Is the ballet machine applicable in diving training
In November last 2018, the SNSI training agency (Scuba & Nitrox Safety International) at the DEMA Show in Los Angeles made a sensation in some ways and caused heated discussions among not only professionals, but also diving enthusiasts. All sorts of discussions did not remain within the walls of the exhibition complex, and in accordance with modern trends, they spilled onto social networks with numerous video views and heated debate in different languages.
What was it about? What so surprised? The fact is that SNSI has developed and implemented a completely new, fundamentally different from others method of training in diving. Now, in 2019, when all the new SNSI instructors learn exactly how to conduct classes with their future students, we are pleased to introduce the new method to our readers.
To understand what is at stake, let’s look back a few decades ago and recall what the equipment looked like, in which the then scuba diving enthusiasts went underwater.
The first thing we notice is their lack of buoyancy compensators. To maintain the depth he needed, the diver had to be constantly in motion. It naturally follows from this that the only method that allowed the training of new divers was the following: you had to give your students more loads, put them on their knees opposite you at the bottom of the pool or pond, and in this position to learn and develop the necessary skills. It was quite natural and logical.
However, nothing stands still: the era of buoyancy compensators has come. We don’t have a task to make a historical excursion and talk about all the models and types of BCD that have appeared on the market over the past years, but for some reason, even with the advent of the most modern BCDs, no one thought that training should also be updated, because BCD is needed not only for securing the balloon.
It is widely believed that one of the most valuable skills needed for early development is buoyancy control, and this is precisely what BCD was designed for! SNSI believes that it is high time to begin to use the BC effectively. That is, as equipment that was originally created in the form of a tool that allows you to comfortably enjoy the miracle of diving.
Some time ago, a number of training agencies began to ask their instructors to pay more attention to the environment and to teach students better control of buoyancy from the most elementary courses. However, they did not explain to them how to do this. As a result, some instructors began teaching elementary courses, asking students to remain in neutral buoyancy. But without any help, this leads to a radical decrease in the ratio “Student: Instructor” – a maximum of 2 students per instructor, because the instructor has only 2 hands! But this ratio is unacceptable for diving centers that need to profit from the courses they offer. Long work and repeated experiments led SNSI to the idea of using a training tool that would allow training a group of novice divers in neutral buoyancy from the very beginning, without reducing the Student: Instructor ratio and, most importantly, without reducing the level of student safety.
So, get acquainted: our tool is the SNSI Buoyancy Bar. The SNSI Buoyancy Bar is very similar to the decompression bar, which is sometimes used by experienced divers when diving, requiring mandatory decompression stops. Divers who tried to use such a station know how easy and comfortable it is to stay at the required depth if you have a crossbar that works as a control point, which, if necessary, can be grabbed by hand.
SNSI found a solution for both novice divers, so that they can learn how to manage BCD in a natural setting, and for instructors, so that they can train without reducing the number of students and without reducing the level of control.
However, there is something much more important: if we take a group of 6 students of the Open Water course as an example, we can roughly calculate that before using the SNSI Buoyancy Bar, each student worked with the instructor for a maximum of 10 minutes, while the rest of the time kneeling at the bottom and watching his partners perform exercises. Using the SNSI Buoyancy Bar, all students practice buoyancy control for the duration of the dive, because while they are not doing the exercises, they remain in a neutral position, holding the bar with their right hand and controlling the BCD with their left. So a simple tool is
