It’s no secret freediving has enjoyed a tremendous surge in popularity in just the past few years. Long fins, camouflaged wetsuits and all the other trappings of freediving are showing up everywhere. Unfortunately, most of the people we see using it have no idea what they are doing and, as a consequence, die all too frequently.

Few topics seem to generate more confusion among divers and instructors than Respiratory Minute Volume, better known as RMV, and Surface Air Consumption rate, commonly referred to as SAC rate. This article will tell you what you need to know in simple, easy-to-understand language.

The other day, I got an interesting comment on a photo I posted way back in December. The photo (shown below) is a still-frame capture from a You Tube video.

Lawsuits are something you expect to happen to The Other Guy. Certainly not to you. You’re a good instructor. You teach responsibly and follow standards. Your students love you and would never dream of actually suing you. And, in your fantasy world, peace and harmony abound, and every child gets a pony. Yeah…right.
If you cave dive, it’s almost inevitable that one day, for any of a variety of reasons, you may be forced to leave a reel in the cave that you hadn’t intended to. It’s usually because you were not able to make a subsequent dive during which you planned to retrieve a primary or jump reel you installed on a previous dive. This could be because a team member wasn’t feeling up to it physically, or perhaps an equipment malfunction prevented you from diving. Whatever the reason, it’s important that you not simply leave the reel without telling anyone and have a plan for its removal.
