A good freefall is something that needs to be practiced and perfected over time and can make a huge difference in your dive time and depth reached.
Freefall begins with establishing neutral buoyancy and knowing exactly where it is. Neutral buoyancy should be at around 10-13m. Freefall should begin about 5-7m after you reach neutral buoyancy, so you are already adequately negatively buoyant before you stop all movement.
Here is a guide to help you improve your freefall :
- Give two final, slightly stronger kicks/pulls/one last arm stroke
- Keep your arms at your sides if you are using a nose clip. If you are using a mask, keep one arm tucked at your side with your elbow to your ribcage while equalizing.
- Slightly tuck your chin into your chest to aid in equalization and prevent against trachea squeeze.
- Slightly round your shoulders forward and relax your belly so that you are not keeping any tension in your upper body.
- Have your legs slightly bent forward at the hips, with slightly bent knees that will cause your fins to run parallel with the line.
- Make sure to open your eyes every once in a while throughout your dive to check line positioning.
- Make sure that when you reach the end of the line, avoid quick or jerky movements. Turn slowly and keep your head tucked in or in a neutral position to avoid any injuries at depth.
