Choosing dive computers & instruments comes down to a practical trade-off: do you need wireless tank-pressure information, a no-air-integration backup, a specific Teric configuration, or a more complete transmitter bundle? These four used options are not interchangeable. Start with the package and dive functions you actually want, then weigh the condition details against the listed price.
Quick take
- Suunto EON Core Wrist Dive Computer - White with Transmitter And USB is the lowest-price route and includes transmitter-related equipment in its name.
- Shearwater Perdix Wrist Dive Computer - Black - Original OG, NO AI fits a buyer seeking the original Perdix configuration without air integration.
- Shearwater Teric Dive Computer Black 55mm is the defined Teric setup with a 55mm case and named charger and case.
- Shearwater Teric Dive Computer w/ Air Integration Transmitter, Charger is the Teric bundle for shoppers who specifically want a transmitter and wireless charging equipment together.
The key split is whether air-related gear is central to the dive plan or whether a simpler computer setup is enough. P1 also has more specific wear and hardware concerns than the other choices, so condition deserves extra attention there.
Listed-price comparison

| Shearwater Perdix Wrist Dive Computer - Black - Original OG, NO AI | USD 500.00 | |
| Shearwater Teric Dive Computer Black 55mm | USD 624.99 | |

Decision matrix
- Air integration: The Suunto configuration names a transmitter and wireless tank pressure. The higher-priced Teric configuration explicitly names an air-integration transmitter, while the original Perdix is identified as having no air integration. The 55mm Teric is centered on the computer, band, charger, case and documents.
- Display and navigation: Suunto specifies a color display with large digits and a digital compass. The transmitter-equipped Teric specifies a full-color AMOLED display and digital compass. Those are the clearest display and compass distinctions in this group.
- Tech-oriented functions: The 55mm Teric includes multi-gas decompression, while the bundled Teric names Air, Nitrox, Trimix, Tech, CCR and Freediving modes. The Perdix description places it in a backup tech-diving context.
- Condition tolerance: All four computers are marked used. The Perdix has the most specific physical caveats: housing scratches, a scratched screen protector and a broken buckle arm.
Product notes
Shearwater Perdix Wrist Dive Computer - Black - Original OG, NO AI
Shearwater Perdix Wrist Dive Computer - Black - Original OG, NO AI is the focused choice for someone seeking that original Perdix configuration for backup tech diving. The setup is explicitly without air integration, so it is easy to separate from transmitter-equipped choices. The limitation is physical condition and package scope: it is used, the housing has scratches, the screen protector is scratched, one male buckle end has a broken arm, and the computer is described without a box. At $500, it sits above the lowest-priced choice. Pick it when the original Perdix format matters more than a ready-made accessory bundle.
Shearwater Teric Dive Computer Black 55mm
Shearwater Teric Dive Computer Black 55mm suits a shopper who wants a defined Teric configuration rather than the original Perdix format. Its 55mm case, silicone band, multi-gas decompression function, charger, case, documents and carabiner give the package a clear shape. The limitation is accessory scope: the description says items are included only when listed and specifically cautions that power cables or other accessories may not be included. It is also marked used. Choose it when the 55mm Teric and included charger and case align with the dive computer you want, without making a transmitter the central reason for the purchase.
Suunto EON Core Wrist Dive Computer - White with Transmitter And USB
Suunto EON Core Wrist Dive Computer - White with Transmitter And USB is the price-led pick when the package needs to name both a transmitter and USB. Its description adds a color display with large digits, wireless tank pressure, digital compass, wireless mobile connection, rechargeable battery, updatable software and customizable settings. That combination suits a diver who prioritizes readable information and compass access alongside tank-pressure data. Its concrete limitation is condition: it is used. The package centers on the computer, transmitter and USB, making it a different accessory proposition from the Teric configuration with a wireless charging station and case. The listed configuration is white.
Shearwater Teric Dive Computer w/ Air Integration Transmitter, Charger
Shearwater Teric Dive Computer w/ Air Integration Transmitter, Charger is for the buyer who wants the Teric name with air-integration hardware explicitly bundled. The package also names a wireless charging station, black/blue zippered case, full-color AMOLED display, sapphire crystal, digital compass, Bluetooth, rechargeable battery, audible and vibration alerts, and a 200 m / 660 ft depth rating. Its mode list includes Air, Nitrox, Trimix, Tech, CCR and Freediving. The limitation is straightforward: at $899.99, it is the highest-priced choice, and it is marked used. Choose it when the transmitter, charging station and mode list justify moving beyond the simpler Teric configuration.
Final recommendation by use case
- Lowest listed-price route: Suunto EON Core Wrist Dive Computer - White with Transmitter And USB.
- Original backup computer without air integration: Shearwater Perdix Wrist Dive Computer - Black - Original OG, NO AI.
- Defined 55mm Teric setup: Shearwater Teric Dive Computer Black 55mm.
- Teric bundle with air-integration equipment: Shearwater Teric Dive Computer w/ Air Integration Transmitter, Charger.
The price range makes bundled equipment a deliberate decision rather than an incidental extra. Match the Suunto or bundled Teric to a transmitter-focused plan, choose the Perdix for its original no-AI configuration, and use the 55mm Teric when that specific computer setup is the priority.
