Choosing dive computers & instruments comes down to one practical question: do you need wireless tank pressure and a compass, a no-air-integration wrist computer, a specific case configuration, or a lower listed price with more accessories? The four choices here take noticeably different paths, so matching the feature set to your diving setup matters more than simply choosing the most expensive model.
The listed prices span $250.00 to $624.99, a $374.99 spread. Use the feature comparison first, then decide whether the package condition and included accessories fit your priorities.
Quick take
- For wireless tank pressure and a compass: Suunto Eon Core, with a transmitter, wireless pressure data, and a digital compass.
- For a no-AI configuration: Shearwater Perdix, explicitly identified as the original OG model without air integration.
- For multi-gas decompression: Shearwater Teric, with that function named in its description.
- For a lower listed price and kit-oriented purchase: Oceanic Atom 3.1, titled as a full kit with a short 4-5-dive history.
Listed-price comparison
The price difference is substantial without needing a discount comparison: the Oceanic is listed at $250.00, while the Shearwater Teric is listed at $624.99. The two other choices sit between them.
| Product | Listed price | Price bar |
|---|---|---|
| Shearwater Perdix Wrist Dive Computer - Black - Original OG, NO AI | USD 500.00 | |
| Shearwater Teric Dive Computer Black 55mm | USD 624.99 | |
| Suunto Eon Core Wrist Dive Computer - White with Transmitter And USB | USD 450.00 | |
| Oceanic Dive Computer - USed, 4-5 Dives Only | Full Kit | Factory Screen Pro | USD 250.00 |
Decision matrix
- Readability: The Suunto Eon Core is described with a clear color display and large digits.
- Wrist configuration: The Teric has a 55mm case and silicone band, giving its physical setup a clearly specified format.
- Package scope: The Oceanic includes an extra strap, battery, battery-change tool, PC interface cable, CD, box, and paperwork. The Teric includes a charger, band, case, documents, and carabiner, while the Perdix package is the computer alone.
- Configuration clarity: The Perdix title makes its no-AI setup explicit, while the Suunto title names a transmitter and USB connection.
Shearwater Perdix Wrist Dive Computer - Black - Original OG, NO AI
Choose the Shearwater Perdix when the original or Gen 1 Perdix model is the intended fit. Its title makes the NO AI configuration explicit, and the model name gives shoppers a focused computer choice rather than a broad, unspecified instrument. The limitation is physical condition and package scope: it is used, has scratches across the housing, and may show marks on the screen protector. The buckles are broken with only one arm on the male end, and the package is the computer alone without a box. Those details make the Perdix a focused choice for the unit itself, not for an accessory bundle.
Shearwater Teric Dive Computer Black 55mm
The Shearwater Teric suits shoppers drawn to its named multi-gas decompression function and a package that includes a genuine charger, M/L band, case, documents, and carabiner. That concrete accessory list can simplify the decision for someone who wants more than the instrument alone. Its limitation is the stated accessory scope: power cables and other accessories are specifically excluded. The Teric is also marked used, so its appeal rests on the listed configuration and included items rather than a new-product condition. Choose it when the named decompression function and included charger-and-case package matter more than keeping the purchase at the lower end of the price range.
Suunto Eon Core Wrist Dive Computer - White with Transmitter And USB
The Suunto Eon Core stands out for its combination of a rechargeable battery, updatable software, wireless mobile connection, and customizable settings. The color display with large digits also gives the wrist format a clear readability focus. Its concrete limitation is condition: the unit is used, so the choice is specifically for shoppers comfortable with that status. The transmitter and USB are part of the named configuration, making the Eon Core a natural match for a pressure-data setup rather than someone deliberately seeking a no-air-integration computer. Select it when readable display details and a transmitter-equipped configuration belong together.
Oceanic Dive Computer - USed, 4-5 Dives Only | Full Kit | Factory Screen Pro
The Oceanic choice is centered on the named Atom 3.1 model and the short 4-5-dive history in its title. That gives the lower-priced option a concrete reason to consider, especially for shoppers who want the included extra strap, battery, battery tool, PC interface cable, CD, box, and paperwork. The limitation is that it remains a used computer, and the factory screen protector is still in place. The condition is framed as what you see is what you get, so the Oceanic is best treated as a specific Atom 3.1 kit rather than a generic dive computer category choice.
Final recommendation by use case
- Wireless tank pressure and an underwater compass: Choose the Suunto Eon Core because the transmitter, wireless pressure function, and digital compass are explicitly part of its configuration.
- A no-air-integration wrist computer: Choose the Shearwater Perdix, whose title makes that setup clear and identifies the original OG model.
- Multi-gas decompression: Choose the Shearwater Teric for its named decompression function and specified 55mm wrist format.
- The lower listed-price route with accessories: Choose the Oceanic Atom 3.1 when the full-kit approach and included battery, tool, cable, and paperwork fit the purchase.
The right choice is therefore feature-led: Suunto for pressure and compass functions, Perdix for the no-AI path, Teric for its named decompression configuration, and Oceanic for the lowest listed price paired with a clearly enumerated kit.
