While it has many strengths, there are a few drawbacks to consider. The need for a separate Descent T2 transceiver for full functionality with tank pressure monitoring may be off-putting for some users who prefer an all-in-one solution. The size and weight, while manageable at 105.6 grams, may feel bulky to users accustomed to simpler dive watches. Furthermore, while the dive log feature is an excellent way to keep track of dives, it may lack some advanced analytics that dedicated dive log software could provide.

Additionally, the optional wireless air integration with the Shearwater Swift Transmitter provides real-time gas pressure data, helping divers manage their air supply more accurately during dives.

The inclusion of a tilt-compensated digital compass is a great bonus, ensuring you can maintain your heading underwater, which is essential for navigation. The rechargeable battery is another strong point, offering up to 30 hours of diving time, allowing for extended dive trips without worrying about battery life. The Bluetooth connectivity to Shearwater Cloud for tracking dive data adds a modern touch, making it convenient to log and review your dives.
