Good afternoon, After some introspection, I need to dive more, post less, and not be a slave to the new posts button. please delete my account, profile, and personal details. post contents do not need to be wiped. kind regards and safe diving to all, --Alex

RMV, SAC, SCR (Surface Consumption Rate) and SGC (Surface Gas Consumption) have been used interchangeably in the NAUI and SSI A/OW classes ive been involved with as resting air consumption rate at the surface. sometimes there's a SAC -> PSI, and RMV -> CFM differentiation, but it doesn't seem...

AFAIK, no. PSI as a reported unit is not very useful on it's own, as it depends on both cylinder size, and depth. SAC in CFM/LPM is independent of either, and can be used to figure out PSI/min relatively easy using tank factors as rhwestfall mentioned. my SAC typically sits around .40~.45cfm...

Forcast now shows sunny, so yay for that. We're hanging out with the Neptune's rejects crew in pavilion 13 and 16 with the pop-up awning. Have camp set up at the very top with the black Chevy truck and the grey Chevy van. Swing by and say hey if you want.

hey John, i don't think anyone here is questioning the requirement, as basic reasoning explains the 'why'. the continued discussion is the ambiguity in the otherwise precisely stated published standards. ambiguity which has caused more then a few people confusion. this is why i posited that a...

Hey John! as mentioned by other posters in this thread before me, this is something that makes sense, but it is not described as such in the standards, policies and procedures as of v8.0: no mention of the primary being corded, or configured for an extended burn time. a minor revision to...

welcome to scuba and the board! myself and the wife are planning to head up to gilboa quarry the weekend of September 9th for a skills and drills weekend, y'all are more than welcome to join us. im sure someone will chime in with a quarry owner comment, but we've not had problems with him in 4...

wife and i are heading down to pennyroyal quarry the friday before, and van camping/diving the weekend and through the eclipse. downside is forcasts are calling for rain currently. :( 2017 Solar Eclipse Dive - PSC Blue Springs Inc.

strangely enough, and much to my surprise, the jet fins Just Work with our dry suits, 5mm wet suits, and lavacore skins. the 5mm wet boots we're using are quite floaty, which likely offset the negativeness of the jets a bit. of course, YMMV.

Mike seems to be pretty scarce lately. He's also had two of his cats get killed this year, which sucks for anyone who's been a regular up there. :-( Follow the rules, and you'll have a good time. Break the rules or be stupid, and yeah, you're going to get called out on it. Personally I've...

wife and i also use a 7' with a single tank rig. have ran through the 'streamlined OW' rig with a 40", as well as a 5', but like the 7' best by far. personally like the canister analogs considerably more than stuffing the loop into the waist strap. if its not in your mouth, its clipped off...

using seconds as the basis of time seems more reasonable, makes it a whole lot easier to not re-tool all the software. dont even have to change time_t around or restart the epoch! 16 2/3 minutes per kilosecond, 3.6 kiloseconds per hour, 86.4 kiloseconds per day, 604.8 kiloseconds per week...

its not, and its not. GUE min deco and min gas planning do not include safety stops; min deco clears any incurred ceilings via slowing the ascent rate at half max depth, and min gas is planned on that slow ascent rate through the entire ascent. following those rules, ascent would have been...

its been crashy in my experience since version 5 across a large variety of hardware, both quadro and firegl boards. i just have that effect on electronics, if they can break, they will break when i use them. about the only common thread is that its usually been on dual socket boards with...

this seems a bit odd, and i cant really picture it in my head while making sense. with both my and the wife's BP/Ws, which are both steel, one being a freedom contour with a hollis s25 wing, the other being an OMS with STA mounted in the lowest set of holes and DGX 25lb wing, when diving...

Hey Devin! welcome to the club! there's a pretty regular group of people out of Columbus scuba, not to mention the great lakes wrecking crew, that frequent Gilboa and other local quarries. hopefully we'll cross paths sometime and can get a dive in.

you nailed it right on the head, Kevin. as much as i dislike the term 'safe space', its what a constructive learning environment needs to be. those videos are critiqued very hard, with every single little flaw is pointed out, sometimes with pretty brutal and blunt feedback. it is an extremely...

during our fundies class, every drill was recorded, and we were debriefed while reviewing the video afterwards. it was extremely strongly explained that no copies of the video were allowed outside of the classroom environment, and are completely destroyed once the student evaluation by the...

personally, if an instructor pulled that stunt in a class that i paid a large cargo ship load of money for, my gear would have immediately been chucked into the back of the car, a refund for any remaining class days demanded, goodbyes said to classmates, and the long drive home started. even...
