I'm able to do this with my Helix to display (especially) the SI on two external 16" displays (one for left, one for right
). For your S&R you could hang a 60" 4K Display on it to see sunken cars and corpses in life size.
Sending the processed image as mpeg video stream to a phone wouldn't be any problem.
Unfortunately Humminbird decided to make the Apex, Solix, Helix not network compatible. So my solution will not work with your Solix.
But if someone would like to sponsor a Solix I will integrate it into my app.
It would be a very nice feature to train newbies if the screen could be mirrored over the internet. I thought about that a while ago.
If you have the possibility to connect two Solix via ethernet hub and be able to connect a PC we can build that thing.
