Choosing dive computers & instruments means balancing the features you want underwater against the format and price you are willing to accept. The Shearwater Research Peregrine Adventures Edition is aimed at scuba and snorkeling enthusiasts who want decompression calculations and dive profiling in a wrist-worn computer, with a listed price of USD 499.99.
Quick verdict
The Peregrine is a sensible fit for divers who want a dedicated wrist computer rather than a basic instrument. Its combination of decompression calculations, dive profiling, and a comfortable wrist-worn design gives it a clear role for scuba use. The main trade-off is the USD 499.99 price, which makes the feature set and wrist format important to your decision.
Shearwater Research Peregrine Adventures Edition Dive Computer

The strongest reason to choose the Shearwater Peregrine is its focus on core dive-computer functions: decompression calculations and dive profiling. The Peregrine model is also explicitly designed for scuba and snorkeling, while its wrist-worn format keeps the computer positioned on the diver rather than as a separate handheld instrument.
The limitation is equally specific: a wrist-worn computer will not suit every diver's preferred equipment arrangement. Someone who wants a different instrument format may find the design less appealing, even though the product's purpose is clear. The package is one unit, so the purchase centers on the computer itself rather than a multi-piece instrument set.
Who it suits
This computer makes the most sense for scuba or snorkeling enthusiasts who want more than a simple depth display. Decompression calculations and dive profiling are useful reasons to focus on a dedicated computer, while the Peregrine name and wrist-worn design make the intended use easy to understand. It also suits shoppers who prefer wearing their dive computer on the wrist during a session.
The USD 499.99 price makes the choice more deliberate. Before buying, decide whether you will use the computer-focused features often enough to justify that amount. If your priority is specifically a wrist computer for decompression calculations and dive profiling, the Peregrine's stated feature set is aligned with that use.
What stands out from the details
The Peregrine combines several relevant functions without drifting into an unclear product role. Decompression calculations address planning-related computer needs, while dive profiling supports reviewing the shape and progress of a dive. The comfortable wrist-worn design adds a practical format choice for users who want the display attached to the wrist.
The model is identified as a Shearwater Peregrine and is described as new, with a unit quantity of one. Those details keep the purchase straightforward: you are choosing a single Peregrine wrist computer, not a bundle of multiple instruments.
Meaningful trade-offs
There are two concrete considerations. First, USD 499.99 is a substantial listed price for a single unit, so the decision depends on wanting the computer functions rather than simply needing a basic underwater instrument. Second, the wrist-worn format is central to the design; divers who prefer another equipment layout may not find that format appealing.
Bottom line
Choose the Shearwater Research Peregrine Adventures Edition if your scuba or snorkeling plans call for a wrist-worn computer with decompression calculations and dive profiling. Its main compromise is the price and the commitment to a wrist-based design. For shoppers whose priorities match those specifics, the Peregrine presents a focused and understandable choice.
