Diving Essentials
Scuba diving is swimming underwater, or taking part in another activity, while using a scuba set. By carrying a source of breathing gas (usually compressed air), the scuba diver is able to stay underwater longer than with the simple breath-holding techniques used in snorkeling and free-diving, and is not hindered by air lines to a remote air source.

Ankl Weights™
A diver’s gear (wet suit, fins, B.C., tank, weights and regulator) can weigh anywhere from 40 to 70 pounds. The bulk of this weight is in the middle of your body – while over half of your buoyancy is below the waist. Reduce leg and fin buoyancy and alleviate back stress by wearing Durward Ankl Weights™.

Proper Knife Usage
Knives are essential tools for every diver. Use your knife to cut away from entanglements, to examine under rocks, and to bang on your tank to get your buddy’s attention. Mount knife on your B.C. vest or leg for easy access.

Split Fins
Modeled after a whale’s tail, split fins funnel the water delivering more forward motion with considerably less effort than traditional blade-style fins. The twin blades act like counter-rotating propellers, reducing drag and turbulence, allowing for easier underwater maneuvering. Many divers also report that, after switching from blade to split-fins, they no longer experience calf muscle cramps.
