Dive Training

Home Dive Training
Humans have relied on fish for sustenance for thousands of years, turning the throwing of a spear into a commercial, sporting and recreational industry. A huge percentage of the world's population still depends on fishing, and a great way to keep fish populations abundant is to fish sustainably. One of the most rewarding ways to do so is to revert to the ways of our ancestors by spearfishing or harvesting by hand.
So here we are at the backdoor of Roger’s air fill station. He carries a lot more here than just his air fill: tanks, scuba gear, and his friends’ gear as well. It gives you an idea of the complexity. Here’s the problem: I mentioned earlier this is an ACFM compressor: you hook up your 80 cubic-foot tank and roughly 10 to 15 minutes later, one tank is full. That won’t work for us. We need four or five tanks filled at once. How do you do that? You obviously hook up more hoses.
By Alec Peirce It took a while before we caught onto the fact that a power inflator valve (PIV) actually saved air, and after that, it became common. All BCs today have the same power inflator...
Flexibility can be highly beneficial or put them into unnecessarily dangerous situations. When the dive plans change to involve an easier site or less challenging conditions, the new diver can take the opportunity to work on skills and improve them. A change to a significantly deeper or higher current site may result in them seeing a test beyond their abilities that causes an accident.To avoid getting into trouble, they should take an honest look at the entire dive and at themselves. Following this, they need to be frank with buddies, shops, guides, and operations, and when called for, insist on a less risky dive. To not do so may pacify others but this activity is not about pacification. It’s about staying safe and staying alive. Flexibility in planning is not going along to get along. It’s about being able to adapt to changes in an intelligent way that does not pose additional risk to the diver or the divers buddies.

Inevitably once a new diver starts to develop some skills and confidence, this is a topic I am often asked. Usually, it comes up when divers start thinking about diving deeper, expanding their group of buddies, traveling, and in some cases because it looks cool. The latter may weirdly make some sense, but it is never a good reason to start diving with new gear.
