I have found 2 small electronic items that had a powerful influence on the compass - a hand held radio and a cell phone. The effect was particularly bad when clipped on to a binoculars holder mounted in front of the binnacle. That binoculars holder has held all kinds of things that affected the compass and I am more careful with what I put in there now. Screwdrivers, rigging knives, spare or spent AA cells, pliers, - all had measurable effect and are now banned. Aluminum beer cans don't seem to be a problem and they fit nicely.
I agree with all the comments about not worrying too much about your chart plotter, so long as you take a thoughtful approach to the power leads and test your set up. -----Original Message----- From: CnC-List [mailto:cnc-list-boun...@cnc-list.com]On Behalf Of Chris Ford Sent: Friday, January 25, 2013 8:39 AM To: cnc-list@cnc-list.com Subject: Re: Stus-List Mounting chartplotter near magnetic compass (ChrisFord) Thanks all for your ideas on this one; your input will help me find a work-around. I guess the manufacturers' guidance is there for a reason, even if the reason is CYA! - Chris
