I've never seen these. If there not on the market already, would you buy a otterbox or similar rubberized cover to protect your 600 dollar plus graph from drops? Even if it was $150. I thought of this today, seems like a great idea to me what do you think?

no

No

A good alternative cheaper is what a lot of guys use,
a 4 pistol size case or similar plastic gun case.

I use a couple of Plano aluminum pistol cases for my large screen SI units.

I have patent pending product being developed to cover hds 10-7 and humminbird 1100-800. Will cover these unit while on the mount or off when not in use. Will post when ready.

Sounds interesting. Ready to see some pics.

The first sample being made is for a HDS 10.You will be able to use while trailering or removed for storage. With or without a ram mount. Will post when I receive it.
