After 10 years it's time to think about an upgrade to the chart plotter. Who navigates by pilotage or dead reckoning anyway? ;-)
Looking at a Garmin 4208 or 4210 but two questions:
1. Looking at the pedestal which has double bend, it looks really tight to fit a navpod that's big enough to hold the unit above the compass and below the bend where the pedestal goes vertical to hold the depth and speed instruments.
2. In the Garmin manual it recommends not mounting the unit any closer than about 30" from the mag compass to avoid interference. Is it possible to compensate the deviation out of the compass?
Has anyone installed either of these plotters.
Many Thanks

Even though I have a Garmin 2110 chart plotter. I still have and use my charts when we go on trips, It is something that a prudent sailor should never get away from. If day sailing it is a different story, usually in familiar waters so we do not use charts.

I was kidding about not using charts.
I am interested though in how the installation is done with these larger chartplotters and what effect they might have on the compass. Currently have a small Garmin 162 but it is getting to the end of its service life.

One might consider that the number of people using chartplotters at that location has risen dramatically in the past five years, and I've yet to hear of anyone getting lost because their compasses were disturbed.
Someone reported a 3 degree deviation on his compass from his new chartplotter, when it was on. When the unit is turned off, the compass was fine.
When you install it, just check the compass with on/off on the chartplotter.
You can also develop a deviation table for your compass if you haven't done so already.

I went over two years before I discovered my binoculars in the pedestal guard holder were impacting my binacle compass by up to 20 degrees.

So I will not worry about the compass.
Any problems with installing the navpods? The bigger ones run about 12-13" in height and it looks like anything much bigger than 11" may not fit on the doble bend pedestal.
Thoughts? Has anyone actually installed one of these bigger pods?

I changed out my pedstal guard to a 1 /14" by 58" high with one bend. I then installed the Raymarine radar with chartplotter into a NavPod. This system is mono chorme, so on the starboard side of the guard I have and Edson arm which holds a color Garmin 540 chartplotter. My compass did not vary even one degree. The compass is a 5" ritchie Stainlees Steel. Also my Auto pilot is mounted beneath the compass
Good Luck

I have the 4208 on my boat and it is only about 6" away from the compass and it onl effects it by a couple degrees. When the chartplotter is off it doesn't effect the compass at all. I have to say that I love the 4208 so it is well worth the 2 degrees variation.
I put in a new navpod for a Raymarine C80. The pod is 10" high and, being just under 6' 3" I find it slightly blocks reading the compass. I have to bend down a bit to read it though the Admiral, who is only 5' 4" does not have a problem.
I'd think anything bigger than 10" will be too large.
