Overview
SubWave sonar technology lets divers exchange preset messages, available with a recent software version. The Mk3i adds multiple dive modes, a titanium case and DiveView maps with bathymetric contours for finding dive sites.
Beyond diving it works as a smartwatch, with music storage, contactless payment and smart notifications when paired with a phone. A dive readiness tool estimates how sleep and stress may affect preparedness. Garmin notes the data is a close estimation.
Who it's for
A recreational or technical diver who values a bright AMOLED screen and diver-to-diver messaging. Anyone who needs a transceiver for tank pressures must buy it separately, and a buyer with a small wrist should check the case size.
Pros and cons
- Titanium case, sapphire lens
- SubWave sonar messaging
- Large AMOLED display
- Smartwatch features on land
- Transceiver sold separately
- Metrics listed are depth only
- Needs phone for notifications
Performance notes
The depth sensor, compass and GPS handle dive tracking, and sonar sends short preset messages between divers who also own compatible units. Tank pressure monitoring for networked divers needs the optional transceiver. Battery life depends on which features run.
