Car compass like boat or airplane compass vary depending on what electronics are working. Electronic compass require power. Traditional magnet type compass come in two types: free moving and dampened. Most boat and airplane compass are dampened and have corrections. I like my trusty old Boy Scout Sylvan compass for back packing. Be careful while hiking, Your belt buckle, camera, binoculars hanging on your neck can through it off. Check aviation charts for the current magnetic correction. It can get pretty wild in Alaska and Canada.

If you plan to buy a good quality compass, avoid Tates. It's been known for over one hundred years that Tates compasses are unreliable. "He who has a Tates is lost."

I've used a couple of in-car GPS systems, and none worked as well as a Garmin.
I prefer maps

Don't have a GPS in my car. Never liked Mapquest on line, would always take me the long way. Google Maps is good, use tablet at Starbucks before go places have never been. However, it helps to know how to read a paper map (AAA).

As some Hoggers whom took Jerrys post seriously and turned the post to real compasses and the use of I figured for your information this up to date story on the ever moving magnetic north " pole" -

The location now is now a long way from where is was when I retired from the survey field 25 years ago. At that time the adjustment for declination where I live was about 2 to 3 degrees West. It now is 7 and 1/2 degrees West. Makes running compass lines much more difficult. Thank God for the the new very accurate GPS units that makes the running of these lines practically obsolete.

D. W. Brunton's "pocket transit" surveyor's compass. No longer advertised, no "buzz".
150 years and counting. Superb instrument.
Cammenga: exclussive supplier to the US Army since 1992. Inductance damped.
Officier's model 3H has tritium illuminator. CEO Michael Cammenga--I've spoken to him:
very honest guy.
I own both: great compasses. Excellent.
