Sun CompanyAltiLINQ - Dashboard Altimeter and Barometer | Altimeter for Car and Truck | Reads Altitude from 0 to 15,000 Feet

Wife really likes that I have it on our truck dash right in front of her for easy viewing. It seems to work very well at what it does. The key is to know the elevation of your house so that you can adjust it to that in the driveway and then should be good for at least a few hours depending on weather changes. No batteries to die make this a handy altimeter.

Altimeters are not accurate unless you can select the barometric pressure. This one has an easily adjustable barometric compensation, which then ensures the accuracy of the altimeter. This is exactly the same procedure used by pilots..."set the barometer, then read your altitude". Most budget altimeters don't have a way to adjust the pressure reading, so this one is an affordable exception. We live at 8,800 feet in the Rockies and after unboxing the unit, I set the barometric pressure and the altitude was exactly(!) 8,800 feet.The altimeter does have an extra calibration adjustment on the back that's hidden until you slide out the round instrument from the plastic holder. I never had to adjust it. The holder comes with a couple strips of stick-backed Velcro® and has a friction hinge that seems to be tight enough to hold up to most bumps in your vehicle.The one drawback others have noted is that the dial is a little hard to read, as the markings and numbers are kind of a light font. Otherwise, recommended.

Very portable. Can take in your vehicle or a backpack. Seems to work fine. A digital version would be easier to read.

Very nice gadget, and surprisingly accurate. As a retired pilot, I am always interested in elevation when traveling by road, through mountain passes, down to the coast, etc. Sure, GPS gives that too, but barometric elevation gives a different angle. Love it.

It was fun to use. As we traveled through and around Arizona, we found that it indeed was very accurate. From the altitude of around 8,000 ft. To the lower 3000 ft. Range. There were times when I might catch out of the corner of my eye, a sign stating the attitude. I would check with my new toy. It was right on.

These things are Awesome! I have them in 2 of my rigs now.

After reading the directions I set the device to my known altitude and took a drive to the mountains, the device measured the altitude accurately. I like that it doesn't a require a power source. I mounted it on my dash but I discovered in high temperatures (95+) the plastic mount, while staying stuck to the dash, did not grip the pivot pin tightly and the device tended to flop over. Hopefully in cooler weather it will tighten up again.

Extremely helpful if you have altitude challenges with the lungs. As we increase in altitude, at some point my husband's begin oxygen use. A brief Glace at the altimeter tells us to get ready for use. The opposite, of course, going to lower elevations, it helps to know that it is safe to discontinue.
