Dive Computers & Instruments: Choose Air Integration, a Compass, or a Lower Price

Compare four dive computers & instruments by air integration, compass features, included accessories, condition, and listed price so you can match the package to your diving setup.

Last updated Aug 26, 2026

Choosing dive computers & instruments comes down to a practical split: do you want an included air-integration transmitter, a compass called out in the package, a particular Teric or Perdix format, or a lower entry price? These four choices suit different setups. Match the named hardware and condition to your intended use, then use price as the tie-breaker.

Quick take

  • For an included transmitter: Shearwater Teric Dive Computer w/ Air Integration Transmitter, Charger.
  • For a compass and air-integrated computer: Oceanic Pro Plus 3 Dive Computer With Compass LOOKS LIKE NEVER WET! Nice.
  • For the 55mm Teric format: Shearwater Teric Dive Computer Black 55mm.
  • For an original Perdix without air integration: Shearwater Perdix Wrist Dive Computer - Black - Original OG, NO AI.

The price range runs from USD 397.50 to USD 899.99, a USD 502.49 spread. The packages differ notably: one includes a transmitter, one emphasizes a compass and air integration, one includes a Teric case and charger, and one is described as the computer alone.

Decision matrix

  • Air-integration hardware: The Shearwater Teric package with transmitter is the direct match when that included component is central to the purchase. The Oceanic description names full-function air integration, while the Perdix description explicitly says it is without air integration.
  • Compass use: The Oceanic title calls out a compass, and the transmitter-equipped Teric description lists a digital compass. Those are the clearest choices when compass functionality matters.
  • Teric package details: The 55mm Teric includes a genuine charger, case, documents, and an M/L band. The other Teric package emphasizes AMOLED display technology, wireless charging, alerts, and multiple operating modes.
  • Condition and included items: The Perdix description mentions scratches, a broken buckle, and no box. The Oceanic condition is labeled New other (see details), while the two Teric products are listed as used.

Product notes

Shearwater Teric Dive Computer Black 55mm

Shearwater Teric Dive Computer Black 55mm

The Shearwater Teric Dive Computer Black 55mm suits shoppers who want a specifically sized Teric with a defined accessory package. Its 55mm case, silicone band, multi-gas decompression description, genuine charger, Shearwater case, documents, and M/L band give the purchase a clear equipment outline. Android compatibility is also named. The main limitation is the used condition, along with the instruction that accessories not specifically listed are not included. Choose it when the 55mm Teric format and included case-and-charger setup matter more than adding the separately described transmitter package.

Shearwater Teric Dive Computer w/ Air Integration Transmitter, Charger

Shearwater Teric Dive Computer w/ Air Integration Transmitter, Charger

The Shearwater Teric Dive Computer w/ Air Integration Transmitter, Charger is the clearest match for a setup centered on wireless gas monitoring. Its title names the transmitter, and the description adds a full-color AMOLED display, sapphire crystal, digital compass, Bluetooth connectivity, wireless rechargeable battery, audible and vibration alerts, and Air, Nitrox, Trimix, Tech, CCR, and Freediving modes. That breadth gives shoppers several named functions in one package. The limitation is the used condition. Pick it when the transmitter, wireless air integration, and broad mode selection are more important than keeping the package simple.

Shearwater Perdix Wrist Dive Computer - Black - Original OG, NO AI

Shearwater Perdix Wrist Dive Computer - Black - Original OG, NO AI

Shearwater Perdix Wrist Dive Computer - Black - Original OG, NO AI fits someone seeking the original Gen 1 Perdix format without air integration. The description identifies it as an OG Shearwater Perdix and says it was used as a backup for technical diving, which gives the computer a defined role. The tradeoffs are concrete: scratches are described on the housing, the screen protector has scratches, the buckles are broken with one arm on the male end, and the package contains only the computer. Choose it only when the original Perdix identity and computer-only setup outweigh those condition and accessory limitations.

Oceanic Pro Plus 3 Dive Computer With Compass LOOKS LIKE NEVER WET! Nice

Oceanic Pro Plus 3 Dive Computer With Compass LOOKS LIKE NEVER WET! Nice

Oceanic Pro Plus 3 Dive Computer With Compass LOOKS LIKE NEVER WET! Nice is the price-led choice for shoppers drawn to a compass and air-integration functions in one package. The description calls out a large display area, legible digits, Air/Nitrox operation, user-changeable dual algorithms, a download cable, spare battery, O-ring, and computer gauge guard. The compass is explicit in the title, while full-function air integration appears in the description. Its limitation is the New other (see details) condition label rather than standard new condition. Choose it when the display emphasis and named accessories fit your setup.

Final recommendations by use case

  • Choose the transmitter-equipped Teric when wireless air integration is the deciding feature and the listed modes, alerts, and digital compass also appeal.
  • Choose the Oceanic Pro Plus 3 when a compass, Air/Nitrox operation, large display emphasis, and included cable and battery are the strongest priorities.
  • Choose the 55mm Teric when the case size, silicone band, charger, and case provide the right Teric package.
  • Choose the original Perdix when you specifically want a Gen 1 computer without air integration and can accept the scratches, broken buckle, and computer-only contents.
