This computer uses the established Mares-Wienke RGBM algorithm and offers a pre-dive planning function. It supports Nitrox from 21% to 99% and features a logbook that stores dive profiles with a 5-second data sampling rate, providing the detailed information this diver needs to analyze and plan their dives.

Competitive features

When selecting a dive computer, divers often weigh simplicity and core functionality against advanced features and specialized capabilities. The Mares Puck Lite stands out in a competitive field by focusing on user-friendly design and essential features for a broad range of divers. It offers a balance of performance and accessibility, positioning it against models like the Cressi Leonardo and Donatello, which are known for their reliability, and more specialized computers like the Seac Partner, which is geared towards spearfishing.

Consider alternatives if...

Divers who prioritize specialized activities like spearfishing or freediving might find that alternatives such as the Seac Partner Spearfishing Computer or the North Edge Aqua Freedive computer offer more tailored features for those specific pursuits. For divers seeking more advanced functionalities, connectivity options, or a multi-sport design, other models in the market may be a better fit, as the Puck Lite focuses on delivering core diving essentials with streamlined operation.

The Mares Puck Lite Dive Computer is a strong contender for divers who value simplicity, reliability, and ease of use. Its intuitive single-button interface, clear display, and essential safety features like Nitrox compatibility make it an excellent underwater companion.
