What is so bad about ascending at 6m/min and not 10m/min. ? I was recently in a training for Trimix and the instructor was adamant about the 10m/min ascent rate, which I fail to maintain or sometimes even reach, my buddy had two Shearwater DC, and he was able to do better job on our practices...

I'm doing my Trimix course online before I go to the class room and I'm very puzzled in what it has been recommended by studies and experts regarding the setting of the GF. So far I understood you want to stay away from your M-value because it is your supersaturation limit or where bubbles can...

First I want to clarify that I have no afiliation to the entities I mention in this post and I'm posting this as a personal informative message. As I seek to be a better diver and team member, I enrolled my self in the Tek Camp 2018 in the UK for 4 days of what I hope will be great training by...

I need help with a question on the Dive Rite tec butt plate. What is the spacing ( distance ) between the plate holes ( the ones that connect to the harness ) ? Do the D-rings on the plate hold good the weight of Steel 10L tanks ? I'm looking in to this butt plate to attach it to my custom...

In the case of diving with 6 or more tanks, I see everybody mounting their deco tanks in the front. But is this really practical ? If you are deep do you not want complete visual and fast direct access to your bottom tanks, meaning that they shall be as reachable as possible in case of free...

This post is to see if we as a community can reach out and passed on, it is very sad that my grand children if I have the bless to having them and get to meet them will not see coral but in pictures and not in person at the rate we go now. My Dad was born in Curacao and live there until around...

I'm looking for a buttplate as I'm going for a pair of steel tanks in order to complete a set of 4 tanks for bottom gas, the X-deep butt plate don't work as the holes for attaching it to the harness are too much to the center, I want to directly attached with bolts and not double enders What...

I like to share my experience to see if this event need some attention or not. The Dive: 6*C water no deeper than 13m. for 45min Last weekend I went diving, I was coming out from a flu, but days before that weekend, I was able to breath normally through my nose and clear my ears without...

Most of tec divers I have seen use one AL-80 with 80%-100% O2 for the last stop, based in that 50% of those 11L tank is for the Diver and the other 50% for your buddy or in case of an accidental (SHTV) over run of the plan. Then I see the thread over buddy breathing, which we all were taught...

SP G2 uses Buhlmann algorithm, it has a combination of MB and PDIS in this case you can choose to activate it or not. From Wikipidia: PDISs are intermediate stops at a depth above the depth at which the leading compartment for the decompression calculation switches from ongassing to...

Is it normal that a APEX ATX-50 pass a little water when one is vertically inverted in the water ?( head down, feet up ) 2nd stages were tuned in April and seats changed, but it happen before this and after it as well.

After reading the post from Sir. Akimbo about those dives down to 300m, I got curious of which regulators had been used to achieve those extreme depths. I can see that the 332m record from Gabor in Egypt was done with Apeks regulators, what other brands were used in previous records ? Which...

How many of you use angle adapters on your 2nd stage ?, I'm looking for a 110* adapter, I heard to stay away from the swivel adapters, I guess the fixed angle ones don't fall under this category Any brand that I need to stay away from ?

Like in many SB posts the OP starts with one questions and the thread ends talking about what oil you use for you car motor. But then some more questions come out of these derails of conversations and opinions, and this one ended in cold tolerance and DCS DCS and diving cold, but where does...

There are different criterias of the ascent rate after completing your Deco time at 6m. But what could really go wrong after completing your mandatory time + that preventive little? of course I'm not saying fly out of the water after Deco, but what will be the real side effects of faster...

As we observe all current Deco algorithms/profiles and so called strategies, the focus is on long times @ 6m, but since there is NO On-gassing from 12m and up and only Off-gassing is present, why is it that these Algorithms are not re-distributing the time @6m between 12m, 9m and 6m, not...

I bought this from DGX to replace two of my vertical D-rings so I can stream line a little better my tanks and have the other two D rings left that the most to the back to clip accessories or others. Extra Large S/S Rigid D-Ring These rings are actually bolted rings, I want to use Lok-tite on...

How fit are you for a Rescue ? Even that the video was done with divers in Tec gear, it is a valid question to the Rec divers. We know that we shall dive XXX amount of meters/feet in XX amount of time, all good, you can complete this but how are you after this test, are you near becoming the...

It is a very interesting video that shows that if pushed to hard you can become the second victim if you are not in shape.
