GPS Chartplotter Compass Interference?
I was about to purchase a Garmin chartplotter when I stumbled on an installation requirement of mounting the unit 20-38" from a compass depending on model.
The only practical location for a (small) chartplotter on my boat (and I suspect many others) is mounted on the binnacle behind the compass. That's within < 12". I'm wondering how many people have experienced problems with this mounting location as I know this requirement is not respected in many cases.
The alternative unit I was considering is the Standard Horizon CP180i. I was not able to find any restrictions on mounting location in the SH installation process. This either means SH does not have a problem with interference, or that the Garmin installation manual is more complete in its requirements.
Forget about Garmin vs. SH features... They both do everything I need and more. I'm only interested in whether or not Garmin's requirement about compass-safe distances is something I should take seriously when I compare the Garmin and SH products.
