Cavern Diver

This is a challenging and very exciting course that includes four training dives over at minimum of two days. During your first open water dive you'll practice line handling, reel use and emergency procedures without entering a cavern. But, for your next three dives, you're headed into the cavern, staying within the light zone and 40 metres/130 feet total distance from the surface. You learn about cavern navigation and line protocols, planning, swimming techniques, overhead environment hazards, equipment configuration, lighting, guidelines, reels, redundancy, air sharing, silting, air management, and emergency procedures.  Caverns offer some of the worlds most beautiful diving!

Diver Propulsion Vehicle Diver

The Diver Propulsion Vehicle (DPV) Diver course teaches you how to safely explore greater dive site areas with the use a propulsion vehicle.  DPVs can be purchased through Columbus SCUBA, Inc. (CSI) at a very reasonable cost.  CSI will teach the DPV course at no cost when a DPV is purchased.  DPVs are very easy to operate, however, without proper training, a diver can injure themselves or the aquatic environment.  We strongly advise that anyone diving a DPV receive proper training and certification.  Local quarries, rightfully, require a DPV certification when diving their quarry.

Elite Diver

This program has been designed to provide divers with the highest certification in the recreational level before entering the professional diving circle in teaching or in technical diving. Divers completing 5 IANTD Specialties or more may be eligible to apply for the Elite Diver Certification.  This is a fantastic way of sharpening your diving skills while gaining experience in new areas of diving.

Ice Diver

You will complete a minimum of three ice dives for your certification. Dives are typically done as a group working with support personnel, divers, tenders, and safety divers. You are under the ice to learn to control buoyancy, navigate under the ice, and keep in contact with the lead diver and tenders via line pulls.  The ice diving student will learn to plan and organize ice dives, equipment configuration, site selection, preparation, hole-cutting procedures, line handling, safety line operations, and emergency procedures.

Night Diver

The night diving specialty is a favorite of Columbus SCUBA, Inc. (CSI).  We conduct night dives just about every weekend throughout the summer months in Ohio.  A night dive is a dive that occurs without the presence of ambient sunlight.  You will learn night dive planning, light use and selection, night navigation techniques, communications and emergency procedures.  Introduce yourself to the whole new cast of critters that come out after the sun goes down, and see your favorite dive sites from a whole new perspective at night.  This is a course not to be missed.

Nitrox

Our most popular specialty course.  In 1985, Dick Rutkowski brought Nitrox Enriched Air diving into the sport diving world with the International Association of Nitrox Diving (Later IANTD).  Increase your bottom times by reducing the nitrogen content in the gas you breathe by diving Nitrox.  Safe and easy to calculate with either a computer or dive table, Nitrox opens up a whole new world to divers.  Nitrox can be taken in conjunction with Open Water or added as a specialty diver certification.  All CSI instructors hold ratings of EANx (Nitrox Instructor).

Recreational Trimix

IANTD is the only training agency that offers Trimix diving at a recreational level.  Similar to the Nitrox Diver course, the Recreational Trimix course teaches the diver to safely use Trimix (Helium, Nitrogen, and Oxygen blends) for no-stop dives.  Trimix reduces the effects of Inert Gas Narcosis and “takes the edge off” while diving deeper.  The Recreational Trimix Course prepares divers for Advanced Recreational Trimix which incorporates decompression stop and diving to depths of 165 ft.

Rescue Diver

The Rescue course incorporates both fellow diver and self-rescue.  The rescue diver course is an integral step in moving on to dive leadership and more importantly educates divers about being prepared in the event of a diving related emergency.  It incorporates both classroom and in-water training.  Rescue simulations set the scene for a fun and exciting diving weekend.  The rescue course is both challenging and fun.  A must for every diving enthusiast.

Search and Rescue Diver

Find lost items and lift them to the surface. It’s fun to use the lift bag. Not only are these skills fun, but very practical and ultimately useful because it’s quite possible that you or someone else may lose something in the water. As a Search and Recovery Diver, you’ll know how to search for and recover it.  You will learn the techniques necessary to run search patterns, use a lift bag and safely bring objects to the surface.

Wreck Diver

Whether sunk on purpose as an artificial reef or the result of mishap, wrecks open fascinating windows to the past. Most divers find wrecked ships, airplanes and even automobiles nearly irresistible because they’re intriguing to explore, exciting avenues of discovery, and usually teaming with aquatic life. The PADI Wreck Diver course teaches you the ins and outs of rewarding, responsible wreck diving.  Techniques for diving exploring shipwrecks, and how to avoid common hazards include equipment configuration, wreck penetration, guide line use, overhead environment hazards, planning, organizing, gas management and special equipment considerations.
