Silt avoidance has more to do with buoyancy control, then finning technique, and I think I have adequately answered that. However, one more reason to avoid stirring up the bottom would be to prevent enemy detection. Although most ports are so murky you would lucky if you could see your hand in front of your face
Thanks Jeff. Your post was very informative.
I disagree here a little though. If you are very close at all to a silty bottom finning technique will make a big difference. A full flutter kick or any kick that propells water down will cause sitling and that's what the IANTD evaluation form is refering to but all else being in good order it's not something that takes long to learn.
If the diver were going to go to 30 feet we would not be using a rebreather at 100% O2. For deeper dives a SEAL would use either a MK15 or MK16, which is a mixed gas rebreather.
I didn't know how deep they used pure O2. I thought I read somewhere it was 2 ATA but you know better than me. We of course cut it off at 1.6 and only use that for decompression.
They wouldn’t have been graduates.
I'll take your word for it.
Because you’re basing your conclusions on a small and misrepresentative picture of what is included or not included in our training. In addition, due to the fact that you have never personally experienced it, or even seen it in its entirety there is no way that you can be objective.
The only conclusion I have made was limited to what I saw. I thought I clearly defined the scope of my comment in like my very first sentance. I, of course, realize that what I saw was a small picture since the show only lasts like an hour. You're stateement as some one who's been through the training that it's misrepresentative is also helpful. Easy enough to believe since even the new reports often are.
I'm not sure why the Navy would allow the filming of the training or what their goal was. I don't know what impression they want people who see it to come away with. I can tell you that there were two other cave divers and a new OW diver present for the viewing. Being divers, we looked at the diving and you already know what we saw and thought. The film makers obviously wanted to impress us with the phisical abuse and difficulty of the training. Since the show centered on dive training they might want to think about showing some of it to give a more accurate representation. Maybe the Navy doesn't't care and maybe they just shouldn't let the camera crew in.
I'm also a farrier. I've had horses knock me through oak plank walls, rip holes in my flesh with their teeth and send me flying with a good solid kick to the chest. However, if I was going to produce, or allow, the production of a tv show using me that was meant to show the public something about the trade, I would show something other than me flying through solid walls because it just doesn't provide any information other than horses sometimes abuse farriers. LOL
Mike, if you have anymore questions that I can answer or have not answered, then send me a PM, and I will give you my phone number.

Again, thanks for the informative post. Based on what you wrote I don't know why all the agencies don't recognize military dive credentials. I would think that would be something they'd straighten out for you guys without making you pay for a card from a rec agency.
I don't need an OW card if I have my cave card on me. Why would you need an OW card?
