Digital Camera Fully Compatible, Newly Developed S-TTL System
Digital Camera Fully Compatible, Newly Developed S-TTL System "S-TTL" enables TTL auto shooting by an external strobe for a digital SLR camera as well as for a point & shoot digital camera. INON S-TTL auto strobe supports any manufactures' model providing highly accurate exposure control. Film camera era without strobe selection problem TTL stands for "Through The Lens" and TTL auto strobe system controls flash amount to provide correct exposure based on calculation by camera's internal sensor metering reflecting strobe light from a subject through the lens. This TTL system meters actual light amount reflecting from a subject providing accurate exposure. When we start with the history of underwater TTL auto strobe, underwater camera "NIKONOS V" released in 1984 was the first to provide automatic TTL flash control for underwater strobe SB-102, SB-103 succeeded by NIKONOS V compatible underwater strobes form other manufactures. The 5 pin electrical sync connector for NIKONOS V is most popular and widely adopted to connect an underwater strobe and underwater film camera (underwater camera / housing). A film SLR camera has flexibility to select an underwater strobe. As far as housing has NIKONOS type electrical sync connector and properly NIKONOS type 5 pin electrical wired, automatic TTL flash control is usable with any TTL auto strobe sync connector and NIKONOS V like Nikon SB-105, INON Z-220, Z-22 connected via electrical sync with INON Z-22 strobe cable. Film camera compatible strobe is not usable for a digital camera!? Underwater TTL strobe circumstances have been drastically altered with the spread of digital camera among divers. -
DAY TRIP Submerge Yourself
DAY TRIP submerge yourself magine water of such astonishing treasure: crystalline springs fed by clarity that fish seem to hover in underground aquifers. Springs so mid air, suspended motionless pure that the water is now bottled for against a backdrop of blue skies and drinking purposes. But what makes shade trees. Then visualize a cavern these springs so unique is not only the 50 feet underwater, where sunbeams clarity of the water but the fact that they dance over the cave floor and visitors team with life. The springs play host float motionless in liquid space; a world to bream, gar, bluegills, catfish, eels, where gravity ceases to hold sway and the and bass. And for snorkelers, SCUBA temperature never varies by as much as a divers and kayakers, the abundance of single degree year round. Now, imagine life in the springs offers the opportunity yourself immersed in the fluid embrace to swim and dive in a world of of this marvelous world. Sounds like the unparalleled beauty. It’s a chance to product of an escapist fantasy, you say? experience one of Florida’s greatest Could be. But while the effects may be natural wonders. surreal, these places do exist outside the Florida has the greatest concentration imagination. And they’re only hours away of freshwater springs in the world. In in nearby Florida. fact, there are 33 “first-magnitude” Renowned as a dive mecca, Florida is springs alone (discharging at least 100 famous for its endless beaches and clear cubic feet of water per second). And waters. When most people think of there are hundreds of lesser springs SCUBA diving or snorkeling in Florida, that provide endless possibilities for they think in terms of saltwater. -

Adm Issue 10 Finnished
4x4x4x4 Four times a year Four times the copy Four times the quality Four times the dive experience Advanced Diver Magazine might just be a quarterly magazine, printing four issues a year. Still, compared to all other U.S. monthly dive maga- zines, Advanced Diver provides four times the copy, four times the quality and four times the dive experience. The staff and contribu- tors at ADM are all about diving, diving more than should be legally allowed. We are constantly out in the field "doing it," exploring, photographing and gathering the latest information about what we love to do. In this issue, you might notice that ADM is once again expanding by 16 pages to bring you, our readers, even more information and contin- ued high-quality photography. Our goal is to be the best dive magazine in the history of diving! I think we are on the right track.

Missouri Speleological Survey President's Message October 2018. Despite the foreboding forecast of biblical rains, the Fall MSS meeting at Current River State Park was a great time. Before the weekend began, we had a long list of objectives and a sizable group of cavers expected to come, as well as ambitious plans for a large map and gear display for the public. Weathermen across the region however, conspired to keep people home with predictions of heavy rain throughout the weekend and flash flood warnings across the state. As the weekend drew nearer, the number of cavers bowing out increased by the day. Nevertheless, while it did rain all day Friday and poured on us during the drive down Friday night, the rest of the weekend was fairly dry and beautiful. The Current didn't rise, so one small group monitored caves via kayak and a much larger group went to Echo Bluff State Park to work on graffiti removal, left over the Camp Zoe events, as well as to perform a bio survey, per request of the park, to see whether the cave closure had any noticeable impact on the presence of cave life.
