How do you communicate pressure?

[The Kraken]

In 100 PSI increments. 2 digits.

The numbers 1 through 5 are given with the fingers vertical.
The numbers 6 through 9 are indicated by holding the fingers horizontally.

Case in point: 2900 PSI = 2 fingers vertical followed by 4 fingers horizontal

900 PSI = signal 0 followed by 4 fingers horizontal

1000 PSI = 1 finger up followed by 0

1700 PSI = 1 finger up followed by 2 fingers horizontal

I guess you've figured out by now that the horizontal fingers indicate 5 + the number of fingers extended.

Using one hand we use a finger per 100 PSI and flash as many times as needed.

1000 would be 2 flashes of 5 fingers

1200 would be 2 flashes of 5 fingers followed by 2 fingers.
Many will post with a plethora of other schemes bordering on Chisenbop. What I like about the system we use is that anyone can pick it up in a pre-dive briefing

These all work best when you echo it back to you buddy and he gives you the OK sign that you got it right.

Same here.

Show my buddy my pressure gauge. Seems pretty simple to me.

This is what we do to, quick and simple, no guessing

Ditto on letting my buddy read my remaining air for herself.

A thumb up ! any other questions I just swim over and compare spg's.Turn or surface pressure is written on our wrist slates.No other communication is needed.

fist for 50 or 75 bar

"hey why are we stopping"





In california each finger is 100 psi.... and you talk on one hand.

Where I dive now... we call 100 (T for ton).. then 50 (fist) bar.

I just read the GUE/DIR book... fark me... thought KISS was a core concept.

I also don't see what the prob would be with both hands showing a 5 and a 2, meaning 7 or 17 if a single digit was thrown first.

I don't want to use both hands to communicate pressure, that's all. YMMV.

The question might be; if I flashed a single digit (1) and a two handed 7 would you not want to understand 1700?

each 100 lbs is a finger pointing up--to 500 lbs(example 300 psi would be 3 fingers, 500-5 fingers up), 600 thru 900 lbs is a finger pointing sideways ie counting 6 thru 9 using your fingers(example 700 lbs would be index and middle finger pointing sideways)...........1000 is index finger laying on forearm and 2000 lbs is index and middle finger laying over forearm(example 1500 lbs is index finger on forearm followed by 5 fingers pointing---2700 lbs is 2 fingers over forearm with index and middle finger pointing sideways).........

The above sounds a complete nightmare when wearing 3 finger mitts or when narked.
