Description

Learn to Scuba Dive like an Explorer Today !

Scuba Diving is an exciting and adventurous activity, that allows us to explore the magic underwater environment.

Efficient and capable divers can minimize the risk through proper and innovative dive exploration procedures. Dive Explorer Foundation (DEF), an IDREO affiliate, has create a single and unique Scuba Explorer Course using the latest scuba diving techniques and technology available today, based on decades of worldwide dive training & Exploration.

Of the main objectives during the DEF Scuba Explorer course is for non-divers to become truly independent and knowledgeable divers, respecting the environment and with safety as the most important goal. 

DEF Scuba Explorers don't touch the reef or sand, we never kneel down on the bottom of the dive site to learn/teach dive skills, advanced training techniques and superior dive equipment design allow our divers to enjoy the underwater environment with minimal impact and perfect buoyancy. A key feature in DEF scuba diving standards is the "Out of Gas" procedure, as we donate regulator from the mouth and switch to backup regulator in a necklace, just as explorers do..

Find out what it takes, get your Academic portion done and the join the in-water portion with one of our worldwide recognized Instructors in Asia, Europe or America.

Who is the target audience?
  • Public in General wishing to explore the underwater realm
  • Divers interested in advanced diving techniques
  • Divers interested in sidemount

Dive Explorer Foundation, DEF, is the response for NON divers wishing to join the underwater real exploration independently and eventually join IDREO activities.

DEF, promotes single tank sidemount configuration, based in decades of technical and aCave diving exploration techniques and procedures developed by IDREO explorers.

Scuba Explorer training is the only course in the DEF curriculum, where the goal is not making you an OW Instructor right away but a reliable, capable and safe Open Water Explorer.

This training is ideal for boat owners whishing to go Diving unsupervised in any Open Water enviroment, while under a vast variety of conditions, such as current, night, deep, cavern, wreck and diving Nitrox mixes.

Pressure is exerted by the atmosphere and water to the Diver, is very important for any safe diver to understand the basic concepts in order to make educated choices interacting with the underwater enviroment.

One of the keypoints in making a succesful and flexible Decompression strategy is to repeat use between a few gases, as in Standard Mixes for standard applications such as Bottom Mixes and Deco Mixes.

The Standard Mixes should respect parameters reflecting the risk the diver and team agree to cope with, specially in O2 parameters and Narcosis. However is no secret nowdays that "Deep Air " risk is not only Nitrogen Narcosis the "real danger" of breathing Air at depth below 30-40 mts is Oxygen Toxicity the real enemy, which opposed to Narcosis will make diver convulse and loose conciousness. The Oxygen limits applied by IDREO are min .40 PO2 in any RB operation, perferably below .7 and Max 1.0 PO2 at any bottom mix portion of planned dive, 1.2 PO2 on below 90mt deco or short deep exposures, PO2 1.4 on "Deep Deco" or brief NDL dives, 1.6 in 21-6mt deco stops and PO2 2ata inside habitats.

The Explorer don't have necesity or willingness to high level of Narcosis while driving DPV's, monitoring Rebreather's breathing mixes & gases, navigating thru overhead tunnels, survey activities and/or research activities, so the Mixes Narcosis level are limited to 30mt/100ft max.

Gases identification in water is

strictly by MOD, however Background of MOD can also add the color

codes, notice that monitoring PO2 thru digital gauges in RB is required

during training and IDREO projects.

A solid Dive Plan is paramount in diver safety, but also critical in achieving dive goals.

The Dive Plan simple touches all the limits the team has for a given dive and

also underlines a "LIMIT LINE" when turning around back to surface should be happening.

Remember in a good plan limitations are hardly ever reach simultaneously,

so this mean you may have to call the dive on gas, time, depth or anything else,

so don't expect all Dive Plan limitations to happen together.


Divers should consider calling the dive anytime reaching ANY of the giving limitations.

When discussing Bailout we are talking as the back up plan to get out of trouble, in diving the worst possible scenario is sharing gas from the furthest point of penetration.

Proper Bailout is enough quantity of gas to make a OOG scenario work from furthest penetration point back to the surface, divers require to be able to make acurate estimations of gas need, plan adequate redundancy for further failures and be able to handle the bailout carrying options such as double tanks, stages bottles, deco bottles, multiple scooters and DPV's maybe be need to make the Bailoutfeasible.

Variations of Bailout are Minimim Reserve and Rock Bottom with basically same deifinition but applicable to specific situations such as a direct ascent to surface vs tunnel trael prior the ascent.

Indentify the Bailout calculation criteria and the options divers have in order to provide this important safety feature to all planned Dives

NDL stand for NO DECOMPRESSION LIMITS,but thruth is there is not such a thing as we relay on ascent speed, 10 MT / 30 FT per minute or if you wish 20 second stops each 3MT / 10 FT so to explain.

NDSL may be more accurate and stands for No Decompression Stop Limits, which are the minimum times a diver can stay underwater at a given depth before having to perform actual decompression stops before surfacing, so pretty much a direct ascent to surface, as long as respecting a defined minimum ascent speed usually 10mt/30ft per minute.

NDSL Times varies with depth and therefore flexibility in figuring out the times is key in manging efficient and safe exposures.

IDREO offers an easy and accurate rule to "on the fly" been able to figure your NDSL, while at the same time build up the skill need to manage the flexibility exploration diving will require. Notice the plan dive is not always possible to know ahead of time or can change dramatically without expecting it while underwater.

In short 120 rule.

Standardized Hand Signals make extremely fast and accurate comunication while underwater, without having to Stop and write down what is going on in your wetnotes. Wetnotes are mostly used for Data gathering.

Repetitive task are best served by a specific set of Hand Signals, notice gloves or to slow or fast movements make create complications when aplying Hand Signals for communication.

Expert Divers use lights not only to look around but for efficient communication.

Light communications
is both Active & Passive.

The Diving Bottles choices available for carrying efficiently the different gas need during a dive are very much define by material and size but also a keypoint is the configuration options.

All divers must be reasonably educated about Basic Diving Equipment function and operation as well as periodical maintenance.

The Basic Diving Equipment is Open Circuit and is a redundant (back up) version of the traditional Single Tank Diving, the extra components greatly increase diver task loading if not properly configured.

We should strive to bring only what we need for the dive, making sure we don't leave nothing we need behind but more important we are not dragging stuuf we don't need. Owning a piece of Basic Diving Equipmentdoes not automatically means we have to take it.

DEF OW Sidemount configuration is solid foundation to explore the underwater realm, it's minimalistic approach allows the diver to efficently move underwater due to minimum drag.


This is the DEF Scuba Explorer main recommended configuration for Non Divers.


The DEF OW Sidemount configuration is based in a back plate with a solid one piece webbing strap.
