Making my way into Technical Diving

[EgyptinMagicin21]

Hey everyone,

So I'm thinking (less thinking, and more moving towards) about getting into technical diving. A good friend of mine, just took a Fundamentals class, and I fell in love with the kind of training and mindset that technical diving requires. I love diving, and I feel that this is the next step in my dive training.

I have been looking around at gear, and the forums for any information in making my decisions for my gear selection, and I figured it would only do me good to post what I was thinking about getting, as well as my reasons for those particular selections.

Before I start listing, I understand that technical diving...well to be honest, has a stigma for either attracting a-holes, or turning divers into a-holes. So I only say this because if for any reason, one of my selections isn't the best, or could be improved, please explain why, and not just bash me for picking that selection. I'm here to learn as much as I can, not be ridiculed.

Tanks:

I'm leaning towards LP Steel 85's. I was initially considering HP Steel 100's, but with their weight, they might possibly be the only thing I use as weight, which would prevent me from balancing my whole rig, and be dangerous for situations in which I needed to drop weight. I plan on purchasing these at my LDS, if they can get me a good enough deal. I found a whole set up, (tanks, bands, and manifold) for under $800, online.

Regulators:

Scubapro MK25/S600, for both my primary, and back up. This would be DIN connection of course. I don't have much reason as to why, but from experience, and talking with my friend, these seem to be the best for the price I would be willing to pay.

BC:

I plan on buying a whole Halcyon rig. I will be getting two wings, one for single tank, and one for doubles, and then a backplate, as well as the storage pack, as well as all the little snap-clips...etc. I'm concerned as to which backplate to purchase. I don't have the money to buy two separate set-ups, but I don't want to overweight myself with the SS tank. I want the SS for my STA, but I think Aluminum would be the best for doubles.

Gauge:

I think a simple pressure gauge will suffice.

Exposure suit:

I already have drysuit, so no cost there.

Light:

I'm going to put off the canister light for a while, just because I'm only looking at spending about $3000, and I go quite a bit over, even with a relatively cheap canister light factored in. Pending on how much of a deal I can workout, I may be able to swing one. Any suggestions would be great.

Accessories:

Safety sausage, and all the clips and string for attachment. Thats all I can think of for now.


I guess thats all I can think of for now. If I forgot anything, please feel free to add in, and explain why that would be needed, and if there are any changes, once again, please explain why, so that I may see it as a better way of gear configuration, and not just another diver giving me the "my way, or the highway" treatment.

Thanks again for all your time, and I hope to learn a lot from this.

so which are you? An a-hole to start with or are you planning on becoming an a-hole now that you are thinking tech? Really bad way to make friends

Dont know what advice you are really looking for. You got the gear figured out. Just get in the water and start working on your frog kick. Google back kick and helicopter kicks and start trying those out. Get your buddy to teach you the basic 5 and s-drill, do those drills on dives with him. Start being aware of your trim, buoyancy and gas consumption. Take a fundies class when you feel ready.

 

[DevonDiver]

There's no reason to be an a-hole within the tech sphere. Just keep an open-mind, listen to everyone's opinions, pick the ones you agree with, never stop seeking to perfect.... and then forgo the opportunity to regurgitate those opinions as if they were gospel.

The fundies course is a great starting point, as it serves to benchmark the core skills that should be perfected 'pre-tech'. If you do some searching on Youtube, you will find some informative videos on the fundies skills.

Your equipment configuration plan seems sound. You can't go far wrong with a Halcyon rig and Mk25/S600 regs. The question of tank size/weight/material and backplate material will be determined by your weighting requirements. Be wary of getting your set-up too negative, as the Halcyon wings are only single bladder....so unless you are diving drysuit, you need to consider the impact...and how you would cope with a loss of buoyancy from your wing.

I understand that technical diving...well to be honest, has a stigma for either attracting a-holes, or turning divers into a-holes.

A fair proportion of the world's population is comprised of a-holes, so one should not be surprised to find that the incidence and prevalence of being an a-hole in tech diving is reflective of that in the overall population as a whole.

 

[DA Aquamaster]

To be fair, tehcnical diving does seem to attract a boit more than its fair share of A-holes who get into the sport for ego driven reasons. But what really makes it worse is that msall percentage of divers and their attitude reflect badly on the 90% if divers who are not that way.

Andy is on the mney when he identifies divers who hear an opinion and then reguritate it as gosphel as being one of the primary A-hole/technical diving association problems.

You talk about being attracted to the mindset. If you view that as a rigid adherance to doctrine or protocol, you are gonna be an A-hole. If you view it as a mindet of always seeking to increase your understanding, always thinking and always knowing why you do things the way you do it, you won't be an A-hole.

With regard to regs, I switched from the Mk 25 to the Mk 17 shortly after the Mk 17 came out 4 or 5 years ago. The Mk 17 is in my opinion a better first stage overall with better hose routing. The Mk 25 has more flow rate (300 SCFM compared to 177 SCFM) but it is at least 100% overkill and not worth the compromises that are required.

Similarly, the G250V with it's larger diaphragm and all metal air barrel is a much nicer second stage, especially on long dives where dry mouth could otherwise be an issue with the S600.

I agree with going with an AL plate, but I am not a real Halcyon fan. They are, to put it bluntly, over priced. I saw an Al plate last weekend for $180 with a SS plate selling for $200. $180 is way too much for an AL plate and a basic one piece webbing harness does not need to cost nearly what Halcyon charges for one. You'll do just as well with a Dive Rite or OMS AL plate and/or harness and save money doing it.

I have Halcyon single (28 pound Pioneer) and double tank (55 pound Explorer) wings, but I also like Tobin's wings at Deep Sea Supply.

The bouyancy differences between LP 85's and X7-100's are fairly minimal (neutral versus -2 lbs) and weight weise the X7100's are only 2 pounds heavier. Unless you can get 3600 psi cave fills in the LP 85's you'll probably find yourself wanting more gas.

If you are really concerned about the potential to be over weighted (which is frankly not an issue in a dry suit where you are also diving dry - offering a source of redundant buoyancy in the event of a wing failure) save your self some money and just dive double AL 80's. You give up very little capacity compared to LP 85's and they will cost you less.

AL 80's are not a bad choice for starter doubles as they are light weight, very inexpensive, have enough gas to be useful on dives to 150 ft or so and can be recycled as stage bottles once you move up to larger steel tanks. Whe you do so the 7" bands can be used on any 7" diameter tank - like HP 100's - and the manifold (as long as you avoid face seat manifolds) can be used on any set of 6.9-8.0" diameter tanks.

Generally, the most common steel tank doubles choices are HP 100's (X7-100s, E7-100s or FX-100s), LP 95's (Fabers are lighter and greatly perferred over Worthington or PST), HP130s (X8-130s or E8-130s), or LP 108s.

If divers move away for those choices, it is normally because they have a very specific reason or need and/or are really tall and prefer a longer tank like the X7-120. Otherwise the other available tank options all have one or more traits that makes them less than optimum compared to the 4 basic tanks listed above.

Currently, you can get a Dive Rite 10 W HID for around $350-$400, so if you save money by moving away from some of the gear with big blue H's on it, you can add a can light and still stay under budget.

I don't know about tec divers being A-holes, but there are certainly plenty of 'em who are very loud and prefer to shout rather than listen. You will also see a tendency towards being patronising to non-tec divers and newcomers.

But they are not all like that. Don't assume the loud ones are representative.

First thing I ever read about tec diving was Gary Gentile's book The Technical Diving Handbook (which should be recommended reading for all divers, tec or not). Pretty much the first thing he says is that any gear configuration will involve compromises, so you will need to work out what is best for you and the type of diving you will do over time. That view is an anethema to the DIR philosophy, but I tend to agree with the sentiment.

 

[rustyshakelford]

check out edd at caveadventurers.com. I think the blue H is over priced and i personally dive dive rite for my bp's (AL and SS) Harness's (Hog and transpac) regs (RG3000's and SPG's) and can light (DR700) and wings (Classic 360 and rec-wing

i think their cost is a little more reasonable and edd can make you a steal of a deal and his customer service is second to none.

good luck

I agree with most of what DA Aquamaster said.

85s are nice and compact, but you can always find a way to trim out bigger tanks and you will likely find yourself wanting more gas.

I'm in the same boat myself right now with 100s. I want more gas, and am looking at a larger set of LP steel tanks (like 120s) which are massive (I'll keep a set of 100s for shore diving, the 120s/whatever I get will be boat tanks exclusively), but get the job done.

I haven't used the Mk17s, but the 25s do offer clean hose routing.

So I'm thinking (less thinking, and more moving towards) about getting into technical diving. A good friend of mine, just took a Fundamentals class, and I fell in love with the kind of training and mindset that technical diving requires. I love diving, and I feel that this is the next step in my dive training.

A very reasonable thought process. I originally expanded in that direction because of a desire to improve the precision of my diving, to develop additional skills, and expand my depth and dive time options. It does not make one a better human being, a more 'worthy' person, etc. If anything it is a humbling experience, well worth the time, money and effort.

DA makes some great comments, and several of mine will echo / build on his.

You talk about being attracted to the mindset. ... If you view it as a mindet of always seeking to increase your understanding, always thinking and always knowing why you do things the way you do it, you won't be an A-hole.

And, you will be in the 90% that DA refers to.

Tanks: I'm leaning towards LP Steel 85's. ... I plan on purchasing these at my LDS, if they can get me a good enough deal. I found a whole set up, (tanks, bands, and manifold) for under $800, online.

Nothing wrong with the tanks. Outside of FL, where cave fills are more readily available, I infrequently see LP85s in use, at least in the mid-Atlantic areas. HP 100s, 119s, and 130s, as well as larger LPs are a bit more visible. I agree with DA about double AL80s as a possible 'starter' set. Less expensive, great trim, equivalent gas (160vs 170) when filled to working pressure.

BC: I plan on buying a whole Halcyon rig. I will be getting two wings, one for single tank, and one for doubles, and then a backplate, as well as the storage pack, as well as all the little snap-clips...etc. I'm concerned as to which backplate to purchase. I don't have the money to buy two separate set-ups, but I don't want to overweight myself with the SS tank. I want the SS for my STA, but I think Aluminum would be the best for doubles.

My only hesitation about the rig is the price-value proposition for Halcyon. There may be more cost-wise approaches, including used BPs, and simple web rigging. Good decision on separate wings. The only time I find an AL plate useful is 3mm wetsuit diving with double steel 120s. I use a SS plate for all singles, and all drysuit doubles. But, that is just my experience.

Light: I'm going to put off the canister light for a while, just because I'm only looking at spending about $3000, and I go quite a bit over, even with a relatively cheap canister light factored in. Pending on how much of a deal I can workout, I may be able to swing one. Any suggestions would be great.

Currently, you can get a Dive Rite 10 W HID for around $350-$400, so if you save money by moving away from some of the gear with big blue H's on it, you can add a can light and still stay under budget.

And, this is a very nice little light, well worth the investment. I would put a can light ahead of some of the other items (Halcyon storage pack, for example). I bought a drysuit very early (a year after I started diving) and never regretted it. But, I waited far too long (6 years) to buy a can light, and wish I had purchased one the first year I was diving.

One thing I'd recommend is trying to find a local 'mentor'. Amongst others, I believe SoCal Tec Divers is close to you. I know they dive a lot down here in caves as well a lot of techncal wreck diving and have some very experienced technical divers.

As for your choices, I'd wait until you've taken some of your tech classes before I set that in stone. You will certainly find that some of your reasoning will change.

Tanks: Tech divers usually do not add additional weight and want the tank + backplate to be sufficent to sink them. For your area, I'd suggest HP tanks as you probably can't get overfills in SoCal.

Regs: There is a tendancy to steer away from S600 and go with the G250 series in tech circles.

Backplate: Go with the SS one if your going to be doing ocean diving.

Those are some questions you might want to ask, but again, I'd suggest finding a local mentor and waiting to purchase most of your gear until you actually get going in some of your classes.

Just my 2 cents.

Be safe and have fun in the water! Bruce
