View Full Version : Altimeter on dash?

I'm often curious about the elevation of passes and summits on road trips and I was thinking it would be nice to have an altimeter on my dash. I know the better GPS units have this information, but I really don't have the need (read:cash) for one of those. Has anybody ever seen an altimeter that may work in the dash of a Jeep?
Thanks,
Billy

That looks the same as mine, but I have it on the other side of the instrument panel. I thought I got it from Camping World, but a search there and on Amazon didn't show it. Amazon did have a couple others, though.

Thanks guys. Is that for an airplane (meaning that the gauge far exceeds what would be relevant for a Jeep)?

Mine goes up to 16,000 feet, that's a little more than I've needed so far...

Here ya go Billy... it was $50. Mine is the discontinued Airguide model but this is identical.

It's not an aviation gauge.

John, i put an interior winch controller on the other side where you installed yours. This was the next best place i could come up with.

Who uses Altimeters when GPS units do the job so nicely anymore?

The nice thing about GPS is not having to adjust it all the time.

Since the basic altimeter is a barometer, if you don't reset it at a known elevation on your way to the mountain pass, it can be rather inaccurate.

We already have a cheap GPS that does (just about) everything we need (not into geocaching or anything at this point), so I don't want to spend more than I need to for more than I want http://www.slicky.net/smilies/shrug.gif

My GPS has a built in alt. but I don't use it. Since they turned off selective availability the elevation calculated by your GPS is as good or better than an Alt. Mainly because pressure changes do not affect them. Even your cheap GPS unit should do this. I have never seen one that didn't.

So is the altimeter on your GPS.

Depends on the GPS. For instance. With a Garmin 60CSX it has a barometer style Alt but you can turn it off and use triangulation from satellites for elevation. I do this on mine as it seems to be more accurate. I believe even the cheepo units will do this.

I'll check it out when I get a chance and report back. Thanks for the advice guys.

An altimeter only reads air pressure, so how do you adjust your altimeter each day? Just adjust it to read the proper height from a known position?

Back in my flying days, this was information that you had to get from the field that you were leaving, flying over, or flying to.

Of course the GPS takes care of that by measuring the actual distance.

This is the GPS that I got while I worked at Academy Sports and Outdoors. Might be a little behind on the POIs but I dont really use that function. Mine links up to 85%+ of the sattelites most the time. For the money it is great. Its also like running windows where you can do more vs a Mac like my roommates' Garmin is like (also a car unit). He has nothing but a map and I have all the extra goodies like alt, lat/long. etc.

Mine cost $40 new since we did sell the Garmins and these weren't the big seller and they got marked way down. (I'm glad I was behind the counter that day doing inventory and making new price labels.) Anyhow, best investment for my vehicle I've made in a long time. Not to flashy and not too pricey. If this cost $100 vs. the $50 the one function alt does, I would choose this personally. Plus some of the others on ebay are a little cheaper.

Which one is more accurate depends on a few things. If you have poor satellite geometry, the barometer may be more accurate. If you have large fluctuations in air pressure, the GPS may be more accurate. For the informal use that we are using our GPSr either method is more than adequate.
