- Electrical Diagram
- Mechanical Diagram
WARNING: It is assumed Diver has a minimal experience and Diving Knowledge, however as BONUS, update or review we have included a General Diving Knowledge in Section 3. You may want to get thru that first if you are bit rusty or beleive your knowledge is limitate.
- DPV Brief History2:55DPV's have traditional being interested tool for military applications, however researcher and specifically Cave Divers where the ones to quickly visualize a benefit and explore the possibilities of applying this tool to the diving missions.
Cave Diving participation on the development been key in the DPV History design, type , burn time need, which eventually develop in a mangeable more technically advanced unit able to be use by just about any diver.In this lecture you will get a clear progression of Diver Propultion Vehicles development, including diferent types and applications, which is quite interested education need when deciding to acquire your first DPV or if thinking in upgrading your DPV fleet. - DPV History QUIZ
- DPV Planning Sequence2:41A general overview of how extreme DPV dives are done is extremely important to plan efficient DPV dives, in this lecture let's have a look at how a 4km / 13500ft DPV Planning Sequence to perform a penetration in a cave is done.
The DPV Planning Sequence for a extreme long range dive, will require- Set Up Dives
- Push Dive
- Clean up Dives
- DPV Planing Sequence QUIZ
- DPV Math10:56
When Planning DPV dives and going thru the DPV Math you will quickly realize that beyond single scooter diving the gas need and bailout considerations between a very close relationship for the DPV diver.
Multiple DPV Diving commonly comes as a package with large quantities of Gas need and therefore thorough, accurate estimation of gas required to be able to achieve the need or planned burntimes, that will eventually cover the distance you are aimining to acomplish.
In this lecture we will go thru the detail of calculating- DPV Times
- DPV Gas
- DPV Math QUIZ
- DPV Basic Techniques & Skills5:00Video Uploading Soon !
In this lecture a detail explanation of the Basic DPV Techniques and Skills need to safely use Diver Propultion Vehicles.
Expect the following skills to be reviewd further in land drills as well as toroughly practice while in water training sessions at all IDREO DPV Explorer Classes:
- DPV Set Up
- DPV Driving
- Diver Towing
- DPV OOG
VIDEO COMING SHORTLY !
- DPV Set up3:06
Complete DPV Set up allow DPV divers to enjoy efficient DPV diving but also promote safe long term DPV operation.
Battery monitoring, maintenance and burn time prediction is paramount in safe DPV Set up.
Proper Tow leash attachments, buoyancy and trim are the basics in safe and efficient DPV set up
- DPV Driving Techniques1:34
The right DPV Driving Techniques combined with perfect DPV diver trim allow DPV divers to reach maximum efficiency.
Predictable burn times and distance estimations are easier to figure out when DPV diver DPV Driving Techniques and DPV diver trim are constant and dove at maximum efficiency.
- DPV Turning Techniques2:57
DPV Turning while submerge on the water requires specific techniques to avoid loosing speed and make effortless, even in reduce areas, changes of direction.
DPV Turning techniques are 45º, 90º, 180º and 360º, use to change direction of travel maintain team formation and or handle a run away DPV.
Efficient DPV Turning techniques are based in reduce drag and aggressive configurations.
- DPV Advanced Techniques ( Failures)4:00Video Uploading Soon !
In this lecture a detail explanation of the Advanced DPV Techniques and Skill need to safely use Diver Propultion Vehicles.
Expect the following skill to be reviewd further in land drills as well as toroughly practice while in water training sessions at all IDREO DPV Explorer Classes.
- DPV Failures
- DPV Towing
- DPV Flooding Recovery
VIDEO COMING SHORTLY !
- DPV Techniques QUIZ
- Basic Equipment Configuration12:00
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 Buoyancy Control Device and Regulator, 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 Equipment does not automatically means we have to take it.
- Dive Planning7:48
Dive Planing 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 a good plan limitations are hardly ever reach at the same time, so this mean you may have to call the dive on gas, time, depth or anything else, but don't expect all limitations to happen together.
So divers should consider calling the dive anytime reaching ANY of the giving limitations.
Dive Planning is by far one of the most fun parts of Dive Exploration.
- Bailout Considerations11:46
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 Bailout feasible.
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 vs NDSL4:44
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.
- Hand Signals12:00
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.
- Light Communications3:38Expert Divers use lights not only to look around but for efficient communication.
Light communications is both Active & Passive.
In this lecture we review Light Communications and Light Signals the goal is to understand them better to take the most advantage from using them. - IDREO RB Configuration8:28
IDREO REBREATHER CONFIGURATION philosohpy is build upon simplicity & consistency among all platforms, the goal is to dive all units with the exact same way of operation, independently of RB Types and/or mounting capabilities, while reducing diver task loading.
The obvious advantages are compatibility among divers and equipment, but extend to gas standardization and decompression mangement.
- Team separation Protocols1:46
Team Separation is a situation that is very easily dealt with, IF all dive team members stick to a protocol.
The Team Separation Protocol in Open Water is search for a minute and re-surface, get to gether in the surface and then dive again staying more aware of dive partner location at all times !
For overhead enviroment situations the Team Separation Protocol is the same but performed along the Main Line, exiting the overhead before been able to surface.
At surface/ Cavern wait for at least 5 minutes. - General Diving Knowledge QUIZ
