Calibrate Compass

[Ron H]

2017 Allegro Breeze, How do I calibrate the compass?

 

[Kevin D Pem]

Depends on the compass.

 

[Ron H]

It's a magnetometer somewhere. (?)

 

[Kevin D Pem]

So electronic. Look up the manufacturers instructions. You will likely need a large empty parking lot.

I needed empty Ocean to set My boat auto pilot. But your initiation sequence would likely be different based on manufacturer.

You move the two iron balls left or right to find true magnetic N.

Yah, that's what they do with an old school compass, not the same as the electronic system he asked about.

My suggestion is to call the manufacturer of teh compass, or at least get a manual.

The one in my Expedition said in the manual to put it in the calibrate mode. and drive in small circles 3 times then turn off the calibrate mode.

That is what I was thinking, the question is how to put it in calibration mode.

I can't see that Accuracy is All that important on land but it might be.

In boating, the compass is the most mis-understood thing aboard; the anchor is second.
The cal mode was in the owners manual that came with the car.

I assume you mean non cruisers.

/I assume you mean non cruisers.

Even cruisers. I belonged toa cruise club where the leader went tree-to-tree and the rest followed.
Since I taught navigation/compass/piloting I was good at it. 30 miles out at sea, fishing, with only a compass, chart, depth sounder and VHF radio. This was a normal trip.
Just because someone owns a boat it doe not necessarily mean they know something about it....

So true.
