LP77's

[Teller]

I came across a deal on some LP77's but I don't see many of them around. Just wondering if anyone has this tank and what their opinions about it are? I am considering grabbing two for a set of doubles for my swallower dives, prob use at 165 max depth. Any thoughts.

basically 7" versions of the lp95's, or LP versions of the HP100's. Weigh as much as AL80's on land, so I'd rather have HP100's, but for the right price I'd snag a pair. Not a common tank size though so that's why you don't see them often, which is obvious :-D I don't think they made them until worthington came out with them a few years ago, and probably haven't caught on with the HP100's out.

seems to me like you could get the same amount of gas as a AL80 without having to overfill and have better buoyancy characteristics then AL80. I see people use AL80 for doubles from time to time, to me it makes more since to grab a couple 77's. They are only about $60 more than AL80.

Personally I'd always take LP tanks over HP. Better chance of getting a good fill, if you have a good shop to work with then you can get really "good" fills. Ie if they are 77 cu ft @ 2640 then at 3000 they'd be 87.5 cu ft. Take em to 3200 and you have damn near 95's. 93.33 to be exact. I'd call those very nice doubles.

And if you have your own compressor or shop that will do cave, or as we call em up here wreck, fills to 3500 you have 102's.

I have a pair of them I love mine. Jim is correct as usual, they have the "+" rating and you can have 80 cubic feet in a smaller size tank when they are filled passed 2600 lbs. Also they weigh more than an AL80. So less weight to carry with if you are comparing with an AL80. In salt water with my tank and SS BPW I need no weight. If I needed an extra tank I would grab one if price was right. Here is a link to XS Scuba's Site. Scroll down and look at the weight full and empty. Also has cubic feet listed.

Shops around here will only fill to rated pressure so if I buy 77's then im getting 2640 psi fills. I still think they would make for a good set of doubles for shallow dives.

If you have any HP tanks you can transfill and squeeze a little more air in them after getting a 'by the book' fill. I occasionally do that with my double 72s on the rare occasion I need more gas.

I have 2 of them. I dive them singles and also use them SM. I'm actually fond of mine. I don't have too much trouble getting 3000psi fills and I like the buoyancy swing, they are just barely negative at the end of a dive. YMMV

I just bought my third LP77 tank. The 77's hold plenty of air for my diving needs, they are shorter than an AL80 and I knock 4 pounds off my weight belt.
