Arrrggghh
This is one reason I don't recommend the iPad a a primary nav source, and prefer hardwired gear.
I disagree here. Bad Elf makes a great GPS antenna that plugs into an iPad. Older iPads didn't have GPS modules so this was the only way to get them to work as accurate nav units.
An old iPad using Navionics and a Bad Elf is our back up navigation system. Works very well as a lower helm unit in the meantime using Raymarines app which emulates the main plotter in a fully functional display.
If the plotter fails I can use the stand-alone Navionics platform on the iPad. Bonus is the iPad can be moved to whatever helm you want. We've installed mounts at both helms for that purpose.
I just watched the entire presentation and it's absolutely fantastic! It answered so many questions that I've had over the years but never bothered to research.Here's a video from the 2017 Vancouver International Boat Show, a seminar on electronics. Its general enough so that he even though the date is "dated," the generalizations are still true:
Cool, I have an IPad. Will look at that as well. Thanks

I own a Raymarine GPS system for my center console. Now I am looking for a portable marine GPS for my new jetski. Anyone has experience with Garmin 78sc? From what I am reading about it, seems to have everything I need. Any other recommendations?
You will need back up power, probably a back up iPad and power at the nav station. A few years back I used the same system all the way to Prince Rupert.
