I have always used PD units but on the new Rig I went with a Hughes Watchdog. Progressive makes a quality product but Hughes has some advantages.
It has bluetooth app which is handy to alert when it disconnects from shore and also allows me to see where power is being used between legs of power. This is helpful to see what use and voltage is on each leg.
I went hard wired as I don't need to worry about theft or extra moves hooking up as well as extra friction electrical connections. (plugs) that aren't always great electrical connections. I mounted it in with the rest of the equipment.
In the last year it has disconnected power twice due to under and over voltage conditions. Each time giving me an alert on my phone. Each time being an unsafe condition from the parks electrical.
