The Peregrine from Shearwater Research of Canada is an Advanced Nitrox dive computer with easy-to-understand menus. The Peregrine offers a large { 2.2 in | 5.6 cm } easy-to-read display utilizing a COLOR screen. The Peregrine includes open-circuit dive modes for Air, single gas Nitrox (up to 40%), and user selectable 3-gas Advanced Nitrox (up to 100% O2), as well as a richly featured gauge mode. The Shearwater quality, color display and extended range feature set make the Peregrine price an exceptional value.

The Peregrine has been designed with a wireless rechargeable battery and includes a wireless induction charging pad. Typical dive time on a single charge is 30 hours at medium screen brightness. Although Shearwater recommends using their charging pad, the Peregrine can also be charged by the flat mats that support the Qi wireless-charging standard (which includes the latest iPhones and many Android phones).

What's in the box: Included with every Peregrine from Dive Gear Express are a 27 mm black silicone two piece wrist strap kit with installation/removal screwdriver tools, shock cord for bungee mount, zippered ballistic nylon polymer travel case, wireless charging pad and USB cable. The Peregrine also includes a PET screen protector already installed on the screen (plus a spare) to help prevent scratches of the display face. This package also includes a northern hemisphere tech compass, and a "brass & glass" quality SPG in PSI units with a 32" high pressure hose. all integrated in to their console boot including a nylon lanyard with QD side release buckle. The software includes a complete dive log manager, compatible with both MS Windows and MAC OS X, and can be downloaded from Shearwater's website along with the manual. The dive log manager supports log downloads and firmware updates via the Bluetooth wireless interface.

Advanced Nitrox Mode Features

The Peregrine has a 3-gas advanced mode that includes a complete planned decompression feature set for extended range diving. During a decompression dive, the Peregrine provides complete information displays of all required stop times. It supports a user configurable Gradient Factor and "look ahead gas" switching (based on the gases defined and active) for the planner and time-to-surface calculations. The Peregrine will NOT "lockout" after a missed stop or ascent rate violation. The Peregrine also supports 100% oxygen for accelerated decompression with a user configurable deco PO2 setting. The last stop depth is user selectable as {10 fsw | 3 msw } or {20 fsw | 6 msw }. Warnings include prompts to switch gases upon reaching a user configurable optimal PO2 setting and a stop approach notice plus an ascent rate indicator. The real-time multi-compartment "tissue" saturation bar graph does not time out and thus allowing tissue off-gassing to be observed on an extended deco stop without having to cycle back to it repeatedly. For table divers needing a bottom timer, the Peregrine also offers a very richly featured gauge mode operational to at least { 395 fsw | 120 msw }.

Sport Nitrox Mode Features

Sport divers who don't need extended range features will find the Peregrine even more diver friendly! Key features of the Peregrine single gas Sport Nitrox mode include a simpler menu structure, less cluttered display and configurable bottom row, optional safety stops, and a no decompression limit (NDL) dive planner. The simplified settings allow for one breathing gas mixture (Air or Nitrox up to 40%) and places a greater emphasis on the maximum operating depth (MOD) and no decompression time limit. The display prominently warns the diver if their depth is near, at or exceeds the MOD of the selected breathing gas. Optional safety stops are user configurable to be 3, 4, 5 minutes or adaptable. When using the Adapt setting, a 3 minute safety stop will be used, unless the dive exceeds { 100ft | 30m } or the NDL falls below 5 minutes, in which case a 5 minute safety stop is used. If the diver exceeds the NDL and requires stops, the display turns red and warns "DECO STOP" with the mandatory depth and stop times.
