I grew up working in a butcher shop. First job at age 4 was washing the kill floor, second job at age 5 was operating the chamber vac. I personally don’t see a need for a chamber vac in my life. I unfortunately just don’t kill enough stuff to justify it. On top of that, I don’t have a place to store it where I do my processing so I don’t want to have to move it or meat around to use it.
This year we did my buddy’s whole moose in an afternoon, 123 sockeye another afternoon, and about 250lbs of halibut/salmon/cod another day. VacMaster 380 pro was plenty for each job. 18 inch bar so we can do two packs at a time if needed and it’s air cooled. The only way a chamber sealer would’ve been more effective is if it was one that has room for 4 bags. I do whole bear hams, large packs (~12lbs) of deboned meat, and broth with mine too. It’s perfect for what little I’m doing. Maybe some day when the kids are older and we can get 500lbs of Fish a weekend and a couple moose a year we can justify a chamber!
