Choosing among dive computers & instruments means resolving a practical split before comparing screens: do you want a wrist computer, a console, or a package that names extra equipment such as an air-integration transmitter? These four choices span $297.50 to $899.99, a $602.49 spread. The right pick depends less on one headline specification than on format, included accessories, configuration, and condition.
Quick take
There are two Teric choices, one Perdix, and one Aqua Lung I330R-2. Start with format and configuration, then use the included equipment and condition to break ties. The main decision is not simply which number is largest or smallest; it is whether the named setup matches the way you plan to use a dive computer. Each choice has a concrete configuration and trade-off.

Product notes
Shearwater Teric Dive Computer Black 55mm
The Shearwater Teric Dive Computer Black 55mm is a strong match for someone who wants a Teric with a defined 55mm case and silicone band. Its package includes multi-gas decompression, a genuine charger, an M/L band, a case, documents, and a carabiner, creating a clear accessory bundle. The limitation is its used condition: it has no manufacturer warranty, while a 30-day warranty is stated for the item. At $624.99, it sits between the two Teric configurations and the other two computers, so the included accessories matter in the choice.
Shearwater Teric Dive Computer w/ Air Integration Transmitter, Charger
Shearwater Teric Dive Computer w/ Air Integration Transmitter, Charger is the direct pick for a diver who wants air integration and charging equipment named together in one package. It also specifies a full-color AMOLED display with sapphire crystal, a digital compass, Bluetooth connectivity, wireless rechargeable battery, audible and vibration alerts, and a 200 m / 660 ft depth rating. Its limitation is straightforward: it is marked used and has the highest listed price among the four choices. The package makes sense when the transmitter, charging station, and broad set of named modes are central to the purchase.
Shearwater Perdix Wrist Dive Computer - Black - Original OG, NO AI
Shearwater Perdix Wrist Dive Computer - Black - Original OG, NO AI is a focused choice for someone who intentionally wants the original Perdix configuration without air integration. It is identified as an OG Gen 1 unit, and its model is specified as Perdix. The trade-off is physical condition and completeness: it is used, the housing has scratches, the screen protector has scratches, the buckles have a broken arm, and the package includes only the computer with no box. At $500.00, its appeal rests on the stated original, no-AI setup rather than bundled accessories.
AQUALUNG DIVE COMPUTER I330R-2 WAY COLL DIGITAL SYSTEM WITH QUICK DISCONNECT
AQUALUNG DIVE COMPUTER I330R-2 WAY COLL DIGITAL SYSTEM WITH QUICK DISCONNECT makes sense when you are shopping for a console-style instrument rather than a wrist computer. It includes a bright color display readable in sunlight, a rechargeable battery, Bluetooth, Diverlog+ app connectivity, four modes, three nitrox mixes, and compass compatibility. The concrete limitation is format: the title identifies a 2-gauge console with quick disconnect, so it is not the natural match for a wrist-focused setup. It is marked New other (see details), a different condition label from the three used Shearwater computers. At $297.50, it is the lowest listed price.
Final recommendation by use case
- Air integration: Choose Shearwater Teric Dive Computer w/ Air Integration Transmitter, Charger for the package that explicitly names the transmitter.
- Specified Teric configuration: Choose Shearwater Teric Dive Computer Black 55mm when that stated size and accessory bundle fit your plan.
- Original Perdix configuration: Choose Shearwater Perdix Wrist Dive Computer - Black - Original OG, NO AI when the no-AI setup is intentional and the condition trade-offs are acceptable.
- Console format: Choose AQUALUNG DIVE COMPUTER I330R-2 WAY COLL DIGITAL SYSTEM WITH QUICK DISCONNECT for the console path and its bright display, rechargeable battery, and quick-disconnect format.
