Im debating between the HP 100, 119 and 130. I know they all are shorter than an AL 80, and the larger 2 have a 8in diameter, which is fine, but i still cant decide.

With the 130s it might be possible to do 2 dives off of one tank, which would be a plus, but do i really need that much air if im doing a single dive off the tank?

Since the weight doesn't bother me, and there is barely any difference in price, should i just go with the 130s and have some extra air for the times im diving with people who have gills, or just in general in case something comes up underwater?

Am i overlooking anything with the smaller tanks?
Thanks for helping me out guys

I don't want to be mean, but seriously, there is an active thread in this section that is currently talking about this exact topic.

http://forum.scubatoys.com/tanks/15951-tank-size.html

General consensus is HP120 if you are big dude and don't mind carrying a heavy tank. HP100 for normal single tank dives, or if you eventually want to dive doubles. You can just but another HP100 and put a doubles manifold on them.

I saw that thread, but nobody had mentioned the 119s or 130s, and it seems like a more general al/steel low/high pressure tank decision.

HP100s if you're average build and shore diving =)

I chose steel 120's.
+They fit in the same tank brackets as AL80 (7.25")
+They carry my backup gas inside. (No redundant regs but I am OK with that. I carry a pony on deep dives).
+I don't have to mess with my BC straps if I choose to dive an AL80 (7.25" thing again)
+Weight distribution works for me (5' 11")

-They are heavier than AL80 when full and out of the water.
-The fills may cost you more than a smaller cylinder.
-They are too tall for some divers

I plan on getting a couple of Steel 100’s next. I will buy them doubled and then convert the valves to singles (remove isolator and plug opening). This way I will have all the necessary parts to double them back up when the need arises. At least that is my plan J

I'm new to all this and have a very old 72 which may not pass its next visual. I'm 6'-3", 235#, and do shore and boat diving. Money is not a problem. Until I improve my skills, I'm sucking air like a cheap *****. Should I assume an HP 130 for singles and a matched pair of HP 100's for later doubles? Any help would be appreciated. I also hope this ain't a thread hijack thing, like I said I'm new to all this.

I can't see a 17 year old needing more than a 100 for adequate gas. They are very light and compact. The 119's and 130's are very heavy.
My 17 year old buddy dives 65's.

Well here is my 2psi.

Available Tanks:

HP100 7.25 dia 24" long 33 lbs
HP120 7.25 dia 28" long 38 lbs
HP119 8.00 dia 24" long 42 lbs
HP130 8.00 dia 25" long 43 lbs

At your height there is no advantage to a short 119 over a longer 120, and there is a 4 lb weight penalty. I don't think the extra 8% of air you get in a 130 justifies the 5 lb weight penalty to carry it around (as well as the 8" diameter), so the 120 is the best choice IMO.

If money is not an issue and you are sure you are going to go to doubles, you could get two matched 120's and an isolation manifold right now. Remove the center piece and plug the ports on the tank valves, and you have two single tanks to use now and avoid trips to the fill station. Later, you can band them together, and you have doubles with no extra expense. The double 120's are only 10 lbs more than the double 100's. This should not be an issue at 6-3, 235#.

That said, it is all personal preference. I dive an HP100 and am thinking about a HP119. I am 5'10" and the shorter tank gives me better horizontal trim, and I have no plans on ever diving doubles. A HP119 and a pony bottle will get me anywhere I plan on going.

I LOVE the Worthington HP130's. I have doubled up Worthington HP120's which are nice too, but I like the fact that the 130's are shorter. Someday I will buy two more HP 130's to double up. With my air hog buddy I easily get 2 dives off of it. For a buddy with similiar SAC and they are diving 80's or 100's I just have a good reserve left. I do not think you can have to much air. Some people do not like to waist the air that they have paid for, since most shops you pay for a fill weather the tank is empty or only half full. I have a unlimited air fill card so I do not mind taking the tank in with 1000psi. They really are not that heavy out of the water. I have done plenty of shore diving with mine. I guess if you are near an ocean and doing a lot of charters then the 8" diameter might be a factor if the boat is only set up for 7.25" tanks. For the money I would spend the extra and get the 130, but that is just me...

My newly certed 14 year old buddy, who is on the JV soccer team, ran through 2500 psi in a AL50 in the same time I used 2100 lbs in an HP100.

So you can see why I need to get a HP119 when he uses an AL80.

Yup. I used to use pumped up LP 98's that gave me about 120 CF. The 17 year old in his 65 would run around the bottom like my dog after a bath. I was still the one to thumb the dive. :)

Well when I was a teenager I could make a 72 last.

im 5'7"
and all the diving i do is boat or from shore at lake mead, so we set up literally at the water, and we drive right up too, so no walking 3 blocks like in cali.

the 120s are way too tall, so i would rather deal with the 119. and the weight isnt a big deal as i dive dry pretty much year round, and i get free fills, so im just wondering if there would be an advantage to a 100 or 119 over a 130 other then weight and size. would they trim out better or is the difference minimal?

i just wanted to make sure im not overlooking anything and that i have all the bases covered before i make the investment of 2 steel tanks.

I think the shorter steel tanks trim out better, at least for me. My feet tend to sink, even when I have my knees bent so that my calves are vertical. So anything I can do to get the center of gravity to move closer to my head is a plus. Even in a HP100 worn up as high up as practical, I need a couple of lbs of weight on the upper tank strap to trim out.

For me personally I did not feel much difference between the 130 and 120 (when they were singles). I have not dove 100's or 119's so I cannot comment specifically on them versus the 130 but I would guess that there would not be much of a difference. I am just saying this from MY point of view, I would buy the 130. But that is just me, Everyone has their own reasons why they like what the like and buy what they buy. Good luck on your quest...

I'm only 5'6" and I could not be happier with my X8-130's (XS/Worthingon 130). The weight penalty is easily offset by the weight I can remove from my harness and the air lasts for days (well, a lot longer at least).

As far as the extra 3/4" girth... Hardly noticeable!

I'm 6' 6" and I've dove with a LP112, LP108 and HP130. The LP112, after several dives, I was able to get almost perfectly trimmed. The LP108, after two or three dives, I was somewhat trimmed but still feet heavy. The HP130, after two or three dives had me in almost perfect trim.

So which should I chose? I'm going to go with the HP130. It seemed easier to trim out with. I'm sure I could adjust here and there but, most of my LDS's won't over fill LP tanks so, I can actually get more out of the HP130 tanks.

Food for thought, YMMV.

I went with the Worthington 130 and picked it up at AWBA yesterday. I also traded in my old BC for a bp/w so I took the whole thing out in the pool last night for a test run. It sunk me with no additional weight. I still have to dial in the trim. I wanted to run it out and do a surface weight check at 500psi and I'll have to admit that that sucker holds a LOT of air. Took longer than I thought it would to empty it. Did give me plenty of time to play with the new gear. I'm glad I went with the 130. Came with the convertible Pro Valve too so that's nice.

Missed you by that much!! A few of us from http://www.msscuba.com and the other "scuba board" met up for a weekend of diving at ABWA. I dove my dive buddies HP130 and that's what I'm getting soon.

I have a couple of HP130s and a HP100. When hiking cliffs to get to the water, I only use HP100s. The HP130s are great as long as your buddy also has one when boat diving or easy shore access.

Any tank that holds a minimum of 100cuft is perfect for me. :)
