What the?? Air on or off???

Again-
Both of these situations could have easily been avoided by a proper pre dive check.  Lets not get complacent.....

Keep in mind Ed...I do think your idea is a good thing to investigate..I just dont want it to take the place of the proper pre dive.

If you can pull it off...and it can be a simple piece of equipment...go for it...i certainly think it has potential to sell..

G/L and keep us posted
