Start with the dives you are trained to make and the display you can read comfortably. Air integration adds cylinder information when paired with compatible transmitters; it does not replace gas planning.
Shearwater Perdix 3
For room to grow into technical diving. A 2.4-inch AMOLED display and replaceable AA battery anchor this 260 m-rated platform. Includes recreational modes, open-circuit technical trimix, fixed-PPO2 closed-circuit/bailout, gauge and freediving.
Why choose it?
Digital compass, vibration alerts and support for four transmitters combine extensive information with configurable screens. Check approved battery types: vibration support depends on the battery.

Why choose it?

Swift GPS: pressure information plus surface locations
Shearwater Swift GPS transmitter
This tank-mounted accessory combines wireless pressure transmission with GPS coordinates captured at the surface. Entry and exit locations can appear in the Dive Shearwater app. GPS does not work underwater.
Compatible with Shearwater air-integrated computers with the required firmware. A replaceable CR2 battery, collision-avoidance technology and a 200 m rating support the system. Confirm compatibility before ordering; Swift GPS and the original Swift are different products.
Try your normal dive mask and compare the information at a realistic wrist distance. Consider screen size, button access with gloves, battery preference and whether your future training needs technical modes.
