Honestly for me lp85s with 32 feel like bricks to me when combined with the already heavy-ish Meg. I've done that in FL a bunch of times though. They are comfy with mix in them. I suspect you'll like them once you move to mix in them. Even 130s are nice with 18/45

If every dive is "problem-free" you're blind and not reflecting *critically* on each and every dive with the aim of continuous improvement in skills and attitude.

There is no Teflon in any scuba reg seat that's for sure. Teflon is also a completely impossible as a scuba valve seat as well - it's far too soft and will extrude around the sealing cone under pressure. They look and act like nylon because they are nylon seats. Well the gas hitting the valve...

In a cave? or in open water? LP85s up through hp130s actually ride pretty nice with 35-70% helium in them but the tails are going to ride up. Diving two of them SM in a cave with a backmounted CCR is legit. In open water I carry an AL80 and then start adding deeper and deeper deco gases to...

Yeah the seals actually last about as long as the prop blades - the plastic in those gets brittle over time. likewise the clutch. There are quite a few parts in the tail aft of the shaft seal which are comparatively weak. The Cuda is about average in terms of prop and shroud resiliency

The double has 2 stages of the same size alternating in parallel action. The two stage has 2 stages of different size acting in series https://www.haskel.com/en-es/products/gas-boosters/pneumatic-driven-gas-boosters The AGT series from haskel will pump from <10 bar up to >300 bar. But it's not...

This is why zero-to-hero full cave programs are such a bad idea. The mechanical skills can be trained in ~10 days. The mental rewiring of the brain comes with experience and pretty much everyone needs that time underwater, under rock, for dozens+ of dives to cultivate calm under stress.

The genesis warpcore has even more user-friendly batteries. It's not a question of power, even in the Cuda the shaft seal leaks and needs periodic service and the trigger rod will corrode into the strut or sometimes lose its magnetism and the switch basically fails. These are two Cuda flaws...

The Cuda is reliable and a solid performer, although the trigger rod and the shaft seal are both pains and relatively big weak spots. Would not trade for a blacktip

I see Faber 85s and 95s up there fairly often. And 72s even - but no pluses, and not even TC ratings on those. They are getting Canadian hydros somehow, although it's beyond my understanding of TC regs how that works. For the record, it's basically impossible to get a plus on a lp72, any of...

I've heard many a dive shop story of "and then my battery failed" or "I didn't have both deco gasses programmed" and lordy you'd think it was a total disaster. Vs knowing that a 190ft wreck dive has roughly 5 mins less deco time than a 200ft dive of the same BT, OMG the scuba police are coming...

Not exactly. TC doesn't have pluses in their stamped pressures nowadays. Dual rated DOT and TC tanks will have psi and a + as well as a metric service pressure with no plus. They are the same pressure though.

Transport Canada doesn't even have or use the plus whatsoever! That is the US DOT psi rating. The TC rating is in bar! And includes the plus level of pressure with a tiny amount of rounding. The only exception is very old US DOT tanks which predate TC approval and have some sort of reciprocal...

In Caverns Measureless to Man, they're diving 1/2s plus 200, so 1/3rds is actually an improvement over that :D

Not the first time old news has been repackaged with a flashy title :acclaim:

This was a downstream traverse, in a strong siphon, by intro divers, carrying a camera, who had never been in the system before. Being in sidemount certainly didn't help, but really was not directly related to this OOA accident. And *ehemmmm* as I previously pointed out, they all swam around...

Except if you look at the OOG fatalities that have happened in the last two+ decades one diver doesn't just spontaneously go OOA at max penetration with 2/3rds left for the buddy(ies). The whole group swims around lost until they are all low on gas and finally the first diver goes OOA and they...

In your FL centric universe sure... In MX there are next to no 104s at all and the "standard" cave doubles are al80s. A "standard" set of OC bottles in my neighborhood is a set of lp45s

I bring smaller bottles - but as a general rule I am not going any further distance than I would on OC. I am staying at that distance range longer (or it's taking me longer to find the way on in the cave at all).

They turn basically square as they get old. They are in compression but the force on them in the groove is actually lateral. So imagine the gas is trying to extrude them through the tiny slit between the valve and cylinder. The gas smashes them into the square groove so they never come out...
