Scuba divers use this type of air bows underwater all the time, rather than the old rubber band stuff you stilll see on TV . Always wondered why some entrpeneur didn’t adapt this principle to above the water arrow flingers, though they could be dangerous without good safeties built in. They could easily shoot an arrow right through another swimmer like an above water arrow. Underwater you cock the cylinder to 2500-3000 psi by hand. Could post a picture and diagram had someone showed this old inexperienced in everything codger how to do post a picture or avatar or whatever without my kids and grandkids here to do it. Anyone that stupid whould be voted off here.
In any rate, I’m out of here. It’s been mostly fun, and somewhat educational.
