    Two more dive physics problems

    I don't answer these questions for people because; a) they should be working out their homework themselves, b) I live in the part of the world that uses sensible units (metric)

    What Would You Do?

    They were unnecessarily harming sea life, damaging coral, and generally creating an unsafe nuisance on a training dive. My initial reaction when I first saw the thrashing around out of the corner of my eye was that someone was in genuine trouble or having a panic attack, that's what got my...

    Nirvana, Extremely well put, sensible and constructive answer. Thank you for putting into words what I would have liked to say.

    What is the problem with doing a Scuba Review/Refresher?

    Interesting topic because this year I fell into this category completely. Been diving for 3 years, logged 26 dives with the last one 11 months ago. So on the first day of our summer holiday this year, I pre-booked myself and my daughter up for an official refresher dive at $75 each. For that...

    What Would You Do?

    You are right, I missed my opportunity because we came up a couple of minutes ahead of them, damn!! On a more serious note, after considering what peeps have replied above, this morning I drafted and sent this email to Lee Webber, the president of MDA...

    What Would You Do?

    The final one who touched the "ball" appeared to "spike the touchdown" which is not done in those other games.

    What Would You Do?

    Wasn't sure where to post this - mods please move if you wish.... This scenario happened last week in Guam diving off an MDA boat in Apra harbor with 20-25 people on board. I dive regularly (every summer vacation for the last four years so stilled haven't racked up so many dives), and some of...

    Oceanic Geo 2.0 Firmware Update Failure

    Had my Geo 2 about 18 months now and I already updated the firmware to r1H last year, then noticed recently that r1i was available. Used the same routine of update via the Oceanlog software and it reports a failure at the end. However, the PDC reports it has r1i on board and all appears to be...

    More Specific ID of a Sea Cucumber Requested

    I managed to get this rather nice shot of my daughter examining this multicolored sea cucumber at Finger Reef in Apra Harbor, Guam last week. Can anyone offer a suggestion for the common or scientific name of this type. Saw many of the more common black type of course, and a lesser number of...

    Diver dies searching sunken South Korean ferry

    I can't remember where I read it but I saw that the dive recovery team consisted of well over 500 divers working in shifts due to limited bottom time. It's no excuse but maybe puts into context the number of incidents that occurred. I live in Japan and in many ways Korea has a similar...

    S120 or G16, ikelite or Canon housing....??

    For the last five years I have only used plastic housings by camera makers, currently a WP-DC38 for the Canon S95. I prep the seals well, use desiccant and have never had a trace of leakage or condensation. Leakage is far more likely to be user error

    Inon S2000 + InonZ240 - Too much power difference?

    For the last couple of seasons I have been shooting with an S95 and a single Inon S2000 because that was all I could afford at the time. Since then I have been shooting mid and macro shots and gaining experience. Now I want to experiment with my new wide angle lens so in the near future I hope...

    Silent computers?

    My Oceanic Geo 2 has alarms turned on - sorry if that offends anyone. It also has a red LED that flashes when an alarm is sounding. We are all human and humans make mistakes - even those that are much more experienced than me. Just take a look at the accidents and incidents board for proof of...

    Canon S95 vs Canon S120 Image Quality

    Thanks for the feedback. On the specs at least, the S120 is a major step up with faster and more accurate low light focusing, up to 12fps, and an improved sensor and full HD video. I know the fast frame rate is not going to help when waiting for flashes to re-charge but at least it suggests...

    Inon Lens Mounts Changeable?

    Thanks guys for the feedback. This is useful stuff. I understand the benefits of the LD bayonet, especially for the UWL-100 because, man that thing be chunky. Just want to expand my options a little.

    Inon Lens Mounts Changeable?

    Hi All, I have invested in the Inon LD series for close up and wide angle lenses. The LD bayonet system so far has a limited camera compatibility and I am wondering if there is the possibility to convert the following lenses; UCL-165LD, UWL-H100LD to another mount such as the AD mount or 67mm...
