Do I really need a dive computer?
You can track your dives using dive tables, a depth gauge and dive watch, but most scuba divers use a dive computer – it’s easier. A dive computer provides the real-time dive information you need to dive well. Today, with dive computers being the norm, divers wear watches as symbols that identify them as scuba divers. A dive watch looks good, tells you what time of day it is, and can serve as a backup dive timer. You can choose a dive watch that is also a dive computer to get both in one unit.Divers’ watches are designed for the best readability under water possible. This enhances the readability overwater, too. Especially under poor light conditions diver watches are unmatched.Generally, dive watches—including analog or digital—can still be worn by divers, though now they tend to be more of a fashion piece and a backup timekeeping device more than anything else. Many popular watch brands have a diver’s model that consumers may buy for looks.A diving watch, also commonly referred to as a diver’s or dive watch, is a watch designed for underwater diving that features, as a minimum, a water resistance greater than 1. MPa (11 atm), the equivalent of 100 m (330 ft).
Is Apple Watch a dive computer?
Apple Watch Series 10 and Apple Watch Ultra models can track the water temperature, time, and depth during underwater activities such as snorkeling, underwater pool swims, and shallow free-diving. WARNING: Underwater activities are risky. Apple Watch Series 2 and later can be used for shallow-water activities, such as swimming in a pool or ocean, but you shouldn’t use models other than Apple Watch Ultra or later for diving, water skiing or other activities involving submersion below shallow depth or high-velocity water.Apple Watch Series 10 and Apple Watch Ultra models can track the water temperature, time, and depth during underwater activities such as snorkeling, underwater pool swims, and shallow free-diving.Common Characteristics of Dive-Styled Watches Water Resistance. Dive watches are engineered for heavy water activity, so it is important that these watches can withstand larger depths of water resistance. Most dive watches have a depth rating of at least 100 meters, while the average water resistance is 300 meters.
What if my dive computer fails during a dive?
We should note since your dive computer is a required piece of equipment (no different than your mask and fins), it’s important to understand if it fails; the dive is over, period. No questions asked. Calmly signal to your buddy or team, “end the dive” by giving the “thumbs up” hand signal. The Rules of Scuba Diving: Never Hold Your Breath. Plan Your Dive. Dive Within Your Limits.
Why do dive watches go so deep?
Diving watches have relatively thick watch crystals. Sometimes domed crystals are used to enhance the pressure-resistance of the watch and to improve the watch face legibility under water. They are typically made from high-quality materials such as stainless steel or titanium, which are known for their durability and corrosion resistance. This means that a dive watch can handle the wear and tear of everyday use, whether you’re wearing it to the office, the gym, or on outdoor adventures.Most dive watches have a depth rating of 200m (a bit over 600 feet). That covers just about everybody except for a handful of the most elite divers in the world. If you’re looking at a watch that can handle 200m, you’re holding a watch that will be more than adequate for a dive.Even if you have a dive watch that is equipped with a helium valve and screw down crown with a depth rating of 1,000m/3,300ft water resistance, it’s a good idea to take it off your wrist when taking a shower.
