There is a Magnetometer on your phone (who knew!)

I found a cool free app that should help locate the sensor. It is Gemeco iNstall. It turns your phone into a Magnetometer which measures local deviation. After you fire up the app, you can move it around and see how much deviation there is at any location. It is amazing to see it go from 2º to 90º in one foot as I move by the fridge in our house. The magnetic door seals really light it up.
Raymarine says they can handle 15º but recommending 10º max.
It also has a tilt meter to show deadrise and a wire sizing calculator among others.

I have a couple of preferred locations to install the sensor core for my new EV-100 pilot but according to the book, might not be the best. I am looking forward to seeing what this thing tells me.
I am thinking it would be handy for anyone who is having problems with their AP holding course to check their location.

Different AP, however when I installed my new AP I found the app. Very helpful and kind of fun to wander around checking the magnetic fields. Just be sure to wear a tin hat. ;)

I got my EV-1 installed behind the drawers in my C30. I checked the location with the app and it showed only 5º deviation but some other locations in the cabin showed 20º or more. If I got within 12" of my speakers, it pegged the meter at 90º.

Now, see there, that’s what I really like about this forum: that right there is some real actionable information! Where else are we going to get that kind of timely advice? Nowhere, only right here!

PS: was that a custom made model, or one of those one-size-fits-all deals?
