Choosing dive computers & instruments comes down to matching the computer to your setup, not simply choosing the highest or lowest price. Air integration, wireless tank pressure, compass functions, wrist format, condition, and included accessories create very different buying decisions for scuba divers.
Quick take
The listed prices span USD 397.50 to USD 624.99. The main split is between computers with named air-pressure functionality, a compass-focused setup, a specific case format, or a model-specific used unit. Condition also varies: three choices are marked Used, while the Oceanic is marked New other (see details).

Decision matrix
- Air-integrated Air/Nitrox functionality and a compass: The Oceanic Pro Plus 3 has both functions named in its title and description.
- Wireless tank pressure, compass, and a transmitter: The Suunto Eon Core title names a transmitter, while its description identifies wireless tank pressure and a digital compass.
- An original Gen 1 model without air integration: The Shearwater Perdix description specifically identifies that configuration.
- A 55mm case with a silicone band: Those are the listed format details for the Shearwater Teric.
Product notes
Shearwater Perdix Wrist Dive Computer
A concrete reason to choose the Shearwater Perdix is its described original Gen 1 identity and prior role as a backup for tech diving, which will appeal to someone seeking that specific model. The limitation is physical condition: it is marked Used, with scratches on the housing, a screen protector whose underlying scratches are uncertain, and a buckle with only one arm on the male end. The package is described as the computer alone, without a box. At USD 500.00, it sits between the Suunto and Teric in listed price, so the wear details are central to the decision.
Shearwater Teric Dive Computer Black 55mm
The package details are the main reason to consider the Shearwater Teric. The description names a genuine charger, case, documents with carabiner, and M/L band alongside the computer, giving the purchase a clearly identified set of included components. Its limitation is the price position: USD 624.99 is the highest listed price among the four, and the condition is marked Used. Choose it when the named accessories and the Teric format matter more than keeping the purchase at the lower end of the range. The listed silicone band is another concrete detail for shoppers comparing the physical setup.
Suunto Eon Core Wrist Dive Computer
The Suunto Eon Core brings several practical details together: a clear color display with large digits, a rechargeable battery, updatable software, and customizable settings. Those features make it a sensible choice for a diver who wants a wrist computer with an adjustable, rechargeable setup rather than a purely basic instrument. The limitation is condition, which is marked Used. The title also specifies a white computer with USB, so the visible finish and named connection accessory are part of the selection. At USD 450.00, it occupies the second-lowest listed-price position without being the price floor.
Oceanic Pro Plus 3 Dive Computer With Compass
The Oceanic Pro Plus 3 is aimed at shoppers who want readable information and a feature-rich named configuration. Its description highlights a large display area and large digits, while the package wording includes a spare battery, O ring, and download cable. The title and description also identify a compass and full-function air-integrated Air/Nitrox capability. The limitation is the condition label: it is marked "New other (see details)," so that wording belongs in the purchase decision. Its listed price is USD 397.50, the lowest in this comparison, making it the natural starting point for a price-led choice.
Final recommendation by use case
- Lowest listed price: Choose the Oceanic Pro Plus 3 at USD 397.50 if its compass and air-integrated Air/Nitrox functions match your requirements.
- Wireless tank-pressure setup: Choose the Suunto Eon Core when the named transmitter, wireless tank pressure, and digital compass are the priority.
- Specific original model: Choose the Shearwater Perdix when the original Gen 1 configuration matters and the stated Used condition, scratches, and buckle wear are acceptable.
- 55mm format: Choose the Shearwater Teric when its 55mm case and named package contents justify the highest listed price of USD 624.99.
