Great portable light table!

Thinlite Portable Light Table

Awesome focusing light!

     Here's a product introduced to us by one of our guests. This is a really cool little portable light table. It's about the size of a single slide sheet and, as the name suggests, it is very thin and light.  The light quality is exceptional, with a uniform, bright, color correct light. What's more, unlike it's closest competitor, it does not require a somewhat heavy accessory power supply. Plug it in, turn on the switch, and you have a nifty traveling slide viewing and editing table all your own. No more violent, eye-clawing, ear-biting, kicking, nostril ripping fights for a turn at the light table on your next live-aboard trip. Now you can have your own private editing suite in your cabin, so you can suffer and cry in private. We're not dealers, but we can certainly help you get one if you can't find one on your own.

Light in Motion Sun Ray Mod Light

     A good focusing light is a necessity for night diving obviously, but equally valuable for day diving when shooting macro and where the subject may be in the shadows, in deeper darker water, in a cave or under a ledge, when using ultra high magnification lens combinations where the bellows effect is significant, or in any situation where you wish to see the a reasonable facsimile of the actual colors and color relationships in a scene for composition decisions. Trouble is, most diving lights adapted for this purpose are crude tools. The color temperature of such dive lights are generally very low, imparting a very yellow, yellow/orange cast to the light, distorting the true color relationships. What's worse, the reflectors are normally so unrefined, the illumination is highly uneven and is a mottle of hot spots and shadows which can make critical focus actually more difficult at times. As well, the beams are often very narrow, requiring constant re-aiming as the subject distance changes even slightly. Lastly, dive lights of sufficient power and burn time to be of any legitimate use have traditionally been overly heavy and bulky.

     Enter Light in Motion's Sun Ray Mod light.  It's tiny really, not much bigger than the palm of your hand, and feather light both in and out of the water.  The halogen bulb provides a very ``white light" and the reflector is superbly  designed to give extremely even wide beam illumination. With the wide beam, one can, within reason, set it and forget it, in terms of aiming.  Only major changes in subject distance require repositioning of the light, and even then the re-aiming

process is very quick, as precise accuracy is no longer important. Combined with a super light-weight, flexible bubble arm and shoe mount base, and you have the ultimate in quick positioning. A single button controls on, off, and a three range power setting.  The bright setting gives a very intense illumination and a shorter burn time. Whereas the medium and low settings will increase burn time while decreasing the illumination. The lower settings are great for light shy subjects, while high power is instantly available when extra brightness is needed, say for strongly back lit subjects. We find the lowest power setting more than adequate for normal work, and get well over an hour of steady burn time at this output.

     The only negatives with this light are that the battery pack is built into the light, so when the light needs recharging, it is out of service until recharging is complete. The second negative is the cost. It is the priciest focusing light you're ever likely to consider.  However, we, like most of our guests who we have turned on to this light (no pun intended!), have ended up getting two in spite of the cost. They are that good.  And once you use them, it is nearly impossible to go back to the trusty old dinosaur light.

Ikelite DS 125 Strobe

Best all around strobe we've seen!

     We've just started using this great new strobe from Ikelite. I LOVE these strobes! The DS designation refers to ``Digital Strobe", which means it has the pre-flash features required by certain digital cameras.  However, it works perfectly well with standard film cameras.  It is powerful, compact, and lightweight on land and in the water.  The feature I like best from a photographer's point of view is its blazingly fast recycle time.  One second.  That's right:  one second for a full power recycle!  Just imagine how beneficial this is when shooting behavior sequences for instance, where the behavior you're trying to capture may only last a few seconds? If your strobe takes 4 seconds, 10 seconds or even more to recycle, you'll get only one shot and miss the sequence entirely.  Or when shooting wide angle reef scenics of say, sea fans, and unexpectedly a manta is sailing through your background.  The ray may only be in position for 4 or 5 seconds.  If it takes your strobes that long to recycle (or longer in many cases), you'll get but one shot.  Not so with the DS 125.

     The shooting modes of the DS 125 include TTL or manual, with a 4 setting, 4 stop manual strobe power setting range of Full, 1/2, 1/4 and 1/8 power.  It sports a slick ``fuel gauge" to indicate the remaining battery power, along with a modeling light.  The rechargeable battery pack comprises the entire back half of the strobe, and it is very quickly and easily removed for recharging or exchange with the simple lift and rotation  of a single lever.  The front half of the strobe, containing the flash tube and

electronics, is completely sealed so any possible leakage from the main seal will not affect the most critical part of the strobe.

The only accessory light meter worth owning!

     In these days of increasingly restrictive baggage allowances, this new strobe from Ikelite is a real winner, but the photographic benefits of having such a fast recycle time make the DS 125 an invaluable tool for the serious photographer.  This strobe comes very close to being a ``one strobe does it all" unit, ideally suitable for both wide angle and macro. Ultimately, it does not have the maximum power of its older cousin, the Ikelite SS200 strobe, so I judge the SS200 a better choice specifically for wide angle. Yet, the SS200 is noticeably larger and heavier, therefore not nearly as suitable for close up work. So in this regard, in my opinion, the new DS 125 is the best ``all around" strobe in Ikelite's rich line-up of quality strobes.  And remember, you can get these from us and save money!

Ikelite Digital Light Meter

    It's been around a few years now, but I've never commented on it before. We love it! What a winner! It's the best underwater light meter on the market.  It combines a reflected light meter, incident light meter and flash meter with a digital read-out display featuring big, bold easy to read numbers.  The meter is compact, easy to operate and an essential ingredient in our wide angle photography.  It is highly accurate, and the use of the Ikelite digital light meter combined with a basic understanding of what a light meter is trying to tell you, will assure nearly perfect blue water readings with every shot.  Don't leave home without one!

     Note:  accessory light meters are of value only for wide angle ambient light or combination strobe and ambient light photography.  The bellows effect of macro lenses render the readings of an accessory meter inaccurate, whereas the TTL meter within most cameras will take into account any bellows effect.  Buy from us and SAVE!

DataMax Pro Plus Dive Computer by Oceanic

The diver computer for thinking divers.

     When Orca stopped making dive computers, I didn't exactly think it was the end of the world. Just close. This was the one brand of dive computer that gave a serious diver reasonable bottom times while allowing the cautious diver the option of building in their own conservative safety margins as they felt appropriate for their personal physical condition or DCS risk factors. Much as a skier is free to chose the difficulty of run they descend with the understanding that the chance of an accident increases along with the pitch, terrain factors,  snow conditions and snow pack stability, the diver could make their own adult decisions regarding their exposure to decompression sickness risk.

     Ah, I long for the good old days of personal responsibility, now but a distant memory in our society.  Happily, we have found one computer that offers the best compromise on this issue that can reasonably be expected in today's litigious, predatory personal injury lawyer saturated world. That would be the Oceanic DataMax Pro Plus. The one sure way to avoid decompression sickness of course is to limit your diving to a single tank of air in your bath tub once a week, and some of today's computers seem to be programmed with that mentality in mind. The DataMax Pro Plus balances a high emphasis on safety in an intelligent way, resulting in a computer that gives respectable bottom times while permitting the diver to increase their margin of safety as they wish.  It is air integrated, Nitrox programmable, and features large, easy to read numbers with a clean layout.  It is packed with information, but never cluttered with data of marginal importance.  Secondary information (time, date, water temperature, etc.) can be accessed on an alternative screen at the push of a button. Bottom line:  this is the very best dive computer on the market. Add the small, inexpensive hockey puck style Oceanic DataPlus as a back-up, an you are good to go for long duration dive tours.
