<p dir="ltr">One possible solution is an electronic (MEMS) heading reference system, which incorporates orthogonal accelerometers, magnetometers and rate gyros to produce a gyro-stabilized heading signal. Such an instrument would not need to be in your immediate field of view and could instead be mounted as far as reasonably practicable from ferrous structures and magnetic influences. You would need a display of some sort to convert the electric signal to a visual readout though.</p>

Note the compass heading at N when I am actually pointing west. The compass is in perfect condition, and works in the shop with all (Three ) electric systems turned on LOL. I am sure the gyro will go out of true in time but what choice do I have. I want to sink at the dock and travel submerged for 3Km instead of travelling at the surface for 3KM to get to my dive area. </div><div class="qtdSeparateBR" id="yui_3_16_0_ym19_1_1467038712343_7326">Hank<br /><br /></div> <div
