It supports single-gas Nitrox (21–50%), enabling divers to tailor gas mixes for longer or safer profiles. The device relies on the Buhlmann ZH-L16C algorithm with dual gradient factors, delivering decompression data you can depend on for safety. A compact design suits smaller wrists, while the EZ interface emphasizes straightforward operation under water.
Mares Puck Pro EZ Wrist Dive Computer
This second listing presents the same Mares Puck Pro EZ feature set with emphasis on readability and single-gas Nitrox compatibility. The device continues to utilize Buhlmann ZH-L16C calculations with dual gradient factors for decompression assessment, making it a solid option for recreational divers who value clarity and safety in a compact wrist monitor. The Puck Pro EZ’s interface prioritizes quick data access, ensuring critical dive information remains in sight during ascent and safety stops.
SUUNTO Zoop Novo Wrist Scuba Diving Computer
The SUUNTO Zoop Novo focuses on versatile modes suitable for varied diving scenarios. It offers air, nitrox, gauge, and freedom modes with programmable oxygen settings from 21% to 50%. Programmability in both imperial and metric units supports global use. Decompression stop data and audible alarms enhance safety, while the interface is designed for intuitive navigation. For divers who want reliable, easy-to-use decompression planning with clear alarms, the Zoop Novo provides a practical, value-oriented option without overwhelming controls.
SUUNTO Zoop Novo Aqua Blue
Another color variant of the Zoop Novo, the Aqua Blue edition shares the same robust feature set. Divers benefit from multi-mode operation, including air and nitrox, with gauge and freedom options. The device supports 21–50% oxygen mixtures and can switch between imperial or metric units. Audible alarms and decompression stop data help maintain safety during ascent, while the bright display aids readability in bright underwater environments. This variant is ideal for divers seeking a familiar Suunto interface with a distinct color that helps in quick identification on the wrist.
SUUNTO Zoop Novo Lemon Yellow
The Lemon Yellow Zoop Novo presents identical performance to its siblings, with adaptable modes for air, nitrox, gauge, and freedom. Programmable PO2 from 21% to 50% and support for both imperial and metric units ensure international usability. As with other Zoop Novo models, this watch provides decompression stop data and audible alarms for safety. The bright color aids identification, especially in shared rental fleets or busy dive sites, while preserving the familiar Suunto user experience.
Cressi Raffaello Scuba Dive Wrist Computer
The Cressi Raffaello integrates advanced RGBM-based planning with a built-in compass for navigational support. Its durable body and large display focus on readability and long battery life, ensuring essential dive data remains accessible during complex dives. The RGBM algorithm supports safe ascent planning across diverse gas mixes, while safety features include oxygen toxicity indicators and ascent-speed alarms. This model suits divers who want an integrated navigational tool without sacrificing robust decompression data and clear screens.
Cressi Leonardo 2.0 Dive Computer
The Cressi Leonardo 2.0 emphasizes ease of use with a single-button design for navigation and mode selection. It supports Air, Nitrox, and Gauge modes, with adjustable FO2 from 21% to 50% and PO2 from 1.2 to 1.6 bar for tailored safety margins. A CNS oxygen toxicity indicator and audible alarms enhance underwater awareness, and the device includes a backlit display for low-light conditions. The Leonardo 2.0 is well-suited to divers seeking a simple, dependable interface without sacrificing essential safety features.
SCUBAPRO Luna 2.0 AI Wrist Dive Computer
The SCUBAPRO Luna 2.0 AI combines wrist-based diving data with Bluetooth connectivity for wireless logging and updates. Its display is designed for easy readability, and the device uses two-button control for straightforward operation. The AI (air integration) feature streamlines gas management by sharing tank data with the computer, while the device remains compatible with standard gas mixes and decompression data. This model appeals to divers seeking a modern, connected computer with reliable core algorithms and accessible controls.
Buying Guide
Key purchase considerations include display readability, which is critical for quick data recognition underwater. Look for high-contrast screens and backlighting that remains legible in low-light conditions.
Gas options are essential: many wrist computers support Nitrox in the 21–50% range. If you anticipate multi-gas dives or advanced planning, ensure the algorithm (e.g., Buhlmann ZH-L16C or RGBM) is robust and well-documented.
Modes and flexibility matter. Devices typically offer Air, Nitrox, Gauge, and sometimes Freedom modes. Programmable PO2 and FO2 ranges expand safety and customization for individual dive profiles.
Decompression data and alarms are non-negotiables for safety. Audible alarms, decompression stop data, and conservative settings give divers confidence during ascent and safety stops.
Additional features can influence value: built-in compass, Bluetooth or USB connectivity, and long battery life. Some models offer color variants for easier wrist identification, and AI-enabled gas integration can streamline information flow on multi-tank dives.
Brand considerations vary by preference and ecosystem. SUUNTO models are known for user-friendly interfaces and durable builds; Mares and Cressi provide robust options with straightforward controls. SCUBAPRO emphasizes modern connectivity alongside traditional depth and time data. Compare these aspects against your diving goals, whether focusing on recreational nitrox, navigation, or advanced planning capabilities.
