Question Mod3 motivation (wreck or cave)

[DiveLikeAMuppet]

I’m contemplating whether to aim for mod3 (100m ticket) in about 2 years, looking for a bit of inspiration.

What would be your absolutely must see wreck or cave in the 70-100 meter range that is worth the added effort and risk as a target?

I had Malin Head classics (60-70m) as my CCR/mod2+ goal and loads of other wrecks on the South coast of UK, totally worth it and some of the best diving ever.

I feel that mod3 depths call for team bailout and a lot more more contingencies compared to mod2+, you can’t stay self-sufficient. Not talking about diving a reef in Egypt just to see “100m” on a dive computer but proper wrecks, North Sea.

What inspired you and was it worth it?

I am fairly new in the realm of technical diving in general and also the mod1 world so, add extra grains of salt

What would be your absolutely must see wreck or cave in the 70-100 meter range that is worth the added effort and risk as a target?

My only personal motivation as a wreck for such depths (70-100m) is the HMS Britannic in Greece, it’s the sister ship of the Titanic and sits at 90-120m slope so that’s easier than chucking out 250k for a seat on a death-can to come close to the likeness of the Titanic

It’s not really enough to push me for mod3, I would say other things are (bluehole bottom, caves maybe.. ), and I’m far from that anyways for now

I’m not that big of a wreck person anyway (I actually like shallow wrecks a lot as they have a „fun“ factor in „rollercoaster“ like manuvers due to the peculiar way they have landed onto the bottom (like ghanis D)

Probably US wrecks are way cooler to visit as they tend to be more „controlled“/planned, so they seem to have more potential for actually penetrating and exploring in a way like the Grove (just saw some videos of it)

I’m more interested in caves (from an overhead environment) pov; so something like Tiger caves below the Canyon at Dehab at 75-110m) among other things are probably as deep as I _realistically_ want/hope to go; of course I’m fascinated by 320m double rb/dpv cave dives, and sometimes daydream of them — but I’m not sure I’m cut out for it (doesn’t hurt to train to be the best a diver I can be regardless)

Probably I’ll never really need mod3, let’s see how things develop first with simpler skill sets like intro to cave

Edit: probably everything that I saw a video of that called out for me is actually at shallower depth anyway — so it feels a bit moot for me to think about it much this early on in my „experience“ career, but I also wanna know about what dives others recommend

Team bailout... When deciding to use team bailout, or not, you have to consider the environment and whether it's appropriate in the location. In my mind, team bailout is really only applicable in places where there's almost no risk of buddy separation and the environment is appropriate for bottle swapping.

Looking at a few environments...

Deep diving in high current / bad weather environments / poor visibility - team bailout may not work where the risk of buddy separation is high. Example, in SoFla team bailout is a fools errand due to the prevailing and unpredictable currents - the question is "when" not "if" a team gets split due to the current. Team bailout does you no good if you can't find the team. In these environments where you're carrying all of the gases the entire time, shorter bottom times (requiring less deco gases) and perhaps the use of DPVs would be in order.

Deep cave diving / mine - In environments where you can drop off (stage) gases, team bailout may be applicable for decompression gases, but every diver should have enough bottom gas to get to deco (or at least to safety bottles that will help them get to deco). If you're separated from the team and don't need the staged gases, leave them there in case your teammate is in need.

In terms of what would be involved in team bailout, every diver should have enough open circuit deep gas to get them to the first deco gas, but then the deco gases could be staggered. Let's say you and I are doing a 100m dive in an area with no current and decent visibility and we're planning a dive that 4 deco gases might make sense, we would both have an appropriate amount of deep bailout (something akin to 12/65) and then we could stagger the deco bottles. Ex. I could take a 60m bottle and 21m bottle, you could take a 36m and 6m bottle.

Not in my experience so far. I am only doing mod3 dives where I am self sufficient for bailout and team is there as additional safety net.

That’s what I meant as team bailout - situations and depths where it’s not practical for one diver to carry all the deco gas. And all that comes with that such as team separation risks.

Loads of uk wrecks in that depth range, (70-130m)
And as much as on a uk dive boat you would have support from others in the water I always try and carry enough off board gas, but 4 Ali 80,s does start getting busy, a bit of a juggling act, (team bail with a reliable buddy that your well dived with is the way to go but I don’t like entering the water without all my own bail gas personally)
The 100m+ stuff is a bit of a considered risk, as you probably have already played with run times and mixes on a computer I’m guessing that’s an underlying part of your question regarding deep uk stuff,
If you have problems and your on your own I’m afraid this is where level of training, practice and experience come in, (serious consideration has to made in to the bailout ccr if your doing a bit of time at the bottom with serious depth, but that’s a whole other question and the answer is very dynamic)

As Billy Deans used to say
“If you walk the frontier one day you will meet the Indians”
And it’s always stayed in my mind. Be sensible, well trained, well prepared and practise, be confident in your training and abilities at any one time but always be prepared to deal with issues.

The wrecks in the deeper end are rewarding though.

That’s what I’m looking for - a bit of inspiration, to have a couple targets in my mind. Anything specific that made you think - all the work was absolutely worth it, even after 2 hours of deco?

And as much as on a uk dive boat … would have support from others in the water I always try and carry enough off board gas, but 4 Ali 80,s

Have you considered two overfilled steel 12s and a prayer, like some of the British legends who dive 80-100m? (That was a joke but I’ve seen people carry far too little bailout …)

The 100m+ stuff is a bit of a considered risk, as you probably have already played with run times and mixes on a computer I’m guessing that’s an underlying part of your question regarding deep uk stuff,

Yes, that’s the question - risk/reward of the diving itself but also the cost and effort to get to the level and stay at the skill and comfort level.

Deep caves. New skills and perspectives.

Set your sights on a malin deep week,
HMS Viknor
RMS Amazon (my favourite wreck)
Flavia
Transylvania (weather didn’t allow)

Off the bottom of Ireland amongst others there are Lusitania (very broken up now) and Miniehaha which was amazing.
Some folks do huge deco, obviously you work up to it so it’s not suddenly a big chunk of time I’d say 2,1/2-4hrs isn’t unusual and you can pass the time with a bit of horseplay with your mates

I’ll be honest, due to time and other commitments I’ve just been diving away at the south coast of England this last year, Dover or Eastbourne plenty of good stuff about, loads of 50-65m stuff.

Ps, some of the old hair raising head bangers that used to do deep air with glowing cylinders still frequent the boats I find myself on, sometimes the pre / post dive conversations are as memorable as the diving

Attached is a picture of a book I’d highly recommend.

My motivation for doing MOD3 was deep reef exploration and documentation, there is much to be discovered particularly if you have an eye for marine life and work with a local marine research institute.

We utilise a shotline with tethered drifting deco station where we stage shallow bailout gas and utilise team bailout for deep to intermediate bailout. Risk of team member separation is low, vis is good, currents are variable we and use DPVs.

Anyone who claims they are self sufficient diving these sorts of depths is fooling themselves. Suffer a CO2 issue you will be needing your team to get you back to the surface, and most likely needing their deep bailout as you breath like freight train.
