Choosing dive computers & instruments often comes down to one practical trade-off: do you want a proven wrist computer for a specific backup role, or a more complete setup with air integration and fewer condition concerns? The Shearwater Perdix Wrist Dive Computer is aimed at the first buyer, with a clear limitation built into both its configuration and condition.
Quick verdict
At USD 500, the original Gen 1 Shearwater Perdix makes the most sense for a diver who specifically wants a wrist-mounted computer for backup tech diving and is comfortable buying used gear. It does not include air integration, so it is not the right choice if reading tank pressure from the computer is central to your setup.
Who it suits
This Perdix suits someone who already has a primary dive computer or another way to monitor pressure and wants a dedicated backup. Its history of 54 dives and prior use as a backup for tech diving give the purchase a clearly defined role. The listed model is the original Gen 1 version, rather than a newer generation, which matters if you are seeking a current-feature configuration.
It is a less comfortable fit for a diver who wants a complete computer-and-pressure solution in one purchase. The absence of air integration is not a minor detail here; it is the key functional boundary of the configuration.
What stands out from the listed details
The computer is described as working great, with no repair history or reported issues. The screen itself is not cracked, while the visible marks are on the screen protector. The housing also has scratches throughout, giving the unit a clearly used appearance rather than a pristine one.
The package is straightforward: the computer itself, with blue bungees offered to help create straps. That may appeal to a buyer who already has a preferred strap setup, but it also means the purchase does not arrive as a complete boxed package.
Meaningful trade-offs
The biggest practical concern is the damaged buckle hardware: only one arm remains on the male end. That is a concrete reason to budget attention for the strap arrangement rather than treating the included hardware as ready to use. The scratched housing and screen protector add another cosmetic compromise, even though the screen is described as uncracked.
The computer also comes without a box and is explicitly the non-air-integrated model. Those details do not make it unsuitable for backup use, but they narrow the kind of diver who should choose it.
Shearwater Perdix Wrist Dive Computer
Choose the Shearwater Perdix if the original Gen 1 wrist-computer design and its stated backup-tech-diving role match your needs. The limitation is the combination of USD 500 pricing, used condition, broken buckles, and no air integration, so the purchase calls for a buyer who accepts those trade-offs upfront.
Bottom line
This is a focused purchase, not an all-in-one dive computer setup. The Shearwater Perdix is worth considering when a used backup computer is the goal and air integration is unnecessary. If you want intact buckle hardware, minimal cosmetic wear, or integrated pressure information, the listed configuration does not align with that brief.
