Choosing between dive computers & instruments is a practical tradeoff: spend less on a focused computer, or spend more for a package with more specifically named accessories. The useful decision is whether your setup matches the Perdix configuration or the Teric bundle. Here is how the price, configuration, condition, and included gear shape the choice.
Quick verdict
Perdix is the price-first choice; Teric is the package-first choice. The $124.99 absolute spread matters only if Teric's accessories fit your plan. Both units are used, so the price gap is not the whole story: physical condition and the stated configuration remain important. In short, Perdix is the focused lower-outlay route, while Teric is the more specified purchase.
Compact comparison
| Detail | Shearwater Perdix Wrist | Shearwater Teric 55mm |
|---|---|---|
| Price | USD 500.00 | USD 624.99 |
| Configuration | No air integration | Multi-gas decompression |
| Condition | Used | Used |
Where each product wins
Perdix wins when no air integration is the requirement. Its explicit configuration makes it a direct match for a diver who wants that setup rather than an air-integrated computer. The black wrist-computer format and Perdix model name also keep the choice clearly defined.
Teric wins on the specified accessory package. It includes a genuine charger, M/L band, case, documents, and carabiner, giving it a more expansive package than the Perdix computer-only arrangement. That advantage is about included gear, not a claim about dive performance.
Product notes
Shearwater Perdix Wrist Dive Computer
The Shearwater Perdix Wrist Dive Computer suits someone who wants the identified Perdix model in a black wrist format and a computer-only purchase. The limitation is physical condition: the housing has scratches throughout, the screen protector is scratched, and the male buckle end has only one arm. The package is the computer alone, while blue bungees are mentioned as a possible inclusion rather than a confirmed fitted strap system. Those details make the Perdix a deliberate choice for shoppers comfortable with visible wear and the buckle situation. Choose it when the specific configuration and compact package fit your plan. Pass when the condition issues or need for a charger and case would outweigh the lower purchase price.
Shearwater Teric Dive Computer Black 55mm
The Shearwater Teric Dive Computer Black 55mm suits shoppers who care about its silicone band and Android compatibility. Those are concrete attributes to match against your own gear and device setup. The case is specified at 55mm, making physical fit an important part of the decision rather than a performance claim. The unit is also marked used. Multi-gas decompression is part of its stated configuration, but that should be treated as a feature to match to your needs, not proof that Teric is universally superior. Choose Teric when the band, operating-system compatibility, and case size all make sense for your equipment. If 55mm is not the size you want, that configuration is a decisive limitation.
Final choice by use case
- Choose Shearwater Perdix when the described housing scratches and broken buckle are acceptable and its specific configuration matches your plan.
- Choose Shearwater Teric when the silicone band, Android compatibility, and included charger, case, documents, M/L band, and carabiner are worth prioritizing.
- If price is the deciding factor, Perdix is the lower-priced pick. If included gear is the deciding factor, Teric has the more fully specified package.
The cleanest decision is condition first, then configuration, then accessories: Perdix for the focused purchase, Teric for the defined bundle.
