Shearwater Research Petrel 2 SA Dive Computer

[amazon box=”B00S1U9S7M”]

This model doesn’t take the form of a wristwatch and is instead a significantly bulkier, no-nonsense block that straps onto the forearm. Although it isn’t necessarily an attractive model, visually, it offers a wide number of extremely specified and technical features, making it perfect for the pro looking to get the most detailed reports possible on their dives. The unit features four main modes, OC Rec for a 3 gas recreational computer, OC Tec for a multi-gas decompression computer, CC INT for a closed circuit fixed PPO2, and Gauge for a bottom timer with a stopwatch and dive logging.

Although this model is bulky, its increased size allows for even more information to be displayed on its screen. However, it’s hardly something you could wear around comfortably on land.

Pros

  • A wide variety of modes and potential statistical readouts

Conclusion

When looking at dive computers, more features isn’t always best.
