Thanks Ike,
The inflatable came with a nice gauge...no numbers but green areas to indicate the proper pressure of the pontoons and the floor. The red indicator on the
pump only reads to about 3.5 psi so not something to refer for the higher pressure. I''m suspicious of the
pump as it stays virtually the same (with the needle about 1/4 way from the green area) whenever I check the pressure after another 30 strokes or so.
