DEEP STOPS. PYLE STOPS. Deep Stops. Sometimes called Pyle Stops Found by accident by Richard Pyle Don’t only have to be for Tech diving, recreational divers can also do them May help you feel less tired after dive Can be calculated at any depth during dive. What PADI Teaches You. 5m.

DEEP STOPS

PYLE STOPS

Deep Stops

• Sometimes called Pyle Stops

• Found by accident by Richard Pyle

• Don’t only have to be for Tech diving, recreational divers can also do them

• Can be calculated at any depth during dive

Dive with Pyle Stops

30m

Pyle found that when he stopped to collect fish at depth he felt less tired than

when he found no fish and went directly to the safety stop

How to calculate a stop

• Take the maximum depth

• Take the depth of your first deco stop (this will be your safety stop for recreational)

• Find the midway point between the two

• Stop at this depth for 1 or 2 mins

• Calculate the midway point between this depth and your compulsory deco stop

• Continue until you are less than 10m from your stop

Maximum depth = 30m

First stop = 5m

Difference = 30 – 5 = 25m Halve it = 12.5m

So you must go up 12.5m from 30m

30m – 12.5m = 17.5m

First stop = 18m

30m

Current depth = 18m

First stop = 5m

Difference = 18 – 5 = 13 m Halve it = 6.5m

So you must go up 6.5m from 18m

18m – 6.5m = 11.5 m

Second stop = 12 m

First stop = 18m

30m

Current depth = 12m

First stop = 5m

Difference = 12 – 5 = 7 m which is less than 10

Go to 5m safety stop as normal

Second stop = 12 m

First stop = 18m

30m

Some dive computers have the deep stop facility programmed in

Count down timer

It tells you the depth but you can program the time

Will also tell you the next deep stop depth
