XS HP80 vs Faber HP80

[Hatul]

I'm looking to get an HP80 for shore diving and would like advice on choosing the XS Worthington vs the Faber.

I'd like low total weight when walking to and from the beach.

If you want low weight, get an old school (longer length, 2250psi) LP72. The HP80s, IMO, are awfully short. Makes trimming out harder and they are so short you risk pinching the BCD bladder when you sit down. Should save you a bunch of money, too.

That faber Jax referred to is not the one that's usually meant by "HP". That's a 3AA tank, extremely negative. There's no comparing that with the faber FX line of special permit (3442PSI) tanks.

I agree you might look for a LP72. They're really fun to dive with, and if you can get even a slight overfill, hold as much as an AL80. Plus, you can find one for under $100 easily. The short HP80 is sometimes referred to as a bowling ball with a valve.

Yes, as Halocline noticed I actually meant the Faber FX 80 tank, which would be in the same class as the XS HP80. I will look over the specs for the LP72, but my motivation is to get the total weight (lead + tank) down on land, over the XS HP100 I currently dive.

One thing to remember is that the XS HP100 is only a whole 1 lb heavier than a standard AL 80.

If you can get the HPs filled, are you sure you want to give up that extra gas?

 

[Rainer]

An LP72 (or HP80) is a lot lighter than an AL80/HP100. Sometimes, you just don't need that much gas. We have some local shore sites where you average about 20'. We were getting TWO 60 minute dives there on a single HP100. For one-off dives, the 72s made more sense. For those willing to own *lots* of cylinders, having the perfect one for the site in question can be a nice luxury.

They prob want the Faber FX-80 instead of the Faber HP-80 (as noted by halocline above). It's lighter. by about 4 pounds.

I'm not even sure if Faber makes the older 3180+10% HP-80 anymore.

I agree. the Faber 3180's are Extremely negative and weigh much more to carry around also.

From the limited research I gather the LP72 steel tanks are not made anymore. Which would mean the used tank market, which is another problem.

I keep seeing different numbers for the empty weight of the XS HP80 tank, but when you take into account the slightly more buoyant Faber tank, the total weight, tank+lead, for both is about the same. The XS would need just over 1lb less of lead, which is not significant. The Faber is an inch longer. Is there any reason to choose one over the other?

To archieve that, you need to compared weight of the tank + empty buoyancy number.

X7-80, 28 + (-3) = 25lb
HP-80, 32.5 + (-7.22) = 25.28lb
FX-80, 28.6 + (-1.74) = 26.86lb
X7-100, 33 + (-2.5) = 30.5lb
Cat S80, 31.6 + (+4) = 35.6lb

I cant find any number for LP72. Looks like X7-80 and faber HP-80 is about the same. FX-80 is 1 lb heavier. AL80 is almost 10lb heavier than X7-80.
