OK guys... thanks for the interest. I'll get my photos together and give some more info soon, but it's really nothing all that unusual. |

Before we broke out the scuba gear, we had to practice buddy-breathing off one snorkel. It was actually harder than buddy-breathing off one regulator since you had to have enough breath to blast clear the snorkel. Good Dives, Charlie OK, I have heard of that... I have also heard of divers having to do push-ups with their tank on their back... IMHO, those are silly (just my opinion). I don't really see any practical purpose of some of those exercises. Maybe, and this is just a maybe IMO, you could say it would give some "in water" confidence exercise. There are lots of those. I came from the era of "harassment training". When I was 14 years old, that was actually fun.  I still see some value at surprised mask removal or mouthpiece removal, but I can also see how it did get carried away into some excess. Luis, I agree with you 100% . I endured harassment as part of training, as well as many other macho exercises. I never included those in the courses I taught. I tried to make all exercises relevant. When my students did doff & dons, I explained that it's very unlikely they will have to remove their scuba unit during a dive, but it was helpful to familiarize them with the equipment. I also encouraged buddies to assist if needed. Good Dives, Charlie |

Luis and Charlie,
I went through the U.S. Naval School for Underwater Swimmers in Key West, Florida in 1967. We had pool harassment. Here's a short discussion of it in my manuscript (which I'm actively trying to get published):
In my first dive course, by LA County Instructor Roy France, our graduaton pool exercise was to get out from under a gill net that he put over the top of us as a buddy team. My girlfriend, Elaine McGinnis, and I were buddies, and we had to untangle our scuba for each other and get out from under it. It was a good exercise in how not to panic and to help each other underwater.
Now, I have done a doff-and-don underwater, and made a YouTube video of it.
John

My girlfriend and I did something similar, but we were only tangled under the sheets…
Oh wait, that is a different story… never mind.

After diving vintage style in low vis with a questionable hot rod double hose regulator last week I think I may start carrying a snorkel with me again. Not sure where I will stow it, but still not likely on my mask. Reg didn't fail, but the thought was there all through the dive. You could always carry it tucked into the waist strap on the harness like this guy. .jpg) |

I usually have a snorkel on either my mask or my helmet (with it's GoPro on top too). I river dive, and getting to the surface is not a problem. I remember two dives in particular where the snorkel came in handy. I was diving my Dacor Nautilus CVS, which had a slight leak, and could not use the J-valve on it (with the Nautilus it isn't reachable). So I mistook the reading of my computer, as it was showing almost out-of-air. Well, it did go out-of-air, and I simply surfaced and switched to my snorkel. Getting out of the water was a slower process, as I could not "blow" the Nautilus' chamber of water, and needed to lift it out of the water and let it drain. The second was a dive I had (second lamprey dive) where I was filming until I ran out of air with my twin 40s, tripped the J-valve and then simply surfaced and snorkeled to my take-out point. You can see this in the latter part of the second lamprey dive below. You don't have to watch the entire video, just go toward the end and watch. When I was in the USAF, we did parascuba jumps and would tuck the snorkel into our leg knife straps. Below is a photo of the three pararescuemen who jumped on Gemini VIII. Note the snorkel tucked into the dive knife of the PJ on the left (A//2C Glenn M. Moore, and the snorkel mouthpiece on the leg knife on the PJ on the right (S/Sgt Larry D. Huyett). A/1C Eldridge M. Neal is the middle PJ. Also note the two Mk 13 flares taped to the Glenn's knife sheath.  142720099_191814152628614_6615637713269724809_o by John Ratliff, on Flickr John |

John, thank you for sharing the photo. I enjoy seeing the copious amounts of original duck tape being used to hold rigs together.

John, thank you for sharing the photo. I enjoy seeing the copious amounts of original duck tape being used to hold rigs together. It's not duct tape, but rather masking take. With duct tape, you could not access the flares and other things. We even put masking take over the manifold protection to keep risers from getting caught on the manifold/regulator during the jump. Jumping out of the HC-130 meant jumping into the prop blast of a turboprop engine, and it sometimes flipped us in almost unimaginable manners.  142309158_5274939835851296_4955705790799075275_o by John Ratliff, on Flickr This is Eldridge Neal in the door of a HU-16B Albatross amphibian, from which they jumped onto Gemini VIII.

I have owned the Zodiac Super Sea Wolf since the early 1970's. It was the only decent dive watch I could afford as a high-school student working in a dive shop. I quit using it decades ago, but I still have it and it works great. I keep it in an automatic winder that regularly rotates it to wind it up. The watch is a beast... good to 75 ATM... I wish the bezel didn't look that bad. Replacements are not available. There is company in California that will service this watch, but they told me that they can't do anything about the bezel.
The scratches on the glass look much worse on this close-up picture than when I look at them.
BTW, the new Zodiac company is not exactly the same, but I am very glad they started making a reproduction of this classic vintage watch.
Thanks  |

Thanks for sharing. Good to know about it being not the original company.

Hi Luis! Hey, have you ever thought about printing your own sticker/decals? Just thinking out loud here, but... what if you printed some up on a laser printer and sealed the surface up with some kind of clear enamel to make it water proof? If you give me the specs I can probably recreate a printable image for you to play with... Just a thought? Jaybird |

That is a interesting thought. It looks like it can be refurbished. I appears that there is clear coat on top of the enamel of the ring. The crystal can be done with glass polish from a stained glass supply shop. At any case it appears that is does not owe you anything and has served you well.
