    On using a small tank to increase bottom time and provide redundancy

    Hey all! So, some context: I do most of my diving in 20-40 ft of high current, low vis water. I have a "buddy" on these dives, but realistically, if we're not using a tether (which we do if things seem risky today, but usually not as it's an entanglement risk) we're unable to readily come to...

    Redundant Octos & 2nd Stages Unable to Deliver Air?

    Disclaimer: This is an advanced thread, I do not advocate beginner-to-intermediate divers ditching their octo. In a thread about pony-bottles, the topic of whether or not to ditch your octo came up. Specifically, someone mentioned being unable to access your larger air supply, if you use a...

    Question Redundant gas when traveling?

    I almost exclusively dive back mounted doubles here in Norway, and when I went to Dahab last year I was able to rent doubles, but many places in the world that's going to be tricky. I would prefer having redundant gas and regs in the 60-100ft range, especially when diving with random buddies and...

    Advanced Beginner Gear Grab - Helpful for others too?

    Alrighty then. I've managed to get irritated enough in about 15 dives to want my own gear (more or less) immediately. Like most of us, I have pockets that you can see the bottom of and want to choose wisely. I would consider myself an "advanced beginner" or "beginning advanced" due to...

    Bailout rebreather?

    Hello, rebreather divers! I'm not one of you yet but hope to be as soon as I can scrape together $10k for all the bits and training. I was talking to a young man at my LDS about how I'd been ogling the KISS Sidewinder, and he told me about an instructor who uses it as his "bailout rebreather."...

    Emergency or Incident depends on how you see and handle it

    I posted this on another site so if you have already seen this forgive me. This is a lesson’s learned type of post, as always, I will thank you in advance for reading to the end. I spend a lot of time in the water, many times Solo due to the type and frequency of my non-PSD dives. With this in...

    Liveaboard Mask Redundancy

    I've seen mask straps included in Save-A-Dive kits, but not much else as far as mask parts. I'm signed up for a liveaboard in Komodo. Instead of just buying an extra mask strap, I bought another mask, same brand and model as my current one. I'm wondering if this is enough. I have a...

    What's the deal with H-Valves?

    I have been doing a lot of reading on this forum, and others, and have found a whole lot of negative opinions on the use of H-valves. I'm wondering where all of this is coming from. I see the H-valve as being the best of both worlds: a single tank for simplicity and cost, but dual 1st stage...
