How the Features Help
- Reading the display: Colour presentation separates key data such as depth, dive time and gas information. Set brightness and the available screen layout before entering the water so the information you use is easy to find.
- Navigation: A digital compass brings heading information to the same instrument as your dive data. Calibrate it as instructed and practise the available bearing and reciprocal-heading functions on the surface.
- Cylinder-pressure information: With the specified compatible transmitter, the computer shows cylinder-pressure data at your wrist. Pair each transmitter to its correct gas and check the surface reading; gas-time estimates support your existing gas plan.
- Power between dive days: A rechargeable battery avoids routine disposable-cell changes. Use the specified charging accessory and allow the instrument and electrical connections to dry before charging.
- Freediving records: The applicable freediving mode records breath-hold dive and surface information separately from scuba operation. Configure prompts for your training plan and follow the manual’s restrictions on changing between modes.

Choosing and Setting Up This Model
Compare the modes, gas capability, display and mounting arrangement with the diving you are trained to do. Check exactly what this listing includes, particularly transmitters, interfaces and charging accessories. Configure the computer using its own manual and confirm gases, alerts, units and battery status before diving. A depth rating describes an instrument limit and does not establish a suitable dive depth.
Gear Care and Maintenance
After every dive, rinse gently in fresh water to remove salt, chlorine and grit. Let residue soften by soaking only as the model’s manual permits, and operate buttons during rinsing only where instructed. Do not direct a high-pressure hose or compressed air at sensor openings, and never probe them with a tool.
Suunto permits gentle cleaning with fresh water and mild soap, using a soft damp cloth on the housing. Rinse thoroughly, then let the computer, strap and charging points dry fully in the shade. Avoid solvents, abrasives and direct heat.
Inspect the strap, attachment points, display and seals before use. Store in a cool, dry place away from direct sunlight, heaters and hot cars, with the screen protected from loose equipment. Follow the manufacturer’s battery-storage and servicing instructions.
Charge only with the compatible charger or adapter and the specified power source. Dry electrical contacts before connecting and follow the manual’s charging temperature and long-term battery-storage instructions. Rechargeable internal batteries are serviced only as the manufacturer permits.
