isn't it better to go down more slowly to give your ears time to adjust to the change in pressure...If you can hold your breath for that long I would do down slow (saving energy too) and thus give your ears time to adjust....I know if I go down below 10 feet my ears bother me too much.
going slow doesn't help equalizing as well as stopping doing a valsavla maneuver and continuiing down...

Yeah, if you learn to pop your ears quickly on demand, you can dive about as fast as you can swim.

Damn, 18 feet? I can't even dive more than 8 feet due to the pressure on my ears. It hurts like a sonofabitch.

Get better at swimming first if you think 18ft is a stretch for a free-dive. Back when I lived in The Keys I was up to about 30ft, but I spearfished with some friends who could do 40-50ft (granted, using fins).
If equalizing gives you trouble, take a non-drowsy anti-histimine an hour before hitting the water, it'll keep the "squeeze" away. I usually do 5min or so of regulated deep breathing before any chore like that, helps to get as much oxygen in your bloodstream as possible before working on reserves.


Watched a friend of my dad's retrieve a stuck anchor one time with a 54ft free dive. That guy was baddass!

So fart on the way down, and eat a bean burrito on the way up.

18ft is a piece of cake when you can hold your breath for over 2.5min like me ;)
I once blacked out at a little over 3min. Luckily I was being spotted by a couple people. and was pulled up. Free diving is my life. Also am a Certified Diver but anyone can do this.
Tie a piece of rope to a bag that will hold the brick. Dive down and insert the brick into the bag. Take rope to surface. Pull up bag.

We had to swim a mile in a ful flight suit in the Navy SAR program in under an hour (I think it was 72 laps in an olympic pool)

This would be difficult? What, are you blindfolded for this? Did I miss something and you're actually a 72 year old man?

18 feet? Just going upside down you're 1/3 the way there. And a 20lb brick weighs like 5 under water. :roll:

LMAO. I've been swimming competitively my entire life, and this task would be a challenge.

Practice surface dives. They're not too difficult. When you swim over the brick, use your arms to throw your head straight down into the pool...then allow your legs to straighten out so you can sink faster to the bottom. Kick on your way down and extend your hands until you hit the bottom. Once you grab the brick, boost your self off the bottom, but ascend at an angle so you can equalize the pressure easier.

we talking about muff diving here? (as Taj would say)

I can't get a watch out of 12 feet of water, I couldn't imagine doing that.

Kinda a radical idea. I heard about it some special forces training where they throw you into a 10 foot deep pool with your arms and legs bound and you need to cross the pool. The only way you can do it is by exhaling all your air out at the surface-which is completely counter to your instincts-and drop as fast as you can so you can get a strong push off the bottom and get to the surface for a quick gasp and then do it all over again.

So, try exhaling before you dive or, at least, not taking a deep breath.

I think it's a better idea to take as large of a breath as possible. The trip up, carrying the weight, will be the hard part. I think you'd want as much bouyancy and occupancy as possible. Swimming down with a full lungs seems easier than hauling a weight up with no bouyancy and no air.
