Choosing dive computers & instruments starts with a practical tension: a simple interface may be easier to navigate, while technical-dive features can add control you may or may not use. The four choices also split between new and used condition and sit across a wide price range. Sort the decision by dive scope, model phrase, condition, and then price to find the closest match.
Quick take
The two Peregrine choices share a model family, while the Teric brings a distinct 55mm format and used condition. The Deep 6 Excursion is explicitly framed for recreational and technical diving. No single computer fits every diver, so decide first whether model identity, straightforward operation, technical scope, or condition matters most.

Decision matrix
| Decision point | How the choices divide |
|---|---|
| Model phrase | Peregrine Adventures Edition; Peregrine; Teric; or Excursion |
| Condition | Peregrine Adventures Edition, Peregrine, and Excursion are new; Teric is used |
| Price order | Excursion is lowest, followed by Adventures Edition, Peregrine, and Teric |
| First filter | Use the Peregrine family for its model identity, Teric for its named format, or Excursion for its recreational-and-technical wording |
Shearwater Research Peregrine Adventures Edition Dive Computer

The Shearwater Research Peregrine Adventures Edition Dive Computer suits a shopper who wants a new Peregrine with a wrist-worn design, decompression calculations, and dive profiling. The Adventures Edition phrase also makes the model easy to distinguish from the standard Peregrine. At USD 499.99, it is USD 300.99 above Deep 6 Excursion, so the price spread is a real limitation for a shopper prioritizing the lowest outlay. The single-unit quantity keeps the purchase scope clear. Choose the Adventures Edition when the Peregrine format and wrist use matter more than technical-dive breadth or the lowest price.
Shearwater Research Peregrine Dive Computer

Shearwater Research Peregrine Dive Computer is the clearest fit for a shopper prioritizing a simple interface with an explicitly defined mode set. Air, Nitrox, 3 Gas Nitrox, and Gauge modes are named, along with a full-colour 5.59 cm LCD and easy navigation. That combination gives the model a concrete reason to choose it for divers who want the screen and operating modes spelled out. At USD 580.00, it is USD 80.01 above the Adventures Edition and USD 381 above Deep 6 Excursion. The limitation is price: the standard Peregrine sits above the Adventures Edition despite the shared Peregrine family. Pick it when the stated display and modes justify the difference.
Shearwater Teric Dive Computer Black 55mm

The Shearwater Teric Dive Computer Black 55mm suits shoppers who specifically want the Teric model, a 55mm case, a silicone band, and multi-gas decompression capability. Android is named as a compatible operating system, giving that detail a clear place in the decision. The main limitation is condition: Teric is identified as used, while the other three are new. It also carries the highest listed price at USD 624.99, so the combination of used condition and highest price deserves deliberate consideration. Choose Teric when the 55mm format and multi-gas decompression package matter more than new condition or the lower prices elsewhere.
Deep 6 Excursion Scuba Dive Computer for Recreational and Technical Diving New

Deep 6 Excursion Scuba Dive Computer for Recreational and Technical Diving New is the price-led choice, and its feature list names gas and decompression settings in detail. Multi-Gas Nitrox covers 20%-99% and four gases; Helitrox is supported up to 22% helium; scuba, planning, apnea/free-diving, and Gauge modes are also included. Bluetooth supports logging and updates, while variable-brightness backlighting and fast-charging mode add practical controls. The limitation is breadth: user-settable gradient factors, safety factors, a tissue graph, and residual-nitrogen reset may be more than someone seeking a simple recreational setup wants. Choose Excursion when technical scope matters.
Final recommendation by use case
- Adventures Edition wording: Choose Shearwater Research Peregrine Adventures Edition Dive Computer when that exact title phrase and Peregrine format are the priority.
- Straightforward Peregrine choice: Choose Shearwater Research Peregrine Dive Computer when the standard Peregrine model identity is the deciding factor.
- Recreational-and-technical scope: Choose Deep 6 Excursion Scuba Dive Computer for Recreational and Technical Diving New when that exact use case is central. It sits at the low end of the USD 425.99 listed-price spread.
- Teric model: Choose Shearwater Teric Dive Computer Black 55mm when the Teric name and 55mm format outweigh the used condition and highest listed price.
For most shoppers, model and dive scope should come first; condition and price then resolve the close calls.
