Just replying to say what my dad used to tell me. There are no dumb questions unless you ask it twice.

Any of the garmin models with the panoptix port can run livescope, since you are talking larger screens... Any of the current UHD or gpsmap basically. Or you might be able to find a used Plus unit, all the bigger ones of those work too.

If you do ever decide to network, you can view everything across all your units.
