Choosing dive computers & instruments comes down to matching the computer's gas-management setup, format, and condition to the way you dive. The main decision here is whether you want a transmitter-included Teric, a computer centered on multi-gas and technical modes, a defined 55mm Teric format, or a used Perdix with visible wear. The comparison below keeps those paths separate so the price range does not blur the differences.

Product notes
Shearwater Teric Dive Computer Black 55mm
Shearwater Teric Black 55mm is the practical match for shoppers who want the named case size and silicone band. Its description also identifies multi-gas decompression capability and names a genuine charger, case, documents, and carabiner among the included items. Android is listed as the compatible operating system, adding a concrete fit for shoppers who use that platform. The limitation is condition: the computer is listed as Used. The package description also draws a clear line around what is included, so the charger and case are named inclusions while extra accessories should not be assumed. Choose this Teric when its format matters more than the transmitter-included package attached to the other Teric.
Shearwater Teric Dive Computer with Air Integration Transmitter and Charger
The Shearwater Teric with Air Integration Transmitter, Charger is the direct match for shoppers who want the transmitter explicitly named in the title. Its description adds wireless air integration, a full-color AMOLED display with sapphire crystal, 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. That gives the package a clearly defined feature and accessory scope. The limitation is condition: it is listed as Used. The many named modes and included components also make this a specific purchase brief rather than a simple computer-only choice.
Shearwater Perdix Wrist Dive Computer - Original OG
Shearwater Perdix Wrist Dive Computer - Original OG suits shoppers who specifically want the named Perdix model and a setup without air integration. The description identifies it as a Gen 1 computer and says it was used as a backup for tech diving, giving the model a clear role. The limitation is physical condition and package scope: scratches are noted on the housing, the screen protector may conceal deeper marks, the buckles are broken, and the package includes no box and only the computer, with blue bungees offered for creating straps. That wear makes strap replacement and cosmetic condition part of the choice.
Deep 6 Excursion Scuba Dive Computer
Deep 6 Excursion Scuba Dive Computer for Recreational and Technical Diving New is the fit for shoppers prioritizing named multi-gas and configuration tools. The description lists Nitrox from 20%-99% across four gases, Helitrox up to 22% helium, the Bühlmann ZHL-16C algorithm, user-settable gradient factors, Scuba, Planning, Apnea/Free Diving and Gauge modes, Bluetooth, variable brightness, and fast charging. It also identifies a New condition and the Excursion model. The limitation is model emphasis: shoppers focused on the Shearwater Teric or Perdix names are choosing a different computer, with the description centered on dive modes and settings rather than the transmitter-included Teric package.
Final recommendation by use case
- For a transmitter-led setup: The Shearwater Teric Dive Computer w/ Air Integration Transmitter, Charger is the direct match because its title names both the computer and transmitter, while the description names wireless air integration.
- For multi-gas configuration: The Deep 6 Excursion is the clearest fit for its named Nitrox, Helitrox, gradient-factor, and planning features.
- For a defined physical format: The Shearwater Teric Dive Computer Black 55mm fits shoppers focused on the listed case size, silicone band, charger, and case.
- For the original Perdix identity: The Shearwater Perdix Wrist Dive Computer - Original OG makes sense when the named Gen 1 model and non-air-integrated setup matter more than cosmetic wear and broken buckles.
The deciding question is whether your priority is the transmitter package, configurable dive modes, a specific Teric format, or the original Perdix model. Once that is clear, the listed-price spread becomes a secondary choice rather than the only deciding factor.
