I'm looking for a dive knife where the sheath is of the style with a "button" release and can be attached to a standard 2" webbing. Additionally, not too big, so in the mid-size range, say approximately 4" blade. Best example I can provide is the ScubaPro Mako, but I don't think it attaches to a...

Hello, Let's try this here with regard to rebreathers (CCR) although I must admit my personal motivation is for freediving. Let's just generalize the reason for wanting to use a Pulse Ox underwater in order to prevent of hypoxia. I have found a number of medical articles on this subject...

Are there any where diving or snorkeling is actually allowed? It's unequivocally: STAY 300' AWAY! These are a hotbed for marine life as is indicated by the live transmission below, or the article a few months back in the SCUBA magazine regarding diving Ft. Lauderdale's pier, for example...

Background: I have about 100 dives under my belt, but mostly from about 10 years ago. I started back up last year by building my first BP/W rig, piece by piece. It's completed and I have been experimenting in the pool. But. Unfortunately the first time diving in the pool, I experienced a...

Just curious, can someone identify the regs used by the US Navy Dive School in this video? Look a lot like ScubaPro 109 knockoffs to me, but I know nothing about what they use. Skip to 2:02 in video for quick reference.

At the risk of getting beat up here, allow me to make a case where Spare Air or equivalent might make sense. And no, I do not own the unit. Below are the very specific conditions I had in mind whereby it sounds reasonable to me. There may be others (e.g., buddy separation, etc.). 1. Solo...

Perhaps this will ultimately be a silly thought, but it has crossed my mind enough to ask around. There are certainly scenarios for a solo diver -- or any diver really -- where a CESA is the only answer. I have always wondered however, what if the failure occurs at the very end of an exhale? Are...

Would there be any issue diving without the inflator hose attached? Other than not being able to power inflate of course. And not forgetting to plug the first stage mind you. I know very little about the connections on the wing. Is water likely to enter the wing with the hose off I suppose is...

I'm having trouble fitting an LP hose to my used Scubapro g250. It seems as though the protruding center cylinder (don't know what else to call it) of the LP hose is running into the orifice of the 2nd stage. See gap between retaining jam nut of the 2nd and the hose nut when screwed in. Is this...

Pardon, still new to all this. I tied a few bolt snaps to various components, then after I got them wet, the string -- not surprisingly -- expanded somewhat and became loose. Once it dried out, it did tighten back up a bit, but this begged the question: does anyone wet the line before...

Regarding my new ScubaPro MK17 DIN with attached "dust cap": it has no threads?? How the hell does that prevent water entry? At least for a yoke valve you can squeeze the cap in down. Then the manual says rinse with the cap on but no mention of Yoke versus DIN, big difference in my mind. I know...

Is there any issue with depressurizing the rig after a dive, leaving everything connected, transporting the rig home, repressuring, then rinsing? This is intended for pool sessions. Anybody transport their rig in the car with it assembled? Do you lay it flat or upright? I assume straps are...

Preferably one that's ready to go with new poppet; however, I would entertain buying one that needs upgrades / parts. Thanks. -- David davidwlandgren@gmail.com

I ordered the Faber steel tank FX71DVB shown in the table below. The specifications indicate 24.7 lbs as the weight, but I get 31 lbs when I weigh the tank. I assume the valve and boot may add another 2 lbs or so, but over 6 lbs seemed a bit much. The tank seems to be empty. I did get a small...

In looking at schematics of the s600 vs. the g250, the two ScubaPro regulators look pretty darn similar to my untrained eye (e.g, the poppet is the same). I know the more modern g260 is certainly heavier than the s600. I'm assuming the additional metal is the culprit, intended more for cold...

Like the title says, what is the approximate weight of your warm water rig? Why do I care? I plan to do a good bit of shore diving and I am a little concerned about carrying the weight longer distances. I have a moderate back problem and I want to experiment during the work week by working up to...

I say "guess," because a proper weight check should be performed, but I need the guess for an initial purchase. Background: I only plan to do shallow warm water diving in the future. Despite that, I have a BP/W setup with stainless steel backplate, because I want to minimize lead on the waist...

Quick question: If you purchase a tank over the internet, does it typically have recent servicing? For example, if I bought this tank from LeisurePro? Thanks. David

Hello, That's a mouth full. I'm looking for a secondary second stage that is simple (relatively fewer parts) and easily broken down (without proprietary tools) in order to better understand how second stages work and to perhaps perform minor maintenance with myself. It needs to be reliable and...

Hello, Anyone have experience with these custom DGX SPG units. If so, thoughts or experience? Looking for a brass-and-glass for my BP/W. Thanks, David
