For Michigan or Florida, that is a cheap price. I have been bugging my fundies instructor to double her pricing. She’s booked out a year in advance, and burning the candle at both ends. She can’t do that forever. And the simple solution is: charge more. She can make the same amount of money and...

I used to have separate singles and doubles setups. The wings are different, the regs are different, so it made sense to just have a separate setup for each. Now I don’t dive singles anymore, but I now have separate setups for different environments: cave/shipwreck drysuit dives vs swift water...

I’ll check out the details of what you’re describing, thank you for clarifying. I certainly understand that wherever you draw the line they’re going to be people unhappy with where you have drawn it. :) My point is this: all of this information seems to be completely unknown and un...

Thank you for the suggestions. You’re right: if you forget about local, you could just work on the cloud and it would make things a lot simpler. I’m weird, I guess. I prefer on-prem. I’m far from anti-cloud, but I want control, and independent ability to protect my data. Get off my lawn. :)...

The app is called SubSurface – mobile. You download it from the App Store. Then, you go into subsurface on your computer and go into the settings. From there, you can create a cloud account. That will allow you to push your logs up from your computer to the cloud, and the Subsurface-mobile app...

The only people who can answer that question for you is Catalina. That’s why most people say you have to have them from the same lot, because that’s the only way you can be certain that they are the same. But you’re overthinking it. It will be fine. :) @Dirt Pineapple ‘s point is an excellent...

It’s not ideal. There’s no guarantee how similar the tanks are going to be. When they are the same lot you can be pretty confident they will be similar. But it’s not exactly a rule. I have a set of LP 85s that were made nine months apart. They’re doubled up and have worked fine for the last...

You do if you want the gas to stay in the tank! :) There’s a couple ways people handle that. They either install a burst disk larger than the pressure that they want to use in the tank, or they intentionally disable the burst disk. Back when most burst discs were separate assemblies where you...

That’s the point to take away here. You need high precision and accuracy especially when you are comparing the results to others (or to a standard) and in a situation where small changes will make a big effect. Your compressor has neither of those conditions. First of all, you’re going to get...

I wired up K type thermocouples on my compressor. I used not-adhesive thermal heat sink pad material to electrically insulate the thermocouple from the tubing: a single layer above and a single layer below. I then used a simple wire tie or two to hold the thermocouple tip up against the...

Somebody get that writer a Grammerly subscription! It's like a caricature of a Fortune 500 press release. Press release as satire! You're writing to divers: just write normally. No one's going to buy your unit just because you wrote in passive voice third-person with as many $5 adverbs as...

I don’t want to derail your thread, but this seems like a good place ask: I’ve heard these referred to as Larry Green reels. You are referring to them as Jasper reels by Ralph Hood. Does anyone know the history of the name? ETA: I thought I would add *something* relevant to the thread…. I...

Yup, just a straight-up data entry error. Spreadsheet and PDF are updated and attached here. I'll ask the mods to update the first posts as well.

I’ll be in the Ft. White / High Springs area and diving Feb 24-28. You can see my profile for more details, but I'm a TDI Full Cave diver with about 70 or so post-Full-class dives. I dive backmount exclusively. I'm good up to a single stage and deco, though I'm also just as good spending an...

DM sent.

Yup…. :) Hardest part of diving a drysuit. It’s the combination of the difficulty of feeling the change in buoyancy, and the fact that the actual dump will take a lot more technique and a bit more time to accomplish. So why make that worse by putting more air in that suit than necessary? The...

+1 My fear was a situation like what killed that woman during her training. So, to OP: make sure you test inflate your BC *and* drysuit before you go in the water…

I agree, and do the same thing on every charter I take, in advance before I get on the boat. I’ve had your experience before, and don’t want to repeat it. ETA: Often, you only have to do that a couple of times. If you’re not a train wreck, and are polite and reasonable, I find they usually...

There were a fair number of valves from the 70’s that had HP ports for pressure gauges. Here’s a pair of valves I had asked some questions about: they had gas gauges built into the valve itself...

Yeah, an eCCR with a wireless controller is an interesting juxtaposition for an organization that is at best not supportive of a deco computer, let alone air-integrated computer… (I mean, I didn’t miss any SOP changes, right?). And @PEDiver ’s point is valid: Halcyon is not *actually* GUE…...
