    Question Is the KISS Sidewinder the best to learn on on & keep for a lifetime?

    It actually appears to be PVC. At least side by side with PVC conduit and the delrin/acetal in the Meg.

    Question Different tanks for SM and CC bailout?

    @PfcAJ took me to Eagle's once a number a years ago now (~2017). It was a fun dive but the deco (4hrs) to exploration (0 hours, 0ft new passage) ratio is all out of wack for me. Also not into travelling to FL anymore for safety & solidarity reasons. It's a nice cave, just not worth it as a...

    Question Is the KISS Sidewinder the best to learn on on & keep for a lifetime?

    Same and I haven't actually had the tower problem... I have other concerns, as a general rule my concerns revolve around: 1) the build quality which is unique to the sidewinder and 2) the obsession with "sidemount" when a sidemount CCR has many compromises compared to a backmount CCR and...

    Provocative talk yesterday at NSS-CDS: Toss out the rule of thirds?

    You don't seem to have any cave training or experience. The very real risk of drowning tends to make people really anxious over the course of a long exit with less and less gas available by the minute.

    Have not been made in decades and the cost on the used market is astronomical.

    Are you sure? That rod looks like bronze to me

    Small problem... it's perpetual vaporware

    Question Is the KISS Sidewinder the best to learn on on & keep for a lifetime?

    Nevermind the orifice itself clogging. I know quite a few folks that have clogged orifices and its so pervasive a problem they just keep diving them as full manual units. Compare with a fathom needle valve which engineers out the whole problem.

    Question Different tanks for SM and CC bailout?

    For big backmount cave, I like the Meg with 2x SM steels. Those kinds of cave dives are kinda rare for me lately. In the ocean/great lakes I dont really dive deeper than 240ft-ish often which is the margins of the fun zone. So it's rare that I add a deco gas deeper than a 70ft bottle. Probably...

    Question Different tanks for SM and CC bailout?

    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.

    Question Valve for 100% O2 Deco Bottle

    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...

    Question Different tanks for SM and CC bailout?

    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...

    DiveExtras - best i've used

    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

    O2 booster working from 10 bar (150 psi) to 300 bar (4'500 psi), does it exist?

    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...

    Provocative talk yesterday at NSS-CDS: Toss out the rule of thirds?

    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

    How long does a steel tank usually retain its + rating in hydro?

    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...
