Demo Day

Try out CCR Liberty

Dear Instructors,
We have recently seen an increased demand from both potential and existing customers who would like to test dive a Liberty unit.

In recent years, every DEMO event we have organized or participated in has been a great success, resulting in subsequent sales and providing an unforgettable experience for our customers.

We therefore see strong potential in offering customers the opportunity to try our units. Many divers want to experience closed-circuit diving regardless of their current level of experience. Others may already be CCR divers but are considering a different brand or configuration. Even if some have seen our units before, there are aspects that can only be truly appreciated while diving, such as the work of breathing, the comfort of wearing the unit, the user interface, and the overall operation of the device. Experiencing these first-hand leaves a lasting impression on any diver.

These events also help customers get to know you personally and feel more connected to the Divesoft family.

At first glance, organizing such an event might seem complicated. However, as we want to stay as close to our customers as possible, we aim to simplify this process and make it easier for anyone to have the opportunity to dive our units. We would like to work closely with you to organize DEMO events more frequently.

We’re sure you remember the very first time you tried a rebreather - and the brand it was.

Based on our experience in organizing DEMO events, we have prepared a guideline to help you easily plan your own events.

Divesoft will also help promote your events through our social media and website, and we can provide additional support such as marketing materials, merchandise, rental units, and more.

We strongly believe that by hosting more DEMO events, we can build a stronger bond with our customers.

This will also help you boost your unit sales, expand your customer base, and create opportunities for sales of our other products as well.

Please find further information below.

Event graphics

We will prepare a unified event invitation graphic for you, consistent with the official Divesoft event branding. More details here: https://www.facebook.com/divesoft/events/

Each event will also be promoted by us on Facebook within the relevant locality. When posting on our Facebook events page, we will mark you as the event host (personal or company profile).

Merchandise

Please inform us about the size of your planned event, and we will prepare a basic merchandise package for you, which we will send free of charge.
Each guest will take away not only a great diving experience but also some nice promotional items.

If you would like additional promotional materials, please visit our e-shop and the Merchandise section.

Documents

It is necessary for each guest to sign the following document:
Liability Release and Assumption of Risk Agreement

Site selection

The site must have pool conditions. This means the following:

Water

Open water. If the site includes a cavern or other area with an overhead environment, this area must be clearly marked and not allowed to be entered.
Limited site area.
Temperature min 15°C.
Absolutely no current.
No waves.

Depth

Limited bottom depth with a maximum depth of 15m.
Depth at the entrance max. 1.5m.
Non-calcareous bottom.

Easy access

Easy access to the water to allow for comfortable entry and rigging on the shore or in the water and, most importantly, to allow for a quick retrieval of the diver in the event of a rescue. The entrance must be free from obstructions or dangerous objects and animals.

Visibility

min 10m.

Minimum requirements for divers

Minimum requirements must always be met, but may not always be sufficient. Further, the instructor will make the final decision based on experience and judgment of the applicant if, or to what extent, the diver can complete a demo dive.

Diver

Completed basic certification (OWD, etc.).

Minimum of 18 dives.

At least 1 dive within the last 6 months.

Crew

A minimum of two persons, including at least one instructor and one surface support person to assist with entering the water, setting up and sanitizing the apparatus.

If the demo dive is run individually for a single diver, only an instructor is required.

Equipment

Required & Recommended equipment

Required

CCR Liberty unit in the appropriate configuration.

All demo units except SM must have a BOV.

In the case of FMCL, the OPV must be in the open position.

Diluent must not contain less than 20% oxygen.

Bailout tank for diver is required only in case of SM. For all BM configurations, the BOV can be switched to a diluent bottle. In this case, the instructor is responsible for the bailout.

Disinfectant and loop disinfectant lavatory (not required for single client).

KPCR equipment, oxygen and basic pharmacy.

Basic tools and spare parts for CCR service.

Briefing

If the conditions are right, the briefing can be done in bulk for all participants at once, which can save a lot of time. We will brief the divers on the principle of CCR and demonstrate its basic elements. The emphasis is on introducing the BOV or DSV in case of SM. We will reassure the diver that CCR diving is very safe, but it is necessary to know the most basic rules, which are different from OC diving. The diver must be familiar with the following facts before the demo dive:

1. Mouthpiece

The mouthpiece must be closed whenever it is outside the mouth or the unit will flood.

Show divers the closed and open position and require several dry tests. Also, dry test the entire process: inserting the mouthpiece into the mouth - opening - breathing - closing - removing from the mouth.

During the dive, especially when surfacing above the surface, it is necessary to check consistently, as divers are not used to this from OC.

2. Bailout

In case of any doubt or discomfort, the diver can go for a bailout. Demonstrate on dry land how to go to bailout. Divers must demonstrate bailout skill on dry land. Supervise the correct and safe execution. This will also be the first and only exercise divers must try when entering the pool.

Demonstrate the bailout signal to the divers. This will be used in the event of an exercise at the start of the dive, or if the diver is threatened by something, to force them to bailout.

3. Loop volume, ADV and MAV

We do not aim to teach the diver the optimum loop volume, but it is extremely important that divers know the function of the ADV, MAV and overpressure valve.

Reassure the diver that if he should feel a small amount of gas restricting his breathing, or that he cannot breathe at all on descent, just add gas using the MAV.

Check that the ADV is open before the dive.

4. Surfacing

Make the diver aware that his breathing will not be affected by buoyancy. Breathing during the dive should be very easy and should make no difference to normal breathing on dry land.

It is important to point out the need to exhale out of the loop during ascent if they feel they have nowhere else to exhale. This is different from OC. Usually the OPV will solve the problem before the discomfort occurs.

During emergence, the diver must proactively control buoyancy by venting the BCD and exhaling outside the loop at the same time.

5. Control of ppO2

Show the diver where the ppO2 is on the display, how it appears on the HUD, and what range the readings should be. This is basically informative, as the main control of all instrument functions is up to you, the instructor.

6. General Instructions

Coordinate general diving signals with the diver. Determine the maximum depth of the dive, the duration of the dive, the area in which you will be moving. Reasons for ending the dive.

Performing the dive

1.

Perform a pre-jump check
a. Open cylinder valves
b. Switched to Dive mode
c. PO2 corresponds to setpoint
d. ADV open
e. BCD inflator available
f. Dry suit inflator connected

2.

Provide safe entry into water with a maximum depth of 1.5m.

3.

Carefully check the BOV/DSV closure.

4.

Attach one of the handsets to the on-board bottle so that you can see it and have an overview of all the functions of the device throughout the dive.

5.

Have the bailout controller ready so that it is immediately available to the diver in an emergency.

6.

Practice the bailout situation with the diver just below the surface.

7.

Do not let the diver out of your sight and maintain a maximum distance of 1m.

8.

Maintain the same depth as the diver.

9.

Be prepared to assist if the diver has buoyancy problems, or support the diver and adjust the buoyancy slightly.

10.

Ensure safe emergence and exit from the pool. Assist the diver to remove or coordinate ground personnel.

11.

Conduct a debriefing in which you evaluate the dive and give the diver space to express his/her impressions.
