    How do you insure your U/W DSLR set up?

    Mine are on a rider with the home contents insurance. With Nationwide this turned out to be much cheaper at the time than a DAN partner.

    Moving to Boston

    Welcome to the area. There are plenty of opportunities to dive out here - from shore dives to deep technical wrecks . Many of the shore dives are within 30 minutes drive time from Downtown Boston out on the north shore and there are a number of charters running in the area for both Tech and Rec...

    recently certified, got lots of random questions

    Looks like we've hijacked a thread. Ok, how can I make this any clearer? The GoPro MUST have a flat port for underwater use if you want anything approaching the HD quality the camera is capable of. Granted this reduces the FOV a little but it's still more than wide enough to capture a useful...

    recently certified, got lots of random questions

    That footage is horribly out of focus and is a classic reason why GoPros underwater MUST HAVE a flat port. Yes, it's counter intuitive to most underwater photography but in this case, there's no debate - it must have a flat port. On the surface, the flat port isn't too bad but I run two cases...

    GoPro Anti-Fog Inserts: Really Necessary?

    Nope. I've dove with the camera in the cold north east, including quarries at a constant 42 degrees F - never had a moisture problem. I used to stick the camera and case in a ziploc bag with some large desiccation packs and assemble them in the bag ahead of a dive but haven't done that for about...

    Is a super computer needed for gas switching?

    Yes, many times. It takes a few breaths and a short delay to get the drop indicated so I always use the visual check, plus all my tanks are backed up by an SPG that allows a very rapid drop to registered by turning the gas back on, off, take a breath and watch the needle drop instantly. Having...

    Is a super computer needed for gas switching?

    Plus, the transmitters on the Sol aren't sending the pressure info fast enough to make this a reliable indication at the switch depth. They're no replacement for a visual check of what you're ABOUT to breath BEFORE you stick a reg in your mouth.

    Martini Effect -- No Consistent Definition

    It's as subjective as a martini itself - how many martinis you've had in the past, if they were Swedish martinis (gone in one gulp) or NYC martinis (the size of a fishbowl) (and let's not even debate if they're gin or vodka martinis ;-) ). Narcosis is dependent on so many things - physiology...

    Do we need more hand signals?

    Easy, grab your buddy's fin (or BC strap, or octo etc) and don't let go. That generally slows people ;-)

    Is a super computer needed for gas switching?

    It's only intellectual in as much as decompression theory is just that... a theory. Well tested, but still with large gray areas. There is always a risk to diving mixed gases but that's why it's all planned, trained and prepped for ahead of time. The gas switches normally occur on the way to...

    Question about Integrated Air Computers

    That's simple... YOU are responsible for your own safety and should be checking your loadings. I don't believe the live aboard crew act as a mobile branch of the Scuba police.

    Is a super computer needed for gas switching?

    Correct. Nitrox is used to either extend the NDL or increase the safety margin by diving it as air (having burned the MOD into your brain, or set the depth warning on the computer). It is also used to accelerate decompression by switching to it at the correct depth. Being a cold water diver, I...

    Question about Integrated Air Computers

    I can't speak to the Oceanic integration wrt reliability because all of my transmitters etc are Scubapro. While they occasionally drop a connection during a dive, they do reconnect quickly so I've never experienced a failure. I do carry a backup SPG on all tanks being carried to facilitate...

    Is a super computer needed for gas switching?

    I'd be more amazed if a computer these days *didn't* have nitrox already baked in, at least as a single gas (don't confuse nitrox ready with multi-gas ready). It's a very small step from OW to nitrox since there are few new skills involved and the benefits are extensive. A 'good long while' to...

    Is a super computer needed for gas switching?

    Yes, you need a multi-gas computer that factors in the gas mixes and by design, these will support the switching of gas (the process is 'switch gas then tell the computer') and most will prompt the diver with various alarms, including a depth warning should the diver descend back past the MOD...

    Is there any wreck diving in New Hampshire?

    There are a number to choose from out of Cape Ann or Boston. NH itself is more about shore diving and the lakes. Check out Northern Atlantic Dive Expeditions on their boat "The Gauntlet" or Cape Ann Charters on "The Daybreaker" (though the boat isn't back in the water until later this year) or...

    Where to strap a small knife

    Hi Fred, Strapping a knife on the inflator hose is fairly common and makes it easy to reach - the hose is generally quite robust and a couple of zip ties is enough to hold the knife scabbard without collapsing the hose. It does add to the drag though so when I'm wearing a BC, I place a small...

    where is the best place to dive on east coast?

    I'd have to say anywhere from RI through ME... but then since I live in the area and can splash within an hour of leaving my house, I would say that ;). Doesn't really depend on what you want because we've got shore dives, wreck dives, shallow dives, deep dives, scallop dives, bugs, fish...

    A question about the Partial Pressure of Oxygen

    Hi Matt, These are all good questions. On the first one, a tech diver is a diver who is PLANNING to not be able to escape directly to the surface should an emergency arise. This could be because they're inside a shipwreck, they could be deep in a cave system or may have a deco obligation...

    Go pro or other

    It really depends on what you want to shoot... I use a GoPro to record various tech and rec dives when it's more about the dive than the movie (as long as I remember to move my head slowly). If I want to focus on the video or stills, I'll take one of my Canons in a housing down (and probably...
