- Descent S1 Diver Communication Buoy -
Discover a deeper connection with the Descent S1 diver communication buoy. When paired with up to eight Descent T2 transceivers (sold separately) and the Garmin Dive smartphone app, the buoy enables topside crew to monitor and exchange preset messages with divers wearing compatible dive computers. (Some compatible dive computers can receive, but not send, messages. Conditions such as surface, waves, chop, objects and diver position can obstruct the signal and reduce range.) Those on the surface can use the Garmin Dive app to see the diver's tank pressure, depth and distance. Surface users can also send preset messages to divers below to alert them of situations that need attention. For positional awareness, divers can track their distance and direction back to the Descent S1 buoy. Once they've surfaced, divers can also sync and review heatmaps of their underwater activity in the Garmin Dive app to gain a better picture of approximately where they were diving. Plus, with a battery life of up to 15 hours, the Descent S1 diver communication buoy can be deployed for a full day of diving before needing a recharge.
- Descent Mk3i 51mm Dive Computer Smartwatch -
Discover a deeper connection with the Descent Mk3i watch-style dive computer. It features multiple dive modes plus SubWave sonar technology for diver-to-diver communication via preset messages (available with software v.15.70 or later). The device also supports monitoring of tank pressures and depth for up to eight networked divers, when paired with the Descent T2 transceiver (sold separately). Purpose-built specifically for divers, the Descent Mk3i dive computer combines a bright 1.2" AMOLED display with scratch-resistant sapphire lens, 200-meter dive-rated case and metal leakproof inductive buttons. DiveView maps offer bathymetric depth contours and more than 4,000 dive sites to help you find where to dive and get oriented. Plus, a dive readiness tool, developed by Garmin, shows how lifestyle factors such as sleep, exercise, stress and jet lag can affect your body's overall preparedness for diving - so, ultimately, you can make better-informed dive plan decisions (data presented is intended to be a close estimation of metrics tracked).
This dive computer is designed to help maximize your preparation for the physical and mental challenges of diving. You can also reference ABC sensors with a 3-axis underwater compass as well as surface GPS capabilities to mark your entry and exit points. When you're ashore, built-in sports apps help you stay on top of your fitness, while Garmin Pay contactless payments, music storage and smart notifications keep you connected (compatible smartphone required).
- Descent T2 Transceiver -
Add Diver Communication To Tank Pressure Monitoring
Every breath, every tank, every buddy on your dive - track them all on your wrist when you pair the Descent T2 transceiver with your compatible air-integrated Descent dive computer.
Enhanced SubWave sonar technology lets you monitor up to 8 tanks when under water - viewing air pressure, depth, use rate and time remaining - for multiple types of diving. Plus, you can even communicate via preformatted messages with other networked buddies wearing their Descent Mk3i dive computers.
Dive with added confidence and situational awareness.
Deep Dive-Rated
Built to withstand the elements, the Descent T2 transceiver is dive-rated to 20 ATM (200 meters) - so you can dive deeper without worry.
Know Your Tank
Get tank pressure, air time remaining, air consumption rate and battery remaining - all sent directly to your paired air-integrated Descent dive computer.
Link Multiple Divers
See your dive buddies' tank pressures and depths at a glance. Pair up to 8 transceivers on your group's tanks with each compatible air-integrated dive computer within a range of up to 10 meters.
Diver Messaging
Exchange preformatted diver-to-diver messages with other Descent T2 transceiver-networked buddies wearing Descent Mk3i dive computers up to 30 meters away.
Easy Tank ID
A simplified pairing process using wireless area networking makes it easy to identify your buddies' names with the Descent T2 tank transceivers they're wearing.
