Dive Computers & Instruments: How to Choose Between a New Peregrine and Used Teric or Perdix

Choosing dive computers & instruments means weighing price against mode detail, model-specific configuration, and condition. Compare two new Peregrine models with a used Teric and an OG Perdix to find the right fit for your dive plans.

Last updated Aug 26, 2026

Buying dive computers & instruments is not simply a matter of choosing the highest-priced model. The real decision is whether you want a new Peregrine, more explicitly described diving modes, a particular Teric configuration, or a used Perdix with significant wear. The comparison below keeps those trade-offs separate so you can match the computer to your priorities.

Quick take

Start with your non-negotiable: the lowest listed price, named operating modes, a specific model configuration, or tolerance for used gear. The table makes the price spread easy to see; the decision matrix then separates the four buying paths without treating a higher number as an automatic advantage.

Product notes

Shearwater Research Peregrine Adventures Edition Dive Computer

Shearwater Research Peregrine Adventures Edition Dive Computer

Shoppers who want a new Peregrine for scuba or snorkeling have a clear reason to choose this Adventures Edition: its description names decompression calculations, dive profiling, and a wrist-worn design. The Model is Peregrine, and the condition is New. The limitation is package scope: Unit Quantity is 1, so it represents a single-computer purchase rather than a multi-unit set. The Adventures Edition wording also separates it from the standard Peregrine title, making the exact edition an important part of the choice.

Pick the standard Peregrine when operating modes are the deciding detail. The description explicitly names Air, Nitrox, 3 Gas Nitrox, and Gauge modes, along with a full-colour 5.59cm LCD and a simple layout. Its condition is New, and the model title is straightforward for shoppers comparing it with the Adventures Edition. The trade-off is the USD 580.00 listed price, which is $80.01 above the Adventures Edition. That price gap is the concrete reason to compare the two Peregrine titles before choosing.

Teric earns consideration when the named hardware and package contents matter more than choosing a new Peregrine. The title specifies a black 55mm model, and the attributes name a silicone band; the description includes a charger, case, documents, and carabiner. The limitation is condition: it is Used, and Manufacturer Warranty is listed as No. The USD 624.99 price is the highest in this comparison, so the Teric case rests on wanting that specific model and listed configuration rather than treating price alone as a reason to choose it.

Choose the OG Perdix when its older-model identity and no-air-integration setup fit the dive plan. The description identifies it as a Gen 1 computer, reports 54 dives, and says it was used as a backup for tech diving. The limitation is physical condition: the housing is scratched, the screen protector has scratches, and the buckles have only one arm on the male end. It is Used, and the description says the computer is sold without a box. That makes it a distinctly condition-sensitive choice, even though its Perdix name is clear.

Final recommendation by use case

  • For the lowest listed price: Choose the Shearwater Research Peregrine Adventures Edition Dive Computer.
  • For clearly stated diving modes: Choose the Shearwater Research Peregrine Dive Computer.
  • For shoppers specifically seeking a Teric: Choose the Shearwater Teric Dive Computer, while accepting its Used condition and warranty status.
  • For an OG Perdix setup: Choose the Shearwater Perdix Wrist Dive Computer - Black only if its documented wear and no-air-integration design fit your plans.

The strongest starting point for a new purchase is between the two Peregrine entries: the Adventures Edition emphasizes the lower listed price, while the standard Peregrine gives the clearest mode breakdown. The Teric and Perdix make more sense when their named configurations matter enough to outweigh the condition trade-offs.
