How many psi do you put in your tube or toon
#17
About 3 to 3 1/2 psi for me with my tubes.

When I used to use a low pressure guage ...
(don't know what happened to it, I lent it to a "friend" and didn't see it again.)

2-3 psi was "bouncy" surface, would sag if put on the water, creases going or just gone, but reappear if you rest weight on it, making a depression.

3 psi was getting more supportive, all "creases" gone.

3-4 psi was "hard to the touch, no creases, but would make a slight depression from leaning on it" and that is the feel I still fill up to achieve now, and then stop filling.

4 psi was more hard to the touch, resisting pressure from a hand or elbow, and stitching was becoming visible in seams if you looked hard. The tube was feeling very strong at this pressure.
My tubes could take that 4psi pressure no problem, but one time I put a cut in my tube cover from a sharp edged broken reed while wading through a reedbed to a pond. I convinced myself that a little more give would reduce the chances of that happening again. (Try drawing a knife over something stretched very tight and it cuts easily more than another item with less tension.)
