Arcticnick - ...Equalization tends to be the biggest issue at first - even scuba divers are not used to the speed and frequency needed for freediving - plus equalizing head-down is very different. As you get down in the 30 meter range you need to be mindful of lung squeeze. A lot of us do special exercises to help the lungs and chest adjust to negative pressure. Equalizing becomes a whole 'nuther below 30m too...
Bottom line there is no substitute for experience - which takes time. I'm sure the AT courses will give you what you need to do safe dives - best to go with an empty cup (insofar as thats possible!). Then you have to make it your own.
Hiya Fondue,
Thanks for your kind input.
It is good to start to understand some of the specifics that I can expect on my course, and my new chosen path.
I would really like some practical understanding of what I can expect, both with the theory, breath hold learning techniques, as well as the diving itself. The more detail the better...although I know most people have otherwise busy lives, and can't spend endless hours on a forum, here, each day.
I have put this post, below, in another part of the forum, too but would be very interested in your opinion, please.
Sorry if you have read some of this info previously, in different threads.
Hi there,
I have just come back from Thailand, on a snorkel live-aboard boat, for 3 days, 60 km off Khao Lak, Similan Islands.
I had a great time. So great, infact, that I am packing up my life in Swedish Lapland and heading back out there, in May!
One night, after the divers and crew went to bed, whilst sitting on the transom of our boat, Lee, our guide, and me, did one warm up breath- hold, two minutes of deep breathing followed by a hold, which was none too impressive.
Then we recovered briefly and did it again.
-I held my breath for 2:16 secs.
I then let out my breath in a very controlled way and took two more deep and controled breaths, and held it again, for a further 1:36 secs. (3:52 sec with 2 breaths?)
-I feel that was amazing for my first effort. Room for improvement but a solid start.
The last time I held my breath was over 30 years ago, in a French lesson, for 2:00 min!
I am planning to do some intensive freedive courses, maybe in Koh Tao.
If I take it seriously:
-I would like to know what kind of times and depths I might realistically manage.
I am nearly 47, in pretty good shape.
I have been doing long distance winter cycling, in the Arctic (minus 17C/ 72 kms and minus 22C for 1:45 up mountains etc, and gym workouts.)
I weigh 70 kilos/ 10% fat. Good muscle mass. I eat mostly raw fruit and veg, no refined carbs. Almost no cooked food.
-Please can you stick you neck out and give me some idea what depths and bottom times I might realistically aim for.
-What do serious divers, who complete their courses, and don't drop out because of injury...manage?
