Freefall Feeling.....

6/12/2018

The freefall can be one of the nicest aspects of depth freediving. The moment on the descent when you become 'negatively buoyant' and start to sink independently of effort. This of course has it's advantages, most prominently; saving energy (and therefore oxygen) and aiding relaxation (saving oxygen and facilitating ear equalisation).
So what is involved in a good freefall? Let's take a look:

Correct weight: This allolws you to stop kicking at the correct point of the dive to start the freefall. Too light and you wont freefall early enough. Too heavy and you will waste energy on the ascent.
Body position: Tucked in (elbows and knees), legs together, looking ahead (not down), and relaxed shoulders and neck.
Equalisation: Remember to equalise! Use the movement of the lanyard or your fingers on the line to help judge the speed you are falling. Equalise frequently and before pressure is felt.
Turn: With the correct hand position to turn, the momentum of the freefall can mean very little effort is needed to make a smooth turn at the bottom of the dive.
.....and not forgetting..... The Way up!: Using POSITIVE buoyancy to finish your dive by stopping kicking in the last 3-8m before the surface.

Paralenz Camera Pt2: In Water Testing

4/7/2018

1 Comment

Those of you following One Breath Freediving on your social media channels will already know that I have been using the Paralenz dive camera quite extensively already, for both photos and videos, so for this review part 2 (part 1 is un-boxing and initial impressions),I wanted to look at it's use in the water. More than numbers such as pixels and frame rates, I wanted to discuss it's functionality and how well it works specifically from a freediver's point of view.

Firstly, it's primary mount method that I have employed so far with the Paralenz dive camera has been the mask mount. For me this has been the most convenient as I am normallly using it while teaching or guiding. Once the mask attachment is threaded to the mask strap, you clip the camera on using the 'T-Rail' mount system that gives a reassuring double 'click' when properly secured.

The first thing you notice while wearing it in the water is.....that you don't actually notice the camera! Despite feeling substantial and solid when held in the hand, once attached to the mask I can honestly say that I forget that the camera is actually there. Being so non-intrusive is a huge plus for freedivers as we take in the water minimum equipment and definitely don't like things that create drag or resistance.

Functionality from this position is another massive plus. The feedback loop of vibrations of the camera unit, mean that you do not need to remove the camera (and mask) at all to know what setting you are in! For example, rotate the selector ring clockwise while turned on gives one vibration for video, two vibrations for camera, three for settings etc. And then long or short holds of the activation switch can start or stop recording or offer other functions. This creates a simple user and selector operating system and excellent hands free usability.

Now lets look at the quality of photos that Paralenz is capable of (for videos, check the OBF YouTube channel). All the snaps in this review were taken from the mask mount position, so just a reach to the side of the head and a short pull on the activation switch can give you some great photos. While primarily a video camera, the photos are surprisingly clear, sharp and lacking in distortion at the edges (as can be common for extremely wide angle cameras). In these photos I had Depth Colour Correction (DCC) turned on and Depth & Temperature overlay turned on. The photo above from 5m displays nice blue water and clear white logos on the wetsuit hood. The first photo handles the reflecting light from the shallow water very well and also created a shot that is not blurred or distorted from the divers movement.

Initial in water conclusions:

Mask mount is very useful for hands free use
Unit vibration feedback is a great idea and super useful with mask mount
Photos lack distortion and are very sharp
DCC is perfect for multiple depth change diving (such as freediving)

Look out for part three of the test where I will review the features of the Paralenz App.

The Beauty of the Blue Hole

8/3/2018

1 Comment

There can't be many places as alluring and iconic to freedivers as the Blue Hole in Dahab. With imposing, barren mountains just metres from deep blue water and a kaliedoscope of colours amongst the corals on the reef with every shape and colour of fish possible, it is a truely beautiful place and draws freedivers from accross the world.
A natural submarine sinkhole, the depth within the hole is 100m and just outside, on the reef's edge, the depth reaches over 1,000m. A sheltered location and lack of current just metres from shore means that this is a wonderful place to train for freediving.

One Breath Freediving will be conducting a Training camp in in Dahab Egypt in January and February 2019. Enquire for further information.

Scuba Diver to Freediver: Pt.2

28/11/2016

2 Comments

The last few weeks I've been practicing my breathing with an app called STAmina. I was advised to follow the CO2 breathing sequence which will help build up resistance to the bodies natural warning of CO2 build up. I started on the app with 0:45 second breath holds, 1:00 minute breath holds, then worked up to 1:25. My breath holds are currently 1:25 and breathing sections starting from 1:30 and decreasing by 5 seconds to 0:55. It's 8 cycles and the total time of the exercise is 20 minutes.

One thing I noticed was that it was important to be relaxed with no interruptions. If I got interrupted then even at the first 15 seconds of my breath hold I'm thinking that I won't manage it, and towards the end of the hold it was starting to become uncomfortable. I had the app setup to beep every 15 seconds which seemed to help really well, as its difficult to judge how much time has passed. I've notice in the past that it can sometimes be difficult to judge time when relaxed. It currently feels good to know the elapsed time, but I can also see how it could be off putting as well.

In a few days I'll be in Malta with One Breath Freediving. So I need to keep up my breathing exercises and finish the last few pages of the AIDA2 manual.

Before doing any training I thought I may be able to hold my breath for 1 minute. But following the course manual and the breathing app I've surprised myself that I can do 8 cycles of 1:25 breath holds.

I'm a bit nervous about some aspects of the course. As a scuba diver I know I'm more comfortable and relaxed when under the water, rather than on the surface, so I'm currently wondering how well I'll be able to relax on the surface. I think of the transition between the surface and underwater to be the risky area when scuba diving..... probably due to possible kit issues rather than physical ability. Also, on the surface I feel more exposed and vulnerable and this only seems to be the case in the sea. Once under the water it's peaceful and calm.

Another issues is the feeling of being underwater on just a breath hold. Being at 15m without an air supply is very dangerous situation when scuba diving but is perfectly normal and safe when freediving. Although I held my breath when in a pool or snorkelling in the sea and felt ok

Scuba Diver to Freediver: Pt 1.

10/8/2016

Welcome to a series of new blog posts where we follow the experience of a scuba diver as he learns to freedive properly for the first time!
Here is part one:

I started scuba diving in September 2011 and have done 400 dives. I've completed the PADI divemaster qualification as well as the SDI Solo diver, PADI tec 40 and I'm currently studying for Tec 45.

I like to learn from every dive and always look at ways to improve. I'm currently working on kit configuration and practising technical diving procedures and methods. I've thought about doing a freediving course for the last 2 years, although I've not taken it any further than that.... until now. In about six weeks I'll be doing my AIDA2 with One Breath Freediving in Malta.

A couple of days ago I went to my local 6m deep pool where I was able to prepare for the course. I just wanted to practice The Frenzel Maneuver for equalising. This is how I equalise when scuba diving, but when scuba diving the decent rate is a lot slower and I'm horizontal, not head first.
After 15 minutes in the pool the equalising was going well and towards of the session I could manage 30-40 seconds under water. This was without knowing any relaxation, breathing techniques or how to efficiently duck dive. At this point I hadn't read anything about freediving. I used a 5mm wetsuit, 3kg weights, scuba fins and mask.

Over the next few weeks I'm going to be studying the AIDA2 manual and spend some time practising breathing and relaxation. I'll update my experiences here in a couple of weeks while I progress through the freediving manual.
