Mares Puck Lite Scuba Diving Computer | Watch-Style One

Product Overview

The Mares Puck Lite Scuba Diving Computer is a compact, watch-style dive computer designed for both recreational and technical divers who value simplicity, reliability, and advanced functionality. Built for underwater use in freediving and scuba diving environments, it features a single-button control system that streamlines navigation—ideal for gloved hands and low-visibility conditions. With support for Nitrox mixtures and decompression planning powered by the Bühlmann ZH-L16C algorithm, it offers precision and adaptability across a range of dive profiles. Its durable black design and long-lasting battery make it a dependable companion for frequent divers seeking performance without complexity.

Key Features

• Advanced Bühlmann ZH-L16C Algorithm – Utilizes a scientifically validated decompression model that supports customizable gradient factors, enhancing safety during ascent and decompression stops. This allows divers to fine-tune settings based on personal preference, dive conditions, and experience level, making it suitable for both recreational and technical applications.
• Nitrox Compatibility (21% to 50% EAN) – Supports enriched air nitrox mixtures from 21% to 50%, giving divers greater flexibility in gas planning. This enables extended bottom times and reduced surface intervals, ideal for divers looking to maximize efficiency and safety on repetitive dives.
• User-Friendly Single-Button Navigation – Features an intuitive one-button interface that simplifies menu access and mode switching, even when wearing thick gloves. The streamlined design reduces the learning curve and minimizes distractions during critical dive phases.
• High-Visibility Segment Display – Equipped with an 800-segment crystal-clear display using chip-on-glass technology, ensuring sharp, readable information in all underwater lighting conditions. The monochrome screen delivers essential data at a glance without unnecessary complexity.
• Comprehensive Dive Logging – Stores up to 100 hours of dive time with detailed profiles, including depth, time, and decompression data. Dive logs can be reviewed on-device or synced via Bluetooth to the Mares and SSI apps for in-depth analysis, planning, and sharing.
• Long-Lasting User-Replaceable Battery – Powered by a standard CR2450 battery that supports up to 100 hours of dive time, eliminating the need for frequent replacements. The user-replaceable design ensures continued use without requiring professional servicing.
• Bluetooth Connectivity – Integrated Bluetooth allows seamless wireless connection to smartphones and tablets for firmware updates, logbook transfers, and integration with dive planning apps. This ensures the device stays current and data remains accessible across platforms.

Benefits & Use Cases

The Mares Puck Lite is ideal for divers who prioritize simplicity without sacrificing core functionality. Its single-button operation makes it especially well-suited for cold-water diving or situations where dexterity is limited. The Bühlmann algorithm and Nitrox support allow advanced recreational divers to safely plan multi-level and repetitive dives. With 100 hours of log memory, it’s a solid choice for liveaboard trips or extended diving vacations where tracking dive history is essential. The Bluetooth sync capability enables easy integration into digital dive logs, supporting divers who use apps for planning and certification tracking. While not designed for trimix or gas switching, it excels in air and Nitrox environments up to 150 meters, making it a versatile tool for both beginner and experienced divers.

Important Notes

The Mares Puck Lite does not support trimix gas mixtures or gas switching between multiple tanks. The stopwatch function is not available, and profile sampling rate data is not provided. Always ensure the battery compartment is properly sealed before diving. Firmware updates should be performed via Bluetooth using a compatible device and the official Mares app. The device is rated for depths up to 150 meters; exceeding this limit may result in inaccurate readings or damage.
