EDIT: the question has been solved. The confusion below arises from the fact that it's not actually a 97 cf tank, it's a 550 cubic inch tank (that could hold up to 97 cubic feet of uncompressed air) Suppose I have a 97 cf tank at 4500 psi, and a 13 ci tank at 3000 psi. Every time the little...

I was living in Boston and often diving every weekend. At the beginning the pandemic, I sold my house and moved into the country, so I haven't been able to dive for a long time. However I'm moving to Hawaii this winter looking forward and looking forward to some socially distanced reef and...

The Wetsuit That Keeps Away Sharks What ever happened to these? They had two wetsuit designs supposedly coming to market, a striped one to make you look like a Banded Sea Krait, and another that was designed to be be camouflaged in the shark visual spectrum, both of which apparently had good...

I am moving to Molokai for about four months this winter, and very excited to go diving there. If anyone has dived Molokai reef, or has info about Molokai diving in general, I'd love to hear it!

I'm used to cold water diving, and my exposure suits thus far are a 7mm semi-dry wetsuit, which I really love for the local Boston waters, and a Fusion dry suit which I bought for the winter months, and a rash guard that I got for diving in Mexico. In preparation for my upcoming scuba trip to...

From what I've read and heard from those who've had it, it seems that DCS symptoms come on fairly gradually, and get worse over the next couple hours. The treatment is hyperbaric oxygen therapy, but time is of the essence, and the longer you wait the greater the risk of permanent damage. In...

I'm curious what things are checked when a regulator is serviced, what type of repairs would be included in a normal regulator service fee, and what aspects are easy to service yourself to reduce the frequency of having to take it in

Did my 4th and 5th shore dives today with the local club this morning. The organizer paired me up with a more experienced diver with about 500 dives due to my inexperience which I was happy for. I felt competent, safe and comfortable, but I recognize my inexperience and welcome learning from...

Got a brand new wetsuit (h2odyessey), and after just 3 dives with it I noticed the substantial fraying in the seams around my waist where the stiff webbing of my BP&W rubs. I'm worried that after a few more dives, the seam might split apart and ruin the suit. Is this normal? Should I have to...

Has anyone tried using spray on superhydrophobic coatings to their wetsuit? eg, Rust-Oleum® NeverWet® Fabric Water Repelling Treatment The coating may not last forever, but I'm thinking it might be a simple way to turn your wetsuit into a drysuit for enhanced thermal protection and reduced...

Currently diving in temps a little under 50 degrees, but I want to be able to dive comfortably in even colder water. I'm wearing a 7mm semidry, with 7mm gloves, and feel warm enough. On my feet, I'm wearing Deep Sea 5mm Echozip and they get uncomfortably cold. What is the best option for...

The risk of shark attacks is low, and the risk of shark deaths is even lower. Usually when sharks attack they take a bite, then let go. With that said, it does still happen, and sharks are attracted to high contrast colors, such as bright white / yellow/ etc that you might have selected for...

I don't like having my peripheral vision constrained by my mask. I'm currently using an Aqualung Mission Midi which fits well, and claims to have a wide field of view, but it's nowhere near my field of view out of the water. Has anyone tried this new 180 degree mask? 180 Diving Mask...

My primary second stage regulator is on a 40" flex hose routed under my arm. I'm looking for a good swivel, so far these are the options I'm considering: 1) for $26, the XS scuba 90 deg elbow: XS Scuba 90° Right Angle Adapter Based on the youtube video, it appears this unit also swivels. 2)...

I am trying to replace the HP hose that goes to my SPG gauge console. The console has a rubber casing making it very difficult to access the attachment nut (I can only seem to get a grip on the rotating nut). I can see the fixed nut underneath but can't seem to get a pair of pliers in there...

Assume that one carries just enough weight to be neutral at the safety stop when the tank is near empty of air. That weight is critically important to prevent a runaway ascent, so it would generally be a very bad thing if, for whatever reason, one found themselves low on air and then also lost...

I got an Aeries XR1 dive computer basically for free. This is my first dive computer (I have never used one before). It's in like new condition and came with all the original manuals and paperwork etc. I know it's not the latest and greatest, but then again I didn't spend hundreds or...

As a beginner diver, it makes me a little nervous thinking about my tank valve knob, being out of sight, which could either be bumped (perhaps repeatedly, eventually causing it to become closed), or potentially ensnared in some line/netting/etc such that my movement closes the valve...cutting...

I recently just purchased my first tank, a Faber HP100 @ 3442 PSI. I purchased it from LeisurePro: Faber High Pressure Steel Tank Bouyancy characteristics are listed here: https://www.leisurepro.com/api/getSizeChart?productId=FBRHP In summary: Weight: 34.3 lbs Bouyancy full: -8.41 lbs...

Looking for a noisemaker to get attention of dive buddies. A few options I'm looking at: * XS Scuba Rattle Stick. I like that this is small, comes in a black version (not shiny), has a magnetic stopper. Not sure how loudness compares to the others XS Scuba Rattle Stick with Attachment Clip *...
