Unorthadox No-Limits dive with seemingly poor equalization technique:


Who am I??

Freedivers are often misunderstood by society and this can lead to some tough internal soul-searching to find an identity.

This reality is well portrayed in the documentary below:

Neckweights

In order to achieve neutral buoyancy and a good long glide, we need to compensate for all of the air in our lungs.  The easiest / most common way is with a neckweight.
The most "popular" method is by filling an inner tube with lead shot and is detailed here:  http://enjoyfreediving.com/2011/03/06/making-a-freediving-neck-weight/

I think this method sucks.

It is not adjustable, is fragile, doesn't allow for good hands-over-head streamlining and is a pain in the butt to construct.  I prefer using 1/2 lb lead "chicklets" and 25mm webbing instead.
They are not always easy to find and sometimes are uncoated as in this picture or come dipped.  The one above was dipped in blue rubber that I peeled away so that you can see the size / shape better.

Once assembled, you can add / remove 1/2 lb increments if your buoyancy changes over time.

For me, I have several neckweights.  One that works for full inhale, one for full inhale with max packing and one for depth work.

My depth neckweight is a very specific length, so that once inverted it falls over my chin and reminds me to keep my chin tucked in, so as to avoid a trachea squeeze.  It is also of random colours that were available at the time.  I am not trying to make a fashion statement with it:
I have used electrical tape to add 3 more chicklets to the outside of the main row, for added weight.  I did not tape the rest of the neckweight (to hide the colour) because I need to travel with this weight and the flexibility comes in handy, as it will be tossed around in luggage, etc.

My pool neckweight for packing is a thing of beauty.  I love this thing:
Looks a little more badass than the watermelon themed depth one above.

To get the appropriate weight needed, start with say... 4 - 5 lbs and have a friend watch you in the pool (you do have a buddy, right??).  Take a full breath and push off from the wall and hold the glide until you stop.  You will be able to determine if you need more or less weight and where to distribute it based on if you sink or float... and what parts of you rises / falls.

Most men can get away with just a neckweight, while many women may also need a little lead on their hips / belt.  I use the same weight on my neck and adjust what is on my belt to match the suit's buoyancy that I am wearing.  If I am not wearing neoprene or just a skin I will wear just the neckweight and forego anything on the belt.
