Buying Guide for the Best Shearwater Dive Computers
Choosing the right dive computer is crucial for ensuring your safety and enhancing your diving experience. Shearwater dive computers are known for their reliability, advanced features, and user-friendly interfaces. When selecting a dive computer, it's important to consider your diving style, experience level, and the specific features that will best support your underwater adventures. Here are some key specifications to consider when choosing a Shearwater dive computer.Display TypeThe display type of a dive computer determines how information is presented to you underwater. This can range from simple monochrome screens to high-resolution color displays. A clear, easy-to-read display is important for quickly accessing critical information during a dive. If you have difficulty reading small text or prefer a more vibrant interface, a color display might be the best choice. For those who prefer simplicity and longer battery life, a monochrome display could be more suitable.
Battery LifeBattery life is a crucial factor, especially for longer dives or multi-day diving trips. Dive computers can have rechargeable batteries or user-replaceable batteries. Rechargeable batteries are convenient and environmentally friendly, but you need to ensure they are fully charged before each dive. User-replaceable batteries offer the flexibility to change them on the go, which can be handy in remote locations. Consider how often you dive and the availability of charging options when choosing the right battery type for you.
AlgorithmThe algorithm used by a dive computer calculates your decompression status and no-decompression limits. Different algorithms can be more or less conservative, affecting how much bottom time you have and how long your surface intervals need to be. If you are a recreational diver, a more conservative algorithm might be preferable for added safety. Technical divers might prefer a more liberal algorithm to maximize bottom time. Understanding your diving habits and risk tolerance will help you choose the right algorithm.
ConnectivityConnectivity features, such as Bluetooth or USB, allow you to download dive logs, update firmware, and connect with other devices. This can be useful for tracking your diving history, sharing data with dive buddies, or analyzing your dives in detail. If you enjoy keeping detailed records or using dive planning software, a dive computer with robust connectivity options will be beneficial. For those who prefer to keep things simple, basic connectivity might suffice.
Durability and Build QualityDurability and build quality are important for ensuring your dive computer can withstand the harsh underwater environment. Look for features like a rugged casing, scratch-resistant screen, and water resistance rating. If you frequently dive in challenging conditions or travel often, a more durable model will provide peace of mind and longevity. Casual divers might not need the highest level of durability, but it's still important to choose a well-built device.
User InterfaceThe user interface of a dive computer affects how easily you can navigate menus and access information. Some models have touchscreens, while others use buttons. A touchscreen can be more intuitive and quicker to use, but may be less responsive with gloves or in cold water. Button-operated interfaces are generally more reliable in all conditions. Consider your typical diving environment and personal preference when choosing the user interface that will be most comfortable for you.
Gas CompatibilityGas compatibility refers to the types of breathing gases the dive computer can handle, such as air, nitrox, trimix, or even rebreather systems. If you are a recreational diver, a computer that supports air and nitrox might be sufficient. Technical divers who use mixed gases or rebreathers will need a model that can handle these advanced requirements. Think about your current and future diving plans to ensure your dive computer can accommodate your needs.
