Question: Imagination question about scuba diving!?

( Back )

Answer #1:

A flash light that wouldn't scare away fish at night, aka light that only we can see.
A way to communicate between divers.
A better insulating suit.
Air recyclers: all that air that we breath out, it goes back into our tanks, but only oxygen, and nitrogen, this will allow us to stay underwater longer.
Underwater GPS.

Answer #2:

After several scuba drowning deaths in our area I thought of a can of compressed air with an uninflated heavy duty balloon/beach ball attached (in a day-glo color) all attached to a key chain pulley attached to the diver. When the diver got in trouble (tangled up, turned upside down, the onset of an air problem) he could press the button on the can, which would fill the balloon, which would shoot up to the surface so others could alert authorities/go down to help. I know nothing about scuba diving, but that is my safety idea.

Noted, this does not directly "help you explore" when scuba diving, but does give you more confidence re your safety.
