so anti-algae wax seems to survive a season.
I like forward looking fish
finding stuff. We are, have been wreck divers for some time. Our first GPS
way points were all shipwrecks. When I saw a map of one of the wrecks I visit in colour 3D I was in love love love. Folks use their iPads but they don’t like the sun. Ours is at the nav station beside another plotter running entertainment via a wisa broadcast system.
We do have some oddball homemade electronics
my grandson and I made. Raspberry 2 cameras a servo shield 8 relays 2 stepper motors and I 3D printed a water
proof container for it. We made a dissolved oxygen sensor
on a breadboard. It was really interesting.
Kudos to you if you can make all that stuff work
and show up on the screen
We have name brand no issues at all. We have not added radar
but it’s a consideration.
