.

I like the precision star I run both and I like the clock and the handy dandy compass.(you know when driving in the pouring rain and you can't see a thing) Oh not to mention trip meter is easy to figure the fuel burn later...

Under 5mph and over 45mph.

If your gauges sometimes work, then the issue you’re having isn’t with the gauges. Consider not scrapping/cannibalizing the internals when you convert. Send me a PM for details.

Yes, they can do the conversion to the older Air Guides, but I have not done it myself.

Over 45? I thought they read accurately up to 85 with the correct graphics?

(On a standard 50mph face).

Reasonably accurate (when properly adjusted), yes. Reliable? That will depend on your water conditions. Weedy or debris filled waterways will cause issues with pitot systems. They also cannot compensate for current if you care about speed over land (slalom course in a river, for instance).

There is certainly a place for a $200 gps conversion in an older boat. Originality (appearance), reliability and accuracy are among the benefits, as is simplicity (removing the pitot, tubing, etc) if you so desire. Not all disciplines require speed control, and a converted analog gauge compliments those that do... at a much lower price point.
