Shearwater Peregrine Dive Computer
The Peregrine combines essential diving metrics with a compact form. Its two-button interface enables straightforward navigation, supported by a state-aware menu structure that helps divers quickly access depth, time, and decompression data. The device uses robust 316 stainless steel buttons for durability in wet environments. Battery life reaches up to about 30 hours on a medium brightness level, which is adequate for most recreational and some extended dives, depending on display settings and gas planning. This model targets divers who want dependable performance in a streamlined package.
Shearwater Perdix 2 Ti Dive Computer (Silver + Swift Combo)
The Perdix 2 Ti is designed for divers who demand high visibility and extended dive capability. It features a vibrant 2.2″ LCD with LED backlight and 320×240 resolution to ensure readability in challenging underwater lighting. Battery options include up to 100 hours with a Saft LS14500, up to 60 hours with Lithium 1.5V, or up to 40 hours on standard AA Alkaline batteries. This model also supports versatile gas switching with up to five Open Circuit and five Closed Circuit gases, enabling safe transitions on complex dive profiles.
Mares Puck Pro EZ Wrist Dive Computer
The Mares Puck Pro EZ emphasizes visibility and reliable decompression logic. Its clear, high-contrast screen keeps depth, time, temperature, and no-deco limits legible at a glance. It supports single-gas Nitrox (21-50%), making it suitable for recreational divers seeking enriched air. The Puck Pro EZ employs the Buhlmann ZH-L16C algorithm with dual gradient factors, delivering precise decompression calculations. The combination of an intuitive interface and robust algorithm appeals to divers who value dependable dive data in a compact wrist unit.
Shearwater Perdix 2 Ti Dive Computer (Titanium)
Built from resilient titanium, this Perdix 2 Ti emphasizes durability in demanding conditions. It pairs a brilliant 2.2″ display with strong readability in varied lighting. An optional air integration feature allows for real-time gas monitoring, which is valuable for divers who need to track tank pressures alongside depth and time. The titanium build adds weight and rigidity that many technical divers appreciate for extended missions and rough environments. The combination of rugged build and flexible gas options makes it a strong choice for demanding dives.
SUUNTO D5 Dive Computer
The SUUNTO D5 emphasizes daily wearability with a color display and interchangeable straps, blending dive functionality with fashion-friendly design. It offers 100 meters of water resistance, wireless tank pressure, and vibration alarms to alert divers to critical information. While its feature set centers on user-friendly operation and smart notifications, it remains a capable recreational tool, especially for divers who appreciate quick access to tank data and dive status without sacrificing style or comfort.
Buying Guide
- Display readability: Look for high-contrast screens and adjustable brightness to ensure data is legible in low-light conditions or during ascent.
- Battery flexibility: Consider models with multiple battery options or long-life cells for extended expeditions or remote locations.
- Gas switching and algorithm: Decide between Open Circuit and Closed Circuit support, and review the decompression model (e.g., ZH-L16C) to match your training level and dive profiles.
- Durability and materials: Titanium or stainless-steel housings can withstand harsher environments, while weight considerations matter for travel and buoyancy.
- User interface: Two-button or multi-button navigation affects learning curve. A state-aware menu structure can simplify access to critical data during dives.
- Air integration: For divers who monitor tank pressure continuously, consider a model with hoseless or wireless air integration and transmitter compatibility.
- Connectivity and app ecosystem: Some models sync with smartphone apps for pre-dive planning and dive log management; assess whether DiverLog+, Subsurface, or similar tools suit your workflow.
- Intended use: Recreational, technical (Tec), or blended diving needs will guide the balance between display features, gas options, and data complexity.
- Upgrade path: Brands offering modular or titanium builds may better serve divers planning to extend into more demanding dive profiles.
This selection provides a spectrum of features from bright displays and long-battery options to rugged construction and advanced gas management. When choosing, align the device with your typical dive depth, gas strategy, and how you prefer to view dive data. Always verify compatibility with your preferred gas mixtures and whether air integration is essential for your workflow.
