Your instructor’s years of experience in technical diving as well as training others is paramount.Whether diver or instructor course, learning comes from exposure to a multiplicity of conditions, equipment configurations as well as true failure situations.We attempt to mitigate all potential failure, but as in the other areas of life, failures still occur. Be prepared

nice “fins on” ladder to swim platform for easy boarding.   multiple GPS receivers LORAN multiple VHF radios multiple depth finders multiple tanks of O2 both Captains trained in O2 rescue, CPR, and  both  are dive masters Please join us for a day of diving off the coast of Maryland or Delaware.

We make every effort to complete ALL lectures prior to any travel to complete dives. This scenario can reduce any time out of town and away from work OR gives the student additional dive time with the instructor.

Advanced nitrox diving provides access to Nitrox mixes from 21% to 100% oxygen at 1.5 PO2 for decompression.The use of multiple mixes of gas in a single dive provides access to safer diving profiles in an extended range of operation. This program is designed to expand the divers knowledge in the use of Nitrox and

Helium is the 2nd most abundant element in the universe and wasn’t discovered until 1868, when it  was discovered during a solar eclipse. Helium is a product of normal radioactive decay deep in the earth. Few places have the right geological conditions to keep it from escaping from the ground into the air. The LaBarge

1917 – Draeger produces a true scuba system that combines tanks containing a mixture of compressed air and oxygen (oxygen-enriched air) with rebreathing technology. It is sold for use at depths to 40 meters (130 feet).1918 – The Ogushi Peerless Respirator passes field tests at 324 feet. The Japanese device combines modified false-lung style closed-circuit
