The guide/instructor/buddy will take care of me.

It’s amazing to many of us how easily supposed well-trained divers can turn into “sea sheep,” simply following the herd without asking simple questions like, “where are we going, and how long will we stay?” All too often, divers regard dive guides as unerring, and will simply follow along. And while most of the time professional dive guides will be sufficiently conservative as to avoid decompression obligations, there are exceptions. According to the latest DAN data, 7 percent of the 348 divers injured in 2002 were relying on someone else rather than the tables or their own dive computer. What were they thinking? The take-home lesson for our students is that each of us is responsible for our own safety, and that means doing our own planning.

Other diving myths revolve around physiology and the physics of diving. Here again, we find some common myths and misconceptions that should be cleared up.

The exclusive Optical Ocean Sales YS-01 S-Tray Lighting Set is the answer for underwater photographers that want a great quality, fully-configured underwater camera system. Includes the ergonomic, adjustable S-Tray with integrated handles.

Compatible with most point and shoot underwater housings from major manufacturers (except Ikelite) that use a tripod-mount screw, including Canon, Olympus, Fuji, Fantasea and Panasonic.

The S-Tray is made from black anodized aluminum and is a medium weight system. It features a 3-part tray that can be easily adjusted for different sized housings, hands, gloves or shooting styles.  Interior width expands to approximately 11.75. The S-shape of the foam covered handles conforms to your hands while gripping the housing, and is very comfortable and relaxed to hold. The tray includes two base to ball connectors (OOEC-06).

This package comes with a fully-adjustable modular ball and joint arm system (OOARM-01) and an extra YS mount arm and clamp to hold a focus light. The YS mount fits any Sea and Sea or Fantasea strobe and focus light, adapters are available for Inon or Ikelite strobes. Ball and joint arm systems are much stronger, adjustable and will stay in one position better than flex arms. You can expand this with extra arms and a triple clamp (#3013) to fit a second strobe, as well as the focus light.

Included is the Sea & Sea YS-01 strobe and fiber optic sync cord. It has a guide number of 20 and features 10 steps of manual power, D-TTL auto operation and a target light. Also in the package is the small, powerful NanoFocus Light (6022) to allow you to see and frame easier, as well as allowing your camera to focus faster. This is essential for the lower light situations found underwater or for night diving.

You can upgrade the focus light to the excellent and much brighter Big Blue 1x5 AFO which has a wider beam and is more useful for night diving or in temperate waters.
