Digital compass for bike
Hi everybody.
I am looking for a digital compass that can be mounted on a motorbike. The compass must have the ability to give the true heading rather than magnetic, and it should be able to correct for the influence of 200 kgs of steel sitting underneath it.
Digital compasses on steel boats can correct for the resultant compass error by circling slowly through 720 degrees, which allows the compass to figure out the error due to the steel of the boat.
Such compasses usually are largish affairs consonant with the fact that it is sitting on a boat. I am looking for something small enough to sit easily on a bike.
Anyone have any experience of such a device?
Thanks
Geoffrey
