Local Diving

Many divers are not aware that some of the world's best wreck diving is right here under their noses. The area South of Long Island and East of New Jersey is known as Wreck Valley for good reason -- it's littered with ship wrecks of every size and description. It's a very different kind of wreck diving that what you may have experienced on vacation in the tropics, but we think it's about the most exciting diving there is.

There is something for just about every diver here in Wreck Valley. Whether you're interested in sightseeing, observing marine life, exploring wrecks, collecting artifacts, hunting, photography, or you just enjoy being in the water, you can do it here.

The local diving seas on lasts from April through November, though some people dive year round. Numerous boats in Brooklyn, Long Island, and New Jersey visit wrecks between 20 minutes to 7 hours away on Saturdays and Sundays; some boats also go out on Wednesdays and Fridays. There are also many opportunities for beach diving. If you prefer fresh water, Dutch Springs is a great destination to start with. A day of local diving takes you to a completely different world, and is like a mini-vacation.

Technical Training available through Gotham Divers


Advanced Wreck

This course provides the training and experience to competently conduct advanced wreck dives, penetration skills and techniques are covered.

Advanced Nitrox Diver

This course examines the use of EAN 21 through 50% (oxygen) for optimal mixes to a depth of 130fsw/45msw. The object of this course is to train divers in the benefits, hazards and proper procedures for utilizing EAN 21 through 50% (oxygen) for dives not requiring staged decompression. (Decompression techniques may be combined with this course at the discretion of the instructor).

Recreational TriMix

An introduction to the use of Helium in your breathing gas. Narked at 90 is a thing of the past! Heavy emphasis is placed on buoyancy and controlled ascents.

This course is a pre-requisite for Advanced Recreational TriMix.


Advanced Recreational TriMix

A direct continuation of Recreational TriMix this course extends diving depths using Helium and introduces the use of Nitrox as a deco gas.

Advanced Recreational Trimix Diver & Decompression Procedures

This course examines the theory, methods and procedures of planned stage decompression diving. The objective of this course is to train divers how to plan and conduct a standard staged decompression dive not exceeding a maximum depth of 150fsw/50msw when taught with Advanced Recreational Trimix. Deco gasses up to 100% O2 will be used. The most common equipment requirements, gear setups, decompression techniques and decompression mixtures (including oxygen and nitrox) are presented. For more information, see:
    Advanced Recreational Trimix

Technical Diver

This Program is designed to train divers to conduct dives to depths between 100 fsw (30 msw) and at the instructors option upto 170 fsw (51 msw) using custom blend breathing gas mixtures; and to provide greater understanding of custom blend breathing gas mixtures, a complete knowledge of the limits of any EANx mixture, and the use of EANx and oxygen for decompression.

Normoxic TriMix Diver

This Program is designed to train those who wish to dive to depths between 130 fsw (39 msw) and 200 fsw (60 msw), but who do not wish to breathe air below 130 fsw (39 msw). Trimix affords a means of reducing narcosis on dives to such depths.


Helium and diving were made for each other. You don't have to be a super tech diver to enjoy the benefits of helium. Breathing high partial pressures of Nitrogen is dangerous and hard on the body, so why do it? Replacing nitrogen with helium is a reasonable thing to do for single tank dives as shallow as 100'. What helium does for the 140-170 foot range (previously "deep air") is nothing short of miraculous. You remember the dive, you perform well under stress and you feel better after the dive. Helium is our friend :-)

Regulator Service Technician

We will teach you to break down, service and overhaul your regulator. Since we believe that these skills might come in handy while on a dive, we emphasize field repair.

Trimix Gas Blender

This class is intended to explain the standards, properties, equipment, oxygen safety, handling procedures for blending mixed gases.
