I gave the idea some thought and agreed with my customer that there was a product missing for mounting a single plotter between the two legs of a 1" pedestal guard, without an "unsightly & large" NavPod box and that did not look "cobbled" together..
This is the design I came up with and it will fit most all 4", 5" and 7" chart plotters.
Since designing this mount I have been continually asked to do more and more of them. I finally decided to stop making the mounting plates on a one-off basis and now make them 10-20 at a time.
This allows me to sell them to boat owners who don't want to take the time to make one themselves. At $58.75 it is actually a very good value when you consider your time, the tools needed, and waste material. They are all pre-cut, shaped and ready to go..
