What 5 specialties should I do to get MSD rating?
The question turns out to be thought-provoking to me, as an Instructor, because it can be addressed from at least 3 different perspectives.
The first view, which gcarter thoughtfully addressed, is probably the one most centered on the person asking the question: do five specialties that are of genuine interest to you. Enjoy the journey to MSD, not just the destination.
The second view, which may be seen either as pragmatic or cynical: - do the five that are easiest to complete, most readily available, etc., if the goal is the MSD certification. More than a few divers take that approach (I admit that I did, many years ago). MSD provides a number of divers with a definable goal, a target, something tangible to work toward while enjoying diving. For some, it even provides a basis for 'competition' - my dive buddy at the time and I had a friendly competition going as to who would reach MSD first (we essentially tied).
The third view is more personal, and specific to, the respondent - i.e. from MY perspective as a diver (with the inextricable influence of instructing), what do I see and recommend as the best and
most broadly applicable approaches to enhancing and expanding diver development and skills. These are by no means the only specialties that could be recommended, rather they are my individual preferences: 1)
Enriched Air Diver (which you have) is probably the most generally useful specialty for recreational divers; 2)
Peak Performance Buoyancy is also broadly applicable. A PPB course that helps the diver optimize their weighting, AND optimize their weight distribution and in-water trim, AND develop a more streamlined gear configuration, AND improve their propulsion / finning techniques and their underwater profile, AND enhance their breathing control, is very valuable although time-intensive; 3)
Deep Diver helps a diver expand their diving window, in a structured manner, and better understand how depth affects them and their equipment, and what precautions and techniques are appropriate to allow them to dive to recreational depth limits with relative safety (compared to the diver without the training) and enjoyably; 4)
Night Diver can open up a whole new underwater world, and help a diver develop the confidence to explore and enjoy that world. As a newer diver, I was frankly apprehensive about diving at night, and I was almost paralyzed by a lot of 'what if' scenarios - what if I get separated from my buddy, what if I can't find my way back to the boat, what if I surface and there is no boat in sight, what if I run out of air, etc., etc. For many years I actually avoided diving at night. Now, I love diving at night (and diving solo at night). I just wish I had taken a good, ocean-based Night Diver course early on because it might have helped me develop an enjoyment of, and comfort with, diving at night much sooner; 5) either
Underwater Navigation or
Search and Recovery Diver would be both a useful course, and an enjoyable one. Most new divers that I work with have little / no facility for compass use, on land, in the water. They are either directionally challenged (probably the case with majority), or have never, ever been exposed to a compass. But, in addition, they often have such tunnel vision when diving that the effective use of natural navigation eludes them. Learning to competently navigate underwater enhances diver confidence, and comfort, and makes diving more enjoyable. At the same time, developing skills to search for and recover objects underwater is both quite a lot of fun, and very useful. I saw that just this weekend, when a diver lost half of her weights (you really do need to zip those weight pockets closed) in a local quarry, and was not exactly sure how close she was to the dock when it happened (she was on the surface, swimming in). She was faced with not being able to do a second dive, or having to borrow weights - either of which would still have left her with the loss of some weight. Her dive buddy executed a very effective search pattern and found the weights (four, 1 pound weights, wrapped in duct tape, enclosed in a clear plastic zip lock bag) on a very silty quarry bottom in 25 feet of water.
