Going fully hydraulic wouldn't be cheap, plus the pump alone is over $700. If you're okay without AP motoring out, are there still options to just add AP to kicker?
This. Picked up Vevor chamber sealer back in November. Used it to package 5 deer this year and operated flawlessly. Very easy to use, different sized bags for different cuts. I was trying to decide between this sealer and Vacmaster, but after some research, everything is made in China regardless of brand (was hoping Vacmaster was USA made). Although it weighs about 60 pounds, I'll still be taking this to the boat each weekend. Going to save a ton of time and money sealing salmon after they are fileted.

I've used these up to 400 copper. I'm sure they would work fine on a 500, especially if clipped to mono.

Can clean offshore, but need to keep skin on for identification. Also, you can't dispose of carcasses within 100 or 500' for shore.....I don't remember. We typically clean 'em in our last 30 min of fishing, so don't have to worry about distance.
