Shearwater Perdix 3 Dive Computer

The Perdix 3 is Shearwater’s newest flagship computer, designed for divers who want a bright, durable, and reliable platform that works for recreational, technical, and rebreather diving. It keeps the familiar Perdix form factor but upgrades the screen, materials, and interface for better visibility and long term durability.

Key Features

Brighter and larger AMOLED display

The Perdix 3 uses a high contrast AMOLED screen that is easier to read in low visibility, overhead environments, and bright surface conditions. The display is larger than previous Perdix models and offers improved color clarity for critical information.

Titanium bezel and reinforced body

The new titanium bezel increases impact resistance and reduces long term wear. The body is reinforced for better durability in demanding environments including wrecks, caves, and heavy training use.

Upgraded vibration alerts

The Perdix 3 includes strong vibration alerts that are easy to feel through gloves and exposure protection. This is especially useful for deco stops, gas switches, and attention critical alarms.

Air integration ready

The Perdix 3 supports up to four Swift transmitters for tank pressure monitoring. This makes it suitable for single tank, sidemount, and multi stage technical configurations.

Multiple dive modes

• Recreational Nitrox
• Three gas Nitrox
• Open circuit technical
• Closed circuit fixed setpoint
• Gauge mode

Shearwater user interface

The two button interface remains simple, predictable, and easy to use underwater. Menus are clean and navigation is consistent across all Shearwater models.

Bluetooth connectivity

Wireless syncing with Shearwater Cloud for logs, firmware updates, and configuration.

User replaceable AA battery

The Perdix 3 continues to use a standard AA battery. This makes field replacement easy and avoids proprietary charging systems.
