I have two Onix 10 graphs, one is a SI the other is a cross touch. I have them networked together so you get SI on both units.
They will also share one map and way points.
They are both touch screens, have the joystick and on the fly wheel adjustments.
They are TOO much technology for this old Texan.
I want to trade for a Helix 10 Mega Si and another Helix 10, as long as I can network them to share way points.
PM me for more info.
I am located in central Texas would like to meet face to face.
But would consider shipping, maybe.
