Has anyone tryed a digital compass? What brand, how long used, and how reliable? With a GPS I don't see the need of putting a lot of $ into a compass. Any feedback appreciated. Would like a small unit for my montauk.

KVH is the only brand I know of with a flux gate compass ("digital").


A standard magnetic compass like a Ritchie works without electricity or Defense Department satellites. There might be something to be said for that.

One thing that attracted me to Whalers was the location of a nice large compass right behind the helm. Seeing a big compass mounted on a boat like a Montauk implies that the boat is designed for and capable of making passages long enough and far enough offshore that a compass is needed to navigate.

I have never used a digital compass. I do have a Ritchie S53 on my Montauk and am very happy with it. It doesn't take up very much room and sells for around $50. It's just there as a backup for my GPS.

I am rebuilding my entire boat and have been thinking about a compass lately. On a Montauk have you guys experienced much interference from the boats equipment mounted near the compass (Deviation)? I plan to mount a GPS and Fishfinder and am thinking I may not have enough space between instruments to NOT interfere with a mag compass. Anybody ever swing the compass yourself or do you need a compass shop to do it? Rex

I had trouble with the speaker magnet on my
VHF interfereing with the compass. With
a GPS, it's EASY to swing the boat. Just
set the GPS to indicate magnetic bearings
and run straight lines in different
directions and you can get a good first
order test. Unless you are doing serious
dead reckoning, you don't need to know that
your compass is off by a degree or two.
