Did you look at using a used turbo and blow compressor air in one side
and use the boost side as a vac? probably could get some better results
that way I would think.

I'm having better luck with the prototype than a shop vac already,
just trying to improve the lift. Toting a generator isnt really an
option.
I also just have a shop vac hose, if theres moisture the dirt collects
on the sides with a shop vac and loses lift. That's how I've always
dug post holes.

powered vacuum producers work but I don’t know how well. Sometimes
they are called eductors or ejectors.
Take a look at this one:

I need advice from you nerds.
I'm a broke joke, so hydrovac isnt in my budget. Besides, I want
dry spoils to put back in the hole.
This revision works for venturi. I have multiple size reducer but
right now I'm just doing 3/4 to to inch. The 3/4 to 1 then 1 to
half back to 1.5 for the venturi side seemed to have the best
lift, but the hardware store didnt have everything, so it's all in
2 inch right now
I'll dump to a 2000lb peanut sack if I can find one, but for now
I'll just use a 30 gallon drum and dump on the mega movers.
This is for use in conjunction with the airspade I did have some
coin to get.
Venturi math gets complicated and I'm full retard so I need to
find he best ways to increase negative pressure and where to drill
the ports.
I also wonder if theres an option to recapture the exhaust into
the airspade.
I need you nerds to go full geek.
If I can get valves correct I'll have the local machinist make me
a couple that are pressure rated.
This is to mimic the airvac I also cant afford.
This proof of concept has the lift to clear potholes and
handholes, but I need to clean it up and get more efficiency.
A side discovery is that this setup is perfect for blowing straw
and seed with glue
