Hey James, off topic here, but wanted to comment that it is nice to see Jeff on one of your videos! He took my dive buddy and I on our first two dives on the Spiegel Grove last December. Not having a lot of experience in rough seas up to this point, I was definitely nervous about the waves (4 - 5 foot) and current. Jeff was super chill and reassuring - did a great job getting us in and down to the wreck. My jitters immediately disappeared. That first glimpse of the Spiegel as we came down the line just rocked my world. Love that wreck! Thank Jeff again for a very cool introduction to that wreck. We went back down to dive it a couple days later and had an absolute blast. Can’t wait to come down to dive Spiegel again!

I am a technical rebreather diver, I’m certified in the O2ptima CM. It’s not just a recreational ccr. It’s a full-fledge technical rebreather. Just commenting on the beginning of the video.

So correct me if I'm wrong... The frontmount CCR is optimal for using with a regular backmount tank or twinset (or even sidemount) because like this you don't have to change anything in your standard dive gear. The cylinder on your back takes the roll of the bailout that any CCR diver has to carry and at the same if you want to dive with open circuit, you just leave the rebreather on the the boat. Also it could be possible to donate the rebreather to another diver if the situation requires (of course someone with proper training and according to specific dive plans) So this CCR becomes a very flexible tool!

Depends on the unit. I carry more weight with my choptima because the unit itself is light but has a decent size counter lung volume. Since there is a new air space you now have more buoyancy. In a dry suit, with sidemount steel LP50s and a chest mount rebreather I wear 8lbs of lead. Doesn’t seem like a lot but I’m already wording two steel tanks ;) When you have the super bulky units like the inspiration and revo and backmount optima..they have large metal stands and other heavy bits, so weight is typically reserved for trim on those.

Hi Thomas W. In warm water, diving a single AL80 like James was in the video, I typically add about 4 lbs to a student. Once you get use to diving the unit, and control over the amount of gas in the rebreather that can drop to 2 lbs. Switching to a steel tank can also do the job ;) Great question!

I have a stupid question, why do you tend to dive with your arms extended in front of you and you fins upward. I have seen you do that in other videos. I can guess the fins is to avoid them accidentally touching below you and you bring them horizontal when actually moving or are their other reasons but I am less sure why your arms and hands are in front.

It's a very stable position. Having your hands in front is the standard position in technical diving. The skydiver position helps maintain horizontal trim by tensing your body, allows you to hold your light (which isn't optional for technical diving) and allows you to signal clearly to your team. If you're wearing a dry suit it's even more helpful for trim because you can trap some air in the arms and for venting gas from the suit since the dump valve is on the upper left arm. The legs are bent that way to keep the fins from the bottom where they'll kick up silt from the bottom. The frog kick, modified flutter kick, helicopter kick, etc. all start from this position and are commonly used by technical divers.

Hi. I'd like to ask, is it possible to use it with dry suit? I mean, on dry suit, you have inflate valve on your chest. Thx

The small one in front a pure oxygen, a chemical reaction removes the CO2, the remaining gas is then measured for oxygen and a small amount is added from the small tank in front. As you know air has very low amount of oxygen, so most of what your expel is nitrogen, normally that is wasted, this unit just recycles is along with a fresh supply of oxygen and any unused oxygen. Only a free diver ever actually uses all the oxygen, most of the time to exhale more than you take in. In fact you passive breathing is much more effective than controlled breathing so relaxing allows you to absorb more than puffing away.

The extra bottles in the back are called bail out. As with all scuba equipment rebreathers can fail. If they do, what will you breath? Bailout!

@0nBe1ay

2 жыл бұрын

Hi Cristian. All CCRs need two gasses. Oxygen to replace the Oxygen your body uses, and a leaner gas mix to take up space and be able to lean down the Oxygen to keep it from rising to toxic levels. The leaner mix is called Diluent, and can be anything from Air, Nitrox, or Trimix. Most back mounted rebreather will have those bottles mounted with the unit on a divers back and they tend to be small 3L (23 cuft) or smaller. Because the Choptima is chest mounted, it opens up options for where those bottles can go, and the size of the bottles. Rebreather divers also need to carry enough gas to get them back to the surface without the rebreather, in case it fails, and that gas is called a Bailout. Depending on the dive this could be a 40 cuft bottle of air, or several tanks of various mixes for staged decompression. In the video James is diving a single AL80. He has a small bottle on the bottom of the Choptima that is for Oxygen, and the AL80 is his Diluent. Hi AL80 is also his Bailout since we were in 30' of water and not doing any decompression diving it is a pretty ideal setup for the dive. I typically dive my Choptima on deeper dives which will require staged decompression and thus more gas. My left bottle is typically 21/35 (O2 / Helium), and my right bottle is 32%. I can bailout to either less than 130', or have them both for deeper dives. The majority of my dives are in the Hope that helps.

@@cristianconrads9109 as you'll learn with OC technical diving, with CCR you've got to do a bit more dive trip planning before booking a trip. Recreational destinations may not be equipped to support technical divers. Either with fills, tanks, or equipment. They may not even allow doubles on boats. Some places may allow technical dives, but not support them. And some may only support OC divers but not CCR. Typically I don't travel with any tanks. I get them at the destination...unless I'm driving there, and then I bring as much of the dive shop as I can. When I choose a destination, or trip, I go specifically to places that support the diving I'm planning on doing. DiveTec in Grand Caymen, Horizon Divers in Key Largo, Buddy Dive in Bonaire & I'm pretty sure TDS at Capt'n Dons is up and supporting CCR now too, are all examples of full service and support CCR dive shops. A lot of CCR divers and instructors run trips, or lead dives that are organized towards CCR divers. Becky K. Schott, Pete Mosley, James Blackman, and Horizon Diver in lovely Key Largo Florida ;) are all great trip leaders for new or experienced CCR divers. And they all go to some pretty sick places. When you get done with your Deco Procedures, shoot me and email and I can totally point you in the right direction for some great diving, or trips to all the cool places.

For new CCr divers who aren't already certified technical divers the first course, Air Diluent / No Decompression sets you up to get a good base of experience with a max depth after certification of 100' (33m) and limits you to your No Decompression Limit. After 30 hours / 30 dives on the unit then you can upgrade to Air Diluent / Decompression.
