Choosing among dive computers & instruments can be tricky because the right fit depends on the job: wireless tank pressure, a tech-diving backup, a multi-gas setup, or a new wrist computer for scuba and snorkeling. The four choices also vary by condition and package contents. Identify the must-have function first, then compare the listed prices.
Quick take
The choices divide into distinct priorities rather than one universal answer. Decide first whether you are assembling around a specific dive function, a backup role, a new-condition purchase, or a named accessory package; then use price as the tie-breaker.
Listed-price comparison

Product notes
Shearwater Perdix Wrist Dive Computer
The Shearwater Perdix Wrist Dive Computer makes sense for a shopper who wants the Perdix model at USD 500.00 and is comfortable with a focused, computer-only purchase. Its 54-dive history gives the choice a concrete usage profile. The limitations are visible: it is used, the housing has scratches, the screen protector is scratched, and one arm on the male buckle end is broken. The sale has no box and includes only the computer, although blue bungees may be included. Choose it for the model and price combination; move on if intact buckles or a complete boxed setup is essential.
Shearwater Teric Dive Computer Black 55mm
With the Shearwater Teric Dive Computer Black 55mm, the reason to choose is the named accessory set: a genuine charger, case, documents, and carabiner are identified alongside the computer. That makes it easy to target if those pieces matter to your setup. The trade-offs are its USD 624.99 price-the highest in this comparison-and used condition. A silicone band and Android compatibility are also specified, but they do not change the cost-and-condition decision. Choose the Teric when the package is worth prioritizing; its listed price is the clearest limitation for shoppers trying to stay near the lower end of this group.
Suunto EON Core Wrist Dive Computer
The Suunto EON Core Wrist Dive Computer is a practical match for shoppers who prioritize readability and flexible operation. It has a clear color display with large digits, a rechargeable battery, wireless mobile connection, and customizable settings. At USD 450.00, it is the lowest listed price here. The limitation is condition: it is used, which matters if a new-condition purchase is the priority. Choose it when a readable screen and adjustable settings fit the way you dive; choose another model when used condition is the deciding constraint.
Shearwater Research Peregrine Adventures Edition Dive Computer
The Shearwater Research Peregrine Adventures Edition Dive Computer suits a shopper who places new condition ahead of the lowest price. The title clearly identifies the Adventures Edition, while the product identifies the Peregrine model and a quantity of one unit. At USD 499.99, its listed price is not the lowest in this comparison. That price is the main limitation for a shopper focused only on the least expensive route, while the one-unit package sets a concrete boundary for multi-unit planning. Choose it when new condition and the Adventures Edition title match the purchase; the package quantity is the detail to weigh.
Final recommendation by use case
- Air-integrated scuba: Choose the Suunto EON Core. Wireless tank pressure and a digital compass are explicit, making its role clear.
- Tech-diving backup without air integration: Choose the Shearwater Perdix only if the used condition, scratches, and broken buckle are acceptable.
- Multi-gas use with a named package: Choose the Shearwater Teric when its charger, case, documents, and carabiner matter enough to justify its listed price.
- New-condition scuba computer: Choose the Peregrine Adventures Edition. Its new condition and scuba-and-snorkeling positioning match that brief.
If two routes still fit, use the listed price as the tie-breaker rather than treating the price bars as a capability ranking.
