See if anybody will go for it and we may share hotel/campsite.
I heard it from a friend in east coast who took it a few years ago who
improved his bottom time from ~1 minutes to 2.5 minutes with the help of
this course.
Almost 100% of the online reviews suggest it a productive course. In my mind
, it should be a must to go course if you want to do some serious
freediving/spearfishing to improve safety awareness and performance.

some ppl, like me, do not need to pinch and blow in most cases to clear the ear. I use a way similar to swallowing to open it up as frequently as I need.
btw, you need to equalize the ear and mask with your single breath of air.
a low volumn mask is prefered for freediving due to this reason.

It gets neutral buoyancy at 15 ft or deeper.

看来要逐步练习适应才能逐渐增加配重
BTW你配重哪里买的,我附近几个店看了都好贵

发帖数: 1327 | 8 This depth is where shallow water blackout typically starts to happen. the
diver should maintain positive buoyancy to float up if something bad happens.
I got the weight from local dive shop. A set with new weights should be
around $35 for SoCal condition?
