Exclusive SubWave sonar technology emits 360-degree spherical sound waves underwater, breaking the limits of traditional transceivers and enabling long-distance, bidirectional underwater text message transmission while also displaying the remaining air pressure in your dive buddy's tank.
The Descent T2 transceiver, paired with the Descent Mk3i and Descent X50i diving computer, uses SubWave sonar technology to enable diving buddies to exchange text messages underwater to a maximum range of 30 meters. In poor underwater visibility or night diving, you can read and reply to messages directly on the wristwatch, enabling clear and effortless communication underwater. This marks a new era in underwater communication.
The Descent T2 features an even more sensitive sonar transceiver module. Within a 10-meter range underwater, your smartwatch can connect to as many as eight Descent T2 transceivers. So as well as viewing your own tank pressure, surface air consumption rate (SAC), and air time remaining (ATR), you can also monitor the air pressure of diving companions, while tracking additional information such as the distance and direction of your dive buddy.
The Descent Mk3 features an innovative dive readiness indicator which combines Garmin's decades of experience in wearables with insights from collaborators Firstbeat Analytics. It collates recent user information on sleep, physical activity, stress, jet lag and so on to calculate risk indicators for decompression sickness and provide diving activity recommendations that assist you to make wiser, safer diving plans.
Nitrogen is dissolved in body tissues while you dive; how much depends on how deep you dive and how long you are under water. Displaying your N2 loading helps you monitor nitrogen levels and avoid nitrogen narcosis.
The partial pressure of oxygen (PO2) in mixed gas is monitored to gauge central nervous system (CNS) oxygen toxicity, reducing risk of seizures due high CNS oxygen toxicity over extended periods. (Alarm: 1.4 ata / Limit: 1.6 ata)
These figures indicate the maximum time a diver can remain at a given depth.If a diver exceeds the NDL, the risk of decompression sickness increases significantly.
During an ascent, divers must pause at specific depths to allow for the release of excess nitrogen in the body. Before surfacing they must remain at a depth of five metres for three minutes, a 'safety stop' that reduces the risk of decompression sickness.
The Garmin inReach Mini 2 Satellite Communicator provides worldwide text communication coverage via the Iridium satellite network. If you are drifting at sea, you can send an SOS distress message directly to the Garmin Response international emergency coordination center, which operates year-round. It will connect with local search and rescue units to launch a rescue response. When paired with a diving case accessory, it can accompany you to depths of up to 100 meters.
Garmin inReach Mini 2When you're freediving, constantly checking your dive computer can waste valuable time. The Garmin Descent smartwatches uses a range of audio and vibration alerts to make freedivers aware of their current situation, reducing the need to frequently check your dive computer.
Variometer and high and low-speed alarms can be used to help maintain a specific ascent and descent rate, reminding freedivers to keep to their target speed and adjust their kicking frequency.
Alerts can be set for when you reach specific depths or depth intervals (e.g., every 10 meters), and you can set reminders for neutral buoyancy and target depth.
VO2 Max refers to the maximum amount of oxygen the body can absorb and utilize within one minute. By engaging in daily aerobic and anaerobic training, you can increase your VO2 Max, allowing you to maintain an optimal level of fitness.
