Choosing among dive computers & instruments is less about finding one universal pick and more about resolving a specific trade-off: wireless tank information and a compass, technical gas and mode controls, a particular wrist format, or a lower listed price. Match the instrument to the feature you will actually use, then weigh condition and included gear.
Quick take
- Shearwater Perdix Wrist Dive Computer: Pick it for the *Original OG* model wording and wrist format; the described housing and buckle wear should be part of the decision.
- Shearwater Teric Dive Computer Black 55mm: Pick it for the 55mm case and named charger-and-case kit; it sits at the high end of this price comparison.
- Suunto EON Core Wrist Dive Computer: Pick it for the transmitter and USB combination named in the title, along with its wrist format.
- Deep 6 Excursion Scuba Dive Computer: Pick it for the recreational-and-technical title and listed mode set; it sits at the low end of the price comparison.
Listed-price comparison
The listed prices run from USD 199.00 to USD 624.99, a $425.99 spread. The bars show relative listed-price position, not performance.

Product notes
Shearwater Perdix Wrist Dive Computer

The Shearwater Perdix Wrist Dive Computer fits a shopper drawn to the *Original OG* model in a wrist format. Its listed condition is Used, and the description gives specific wear: scratches across the housing and screen protector, plus a male buckle end with only one arm. The sale is described as the computer alone, with blue bungees offered as an addition. Those physical details are the limitation, especially for anyone wanting an intact buckle. Choose the Perdix when the named model and wrist format are the priority and cosmetic wear is acceptable.
Shearwater Teric Dive Computer Black 55mm

The Shearwater Teric Dive Computer Black 55mm makes sense for a shopper focused on the listed multi-gas decompression capability. Its description names a genuine charger, case, documents with carabiner, and M/L band, while the attributes specify a silicone band and 55mm case size. The limitation is its Used condition, which makes condition a central part of the purchase decision. Choose the Teric when multi-gas decompression matters more than selecting a lower-priced computer; its title gives the case size plainly.
Suunto EON Core Wrist Dive Computer

The Suunto EON Core Wrist Dive Computer suits shoppers who care about a rechargeable battery and wireless mobile connection. Its description also names a color display with large digits, giving it a clear readability angle for scuba sessions. The limitation is the Used condition, so it is not the match for a shopper whose first filter is a New unit. Choose the EON Core when those display and battery features fit the plan. The white wrist format and transmitter named in the title make its intended setup easy to identify.
Deep 6 Excursion Scuba Dive Computer for Recreational and Technical Diving New

Deep 6 Excursion Scuba Dive Computer for Recreational and Technical Diving New is a fit for shoppers who want the listed New condition alongside Bluetooth logging and updates. Its description also names variable-brightness backlight, fast-charging mode, and scuba, planning, apnea/free diving, and gauge modes. It lists Nitrox and Helitrox ranges without saying that one numeric range is better than another. The limitation is fit: someone specifically seeking Suunto's wireless mobile connection should prioritize that stated function instead. Deep 6 fits when its recreational-and-technical title and control modes align with the planned diving.
Final recommendation by use case
- Wireless tank information and compass: Choose the Suunto EON Core Wrist Dive Computer, whose description names both functions.
- Multi-gas decompression: Choose the Shearwater Teric Dive Computer Black 55mm, with that capability stated in its description.
- A no-air-integration wrist setup: Choose the Shearwater Perdix Wrist Dive Computer, whose configuration is explicitly described that way.
- A New-condition purchase with Bluetooth logging and updates: Choose Deep 6 Excursion Scuba Dive Computer, which lists both attributes.
The deciding question is not which computer has the longest feature list. It is whether your priority is air information, technical controls, the Original OG wrist format, or a New-condition instrument at the low end of the listed price range.
