Mention a “deep dive” and watch the reactions. Novice divers want to know what it’s like.

More experienced divers who have been a bit deeper chat with excitement.

 

Those qualified to venture to 40 metres/130 feet – the recommended farthest edge of recreational diving – also show enthusiasm,

though somewhat tempered with respect for the challenge deep diving presents.

 

There’s something a bit attractive, exciting and mysterious about “going deep.”

As a new Open Water Diver, 18 metres/ 60 feet marks the depth limit to which you’re qualified to dive.

This limit isn’t arbitrary – it’s based on no decompression limits, nitrogen narcosis and air supply – but even if you’ve only made a few dives,

you may be curious about deeper dives, perhaps simply to visit specific dive sites below 18 metres/60 feet.

 

The Deep Adventure Dive will satisfy some of this curiosity and give you access to some of those dive sites by qualifying

you to dive as deep as 30 metres/100 feet,in conditions as good as or better than those in which you have training and experience.

 

 

 

Have you ever wondered why a jetliner cruises at 10,000 metres/35,000 feet

while a two-seater prop plane hums along at only 900 metres/3000 feet?

A jetliner has to fly up where the air’s thin enough to reach the high speeds necessary for crossing long distances quickly.

It doesn’t cruise up high “just to go up high.”

Deep diving is similar. You don’t make a deep dive just to go deep,

but as a means to an end. Deep diving gives you access to new dive sites that lie below 18 metres/60 feet,

and allows you to extend some of the activities you enjoy to new depths.

 

Through deep diving you can observe aquatic life that doesn’t live in shallower water,

visit wrecks that rest in deeper water, as well as shoot photographs.

In some places, deep diving makes it possible to drift effortlessly past deep water reefs (for more information, see the Drift Diving section),

and in other areas, you might collect or recover objects that were lost in greater depths.

 

Those are just five examples of the many possibilities when making deep dives.

  

 

 

In planning a deep dive, you must determine an appropriate objective.

An appropriate deep dive objective will usually be singular because you have less no decompression time as you descent.

 

It’s a reasonable objective, too, such as participating in one of the activities listed above,

and it’s based on your training and experience as well as dive conditions.

An inappropriate deep diving objective is one that expects to accomplish too much in one dive,

or for nothing more than the “thrill” of facing risk.

 

It’s not unreasonable to deep for the challenges and expands your training and experience to greater depths –

that’s what the Deep Adventure Dive and the Deep Diver courses are for –

but to simply plunge into deep water without regard for appropriate procedures is neither reasonable nor prudent.
