5 Useful Items for your Dive Bag (that could Save the day!)

24/6/2022

By David Watson, AIDA Instructor Trainer & Owner & Founder at One Breath Freediving
We all know the main equipment we need for a successful freediving session or to go exploring in the sea.  It's a pretty standard kit list: mask, snorkel, wetsuit, weights & belt, fins.
Maybe if you are an extreme 'minimalist freediver' you might go in the water with only a swimming costume and mask / goggles (see an extremely  impressive take on this in the video below!)
But in this blog post I wanted to share with you all 5 pieces of equipment I keep in my dive bag or in the car that could potentially save your freediving session:
  1. (Johnson's Baby) Shampoo -A cheap and little known way to keep your mask from fogging up. Apply inside the lens before getting in the water, and rinse out before putting on, to guarantee a clear view all session! This has saved the day for me or my students more than once after masks that should have been good after multiple treatments with the flame of a lighter, still fogged up.
  2. Fin Retainers - Cheap and small these can mean that if you forget your neoprene  socks you can still use your fins and dive. If someone else with smaller feet needs to borrow your fins they can still be used. I use them all the time as it gives a more secure fin fit and transfers more of the power each kick to the blade (See: https://massdiving.com/products/full_foot_fin_retainers)
  3. Emergency Whistle - Small and discrete I have these attached to all the buoys I use for teaching. Perfect to attract attention or give a warning in an emergency situation (See: https://www.ndiver-rescue.com/peeless-whistle)
  4. Mask strap - Can save the dive session if you mask strap breaks, and it will take up almost no room in you mask box! A must have.
  5. Lanyard - Even if not diving deep or diving off the line  I keep this in my dive bag. If used as a backup lanyard on a line training session it gives an option to secure bi-fins or monofin as they can be threaded through and kept secure when not in use (diving no fins for example). It also provides a spare carabiner that is always useful to have.

5 Tips For Using Paralenz Dive Camera

When the Paralenz dive camera was released it was a game changer for underwater videography as it had some extremely innovative and unique features and did not require an external housing. Those of you that follow the One Breath Freediving social media channels will know I'm a big advocate of this camera (both for teaching purposes and fun use), and I take it with me in the water as much as possible.

Now it has been on the market a few years and has evolved with newer versions being released, it is possible to buy the older versions cheaper or even secondhand, making this type of camera even more accessible to freedivers.

Here are my 5 top tips for using a Paralenz:
  1. Depth overlay feature: The overlay adds the current depth and water temperature to your videos (see still shots above) and updates constantly during the dive. This creates a visual record of where you are in the dive and makes your videos much more interesting to people watching them.
  2. Mask mount attachment: The mask mount attachment is a great item included with the camera package, and especially useful for instructors (or buddies) doing line depth training. Though not as ideal for higher quality video shots as the selfie stick, the mask mount allows continuous hands free use of the camera and is great for filming a student or a buddy so you can review the technique of the dive later on after the session (see top left still shot).
  3. Auto start / stop feature: As the Paralenz camera has a depth sensor, as we already discussed in #1, we can also set this feature to stop and start the camera filming. For example, if you set the camera to start and stop filming at 0.5m using the mask mount then it creates a truly hands free camera that you can simply turn on and forget about during your dive session.
  4. Paralenz App: Downloading the Paralenz app to your phone means you can review the footage straight after the dive while you are sipping your coffee :) Footage can be transferred easily and quickly via blu-tooth connection.
  5. Battery life: One of the stand out features of Paralenz is the battery life which can be 2-3 hours long on average! So make sure you don't cut corners by buying a cheap or small capacity memory card. With this type of battery life you can film as much as you like in the session without fear of 'missing' those passing dolphins that will no doubt appear at the end of the dive day when those other, inferior, cameras will be long finished.

AIDA Monofin Course: Training Drill

16/4/2019

1 Comment

 
Monofin Training Drill:
Here Jose is using a kick board to help stabilise the upper body and a front snorkel to allow him to breath during the training exercise. This takes away the 'apnea' element away from this particular drill and allows him to focus on technique over breath hold while he adjusts to using the full sized monofin.

​How do you think he is doing?

Freefall Feeling.....

6/12/2018

1 Comment

 
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

2 Comments

 
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. 
Picture
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.
Picture
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.
Picture
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.

Paralenz Camera: Pt.1 Unboxing & First Test

18/5/2018

0 Comments

 
I recently got my hands on the new Paralenz underwater camera. This powerful little package has been making waves (excuse the pun) in the underwater world. An action camera specifically designed for underwater use it has some really well thought out features and specifications.
​But I am getting ahead of myself! Let me start with the un-boxing.

The whole package of the Paralenz camera tells you it is well thought out and made for divers, by divers. Firstly, you can't help but be impressed by the included carry case that securely seats the camera and accessories, keeping them safely in one place for travel. This would always be an extra purchase with any other make of action camera. Secondly, inspecting the actual camera, it is shaped like a dive torch having a sturdy and substantial feel to it, feeling robust and of high quality  (it is made from aluminium). It also has a weight to it that gives it a great feel in the hand. 
Picture

Testing out the buttons and dials it has two main options. The selector ring (blue dial) is magnetic and allows you to select the main options (video, photo, settings etc) and the activation switch (raised, before the logo) allows you to select options and start/stop recording. Both have a smooth and distinct movement when used. ​In conclusion, the build quality is top notch.
At the rear of the camera, behind a glass window, is a small screen  that shows the current mode and battery / SD card usage as well as the charging port for the USB-C cable.​ This will be the most notable difference from other action cameras..... The absence of a screen for viewing video. But what would a big screen be used for? To centre the picture during filming maybe? But the field of view in this camera is so wide anyway, and with experience you will get to become a good judge of distance and framing. In the real world, large screens on action cameras were a battery draining luxury (who actually played back footage direct on their camera???)
The accessories included here set the standards high once again: two different mounts, grease, spare o-rings, case, lanyard.... All would be extras by other manufacturers. It tells you this camera has been thought about and the end user considered.
Picture

The camera uses a wi-fi link to a dedicated app. This is something new for me and as not the most technologically minded individual I was not sure how easy I would find it, but it was actually very intuitive. Once the connection was found I could quickly view and save my first underwater footage from the camera! (pond life, 10cm underwater, but hey, we have to start somewhere, right?!)
So what initial conclusions do I have:
  • Great package, well designed and feels very high quality
  • Nice extras included
  • Easy and intuitive to use
Very much looking forward to testing it in the sea! Coming soon will be part 2 of the test when I will use it for the first time freediving in the Mediterranean sea, Malta, and going in to more detail about the settings and underwater performance and hopefully have some nice footage to show off :)
