We all love a deal. And in the world of scuba diving, where a full kit can cost upwards of $3,000, the used market is tempting. But as a technician who sees the “insides” of gear every day, I can tell you that not all bargains are created equal. Is it safe to buy used…
Managing gear for 30 divers and 40+ regulators is logistical chaos. When you send that gear to a standard retail shop, it’s often handled by multiple technicians, each with their own “feel” for how a regulator should breathe. The Danger of “Personal Preference” Inconsistent tuning creates a dangerous fleet. When Regulator A breathes hard and…
“What is the best regulator on the market?” “Which BCD should I buy?” As an SSI Instructor Certifier and NAUI Technical Instructor and someone who has certified thousands of divers, these are the most common questions I hear. They are good questions, but they are incomplete. Online reviews and “Top 10” lists are useful, but…
We are all taught to rinse our BCDs after every dive. And while that helps, fresh water can’t dissolve everything. If you dive in saltwater, microscopic salt crystals eventually find their way inside your power inflator mechanism. As the water evaporates, these crystals harden into something resembling concrete. The “Sticky Button” Scenario One day, you…
“I haven’t serviced my reg in three years, but it breathes fine.” As a technician, I hear this constantly. It’s the scuba equivalent of saying, “I haven’t changed the oil in my truck in 30,000 miles, but the engine still turns over.” While technically true, you are operating on borrowed time. The reality is that…
When Reliability is a Requirement: The Public Safety & Scientific Standard For most, scuba diving is a hobby. For Public Safety Divers (PSD) and Scientific Research teams, it is a high-risk job performed in environments that would terrify the average recreational diver. Whether it’s a black-water recovery in a zero-visibility lake, a search in contaminated…
We love the DIY spirit. But when it comes to dive computers, changing your own battery is often a false economy. Yes, you can buy a battery kit online. You can even unscrew the back yourself. But there is one thing you cannot do on your kitchen table: Verify the seal under pressure. The O-Ring…
One of the most frequent questions I hear in the shop is: “How often should I really get my equipment serviced?” Many divers operate on the philosophy of “If it ain’t broke, don’t fix it.” In the world of life-support equipment, that philosophy is not only dangerous—it is expensive. To understand the answer, we need…
