If you are an open circuit diver, it is becoming increasingly common to find yourself on a boat with a rebreather diver; or perhaps you may even get assigned a
rebreather diver as a buddy. Like you, the rebreather diver has been trained to do a few minutes of setup and ...
Using the metal grommets, the DGX sleeve can easily be attached to the bottom or sides of any standard metal backplate using assembly screws or attached to the Transpac using medium quick links or the pear shaped quick links. We find that for this application, the plastic assembly screws work ...
The red-and-white U.S. dive flag was invented in the early 1950's by Denzel James "Doc" Dockery. In 1953, he followed instructions published in Popular Science Magazine for building his own scuba device, and began experimenting with ways to make a living by working in the emerging sport. In ...
Frameless vs. Frame:The lenses in frameless designs will sit closer to your eyes offering a little wider field of vision in all directions. Frameless designs are also typically lower volume than rigid frame designs. The lack of a thick rigid frame means frameless styles can be folded up very ...
A common misconception among divers is that stainless steel does not corrode at all. There are various types of stainless steel, each with different corrosion properties, that make a specific grade more or less suited to a particular application. Because there is no perfect stainless steel, ...
A typical sport diving breathing gas setup consists of a pressurized gas cylinder (aka 'tank') and valve with either a 'Yoke' or 'DIN' outlet. The yoke valve outlet is by far more common in the US and Caribbean but much of the rest of the world uses the DIN valve outlet. Experienced divers ...
The skills required to deploy a finger spool are different than those required to use a typical reel. At first glance the simple spool looks easier, but compared to reels the finger spool requires different specific techniques for successful use. If this is your first finger spool then seek ...
The makers of dive reels and finger spools find themselves "between a rock and a hard place" as they say in cave country. Manufacturers know that for their devices to work properly, the line should only fill about 80% of the spool. Like a cup of liquid filled to the very brim, invariably an ...
We usually hear this from divers who have always worn a jacket style BC, and we'd like to point out that it's irrelevant. It's true, the US Coast Guard requires an approved wearable Personal Floatation Device (PFD) to float the unconscious victim face up in the water. But a Buoyancy ...
The internal structure of the fixed port design allows for a very direct gas flow through the first stage, providing optimal performance. The fixed port design is also typically the most compact as well as being lower cost when compared to a similar swivel turret design. The most common ...
