Choosing dive computers & instruments is less about finding one universal pick and more about matching the computer to your diving setup. The important tradeoffs here are air-integration equipment, a specific Teric configuration, the condition of an original Perdix, and whether you want a new Peregrine. The listed prices span $499.99 to $899.99, so the right choice depends on which details you will actually use.
Quick take
Start with the configuration rather than the model name. The two Teric entries represent different package decisions, the Perdix is an original used configuration with visible wear, and the Peregrine is the new choice at the lower end of the range. The sections below separate those paths without treating shared dive-computer basics as a differentiator.

Product notes
Shearwater Teric Dive Computer Black 55mm
At USD 624.99, the Shearwater Teric Dive Computer Black 55mm suits a shopper who wants the Teric in a clearly identified 55mm case. Its description lists multi-gas decompression, a silicone band, Android compatibility, a genuine charger, case, documents, and carabiner, giving the package a clear identity apart from the transmitter bundle. The limitation is the used condition, and its listed price is $125.00 above the lowest listed price. The title identifies the black 55mm computer rather than the Teric configuration that names an air-integration transmitter. Choose it for the specific case size and charger/case package; look elsewhere if new condition or air integration is the deciding requirement.
Shearwater Teric Dive Computer w/ Air Integration Transmitter, Charger
Air integration is the reason to focus on the Shearwater Teric Dive Computer w/ Air Integration Transmitter, Charger. The description names a full-color AMOLED display with sapphire crystal, wireless air integration, Air, Nitrox, Trimix, Tech, CCR and Freediving modes, a digital compass, Bluetooth, a wireless rechargeable battery, audible and vibration alerts, and a 200 m / 660 ft depth rating. Its concrete limitation is the USD 899.99 listed price, the highest in this group, plus used condition. Choose it when the transmitter and named feature set matter more than keeping the purchase at the lower end.
Shearwater Perdix Wrist Dive Computer - Black - Original OG, NO AI
The Shearwater Perdix Wrist Dive Computer - Black - Original OG, NO AI is the clearest fit for someone specifically seeking the original Perdix configuration without air integration. Its description says it was used as a backup for tech diving and records 54 dives, while the title identifies the OG, NO AI configuration. The tradeoff is condition: scratches are described on the housing, the screen protector is scratched, the buckles are broken, and the sale is described as the computer only with no box. At USD 500.00, it sits just above the Peregrine's USD 499.99 price. Choose the Perdix only if those condition details fit your expectations.
Shearwater Research Peregrine Adventures Edition Dive Computer
For a new unit at the low end, the Shearwater Research Peregrine Adventures Edition Dive Computer is the most direct match. It is identified as New, Model: Peregrine, and a single unit; its description positions the wrist computer for scuba and snorkeling and names decompression calculations and dive profiling. The limitation is its Peregrine identity: buyers who specifically want the Teric package named with an air-integration transmitter will need a different configuration. At USD 499.99, it is $400.00 below the highest listed price. Pick it when new condition and the Peregrine scuba and snorkeling use case matter most.
Final recommendation by use case
- For an air-integration setup: choose the Shearwater Teric Dive Computer w/ Air Integration Transmitter, Charger.
- For the named 55mm Teric configuration: choose Shearwater Teric Dive Computer Black 55mm.
- For an original Perdix and no-AI setup: choose Shearwater Perdix Wrist Dive Computer - Black - Original OG, NO AI, provided its wear and broken buckles are acceptable.
- For a new scuba or snorkeling computer: choose Shearwater Research Peregrine Adventures Edition Dive Computer.
The $400.00 listed-price spread is meaningful, but it should follow the configuration decision rather than replace it. Match the named package, condition, and intended use first; then use price to separate the remaining candidates.
