    Advice about diving in Atami

    I've found the currents in Atami to be pretty mild. Sodaine is also a very nice site, but with just two of you, you're probably going to end up going wherever the boat wants to go. You wouldn't need a guide on Chinsen (just watch your gas consumption) unless you traverse to the stern...

    Best Safety Stop Depth

    Just my opinion, but I think the best safety stop is a 6 minute ascent from 20 feet/6 meters.

    New angle on Japanese dolphin issue

    Thanks, X. OT, but I highly recommend the (1977 Pulitzer Prize winning) book "Beautiful Swimmers" by William Warner. It's about the Blue Crab in Cheapeake Bay. I've loved the Blue Crab ever since I read this book 20 years ago. Beautiful swimmer is the translation of it's Greek name, and it's...

    New angle on Japanese dolphin issue

    This is an issue that a lot of people get worked up over, with nearly all of the comments coming from outside Japan. Here's an interesting article that I came across last time I was there - published inside the country, albeit for an English-language readership. It's well worth a read, both...

    advantages of getting a DM - is it worth it and why

    You may not have NAUI courses available to you through the club, but this advice is spot on. The NAUI Master Diver rating is very far beyond and really nothing like the PADI Master Diver "designation." You will learn a great deal about diving through this course. I'd also suggest the GUE...

    First unguided dive goes badly

    I agree with the earlier posters - you were trying to add too much at once to your experience base. Why not think about your next few unguided dives on a shallow reef where you can correct navigational errors more easily? As for your question, what you could have done differently is respond...

    Scubapro G500 + Nitrox

    I'm not telling you to throw any old parts in there, but I believe that problems with O2 tend to occur in the high pressure part of the system - tank valves and first stages - not the low pressure side. Think about it this way: is your BC built with oxygen compatible parts? Last I checked...

    Don/Doff BP/W

    It will take some getting used to if you have been diving a jacket BC with adjustable straps. It's possible you have the straps a bit short. As long as you don't go so far as to have it flopping around on you, why not try feeding a bit of webbing back through from the belt on each side? I...

    Free Flowing Scubapro

    That is a terribly unsafe reg and you should send it to me immediately to keep yourself out of trouble. :D Just kidding. Are you talking about slight bubbling from the second stage or a real free flow? If it's the latter, the advice sounds like hogwash to me. A regulator that is good...

    Anyone here sticking with analog gauges?

    Analog SPG for me. They are simple and reliable. I wear a computer or usually a bottom timer on my wrist. I don't want to introduce electronics into my information on breathing gas.

    HydroOptix or Prescription Mask?

    I tried the HydroOptix, which as you say is a neat concept, but I didn't like the volume of the mask and the steps required out of water. I went with either wearing disposable contacts with a regular mask (preferred, use most of the time) or a mask with prescription lenses (use when cave...

    Some IOP pictures from last weekend

    That's probably your slug, then. And there is very little English in the book. Pretty much just the Latin names and the lengths in mm. Great pictures, though, and with a little work you can work out the kanji for where the pictures were taken.

    Some IOP pictures from last weekend

    Based on the general body configuration, the size, the Izu location, and in particular the pattern of barring on the oral tentacles, the closest I can come to your nudibranch is a Pteraeolidia ianthina. This in no. 591 on page 268 of the book Opisthobranchs of Japan Islands by Nakano Rie, and...

    Some IOP pictures from last weekend

    Geoff, do you recall how long that nudibranch was?

    Some IOP pictures from last weekend

    Hey Geoff, Fun pictures. IOP can be a great spot, it's just a shame that they limit the access the way they do. The eggs are from a nudibranch, what specific type I don't know. But I've seen that type of spawn before around Izu. I don't have my guidebook here at work, but I believe...

    Martha's Vineyard?

    Anyone on here done any shore diving on Martha's Vineyard? Any advice? The family won't tolerate me taking a boat, so I'm just looking for shore dives. Thanks!

    "You're gonna Die"

    Wow, you couldn't have scripted a better learning opportunity. Did your instructor set it up? That is a very lucky team. Navigational errors in caves - and in Mexico in particular given the complexity - are pretty damn unforgiving.
