This dive computer is my first one. Of course, I have used many others and I liked this one more. It is made of excellent materials and has a discreet design that allows it to be used as an everyday watch.
In use as a watch, in addition to the basic functions of a watch, it has a second time zone, a stopwatch, a countdown timer, and an alarm.
In use as a dive computer (for autonomous and free diving), it has a no-decompression dive time function, dive profile programming, audible alarms for exceeding limits, NITROX mode, second gas mix, automatic activation in water, altimeter and temperature sensor, strap extension, dive log calendar, and special software for transferring dive data to a computer.
Also, its screen is large with readable indications and the sound warnings or alarms are quite loud. Its menu is quite user-friendly.
Advantages: User-replaceable battery (no need to send it to the service center, which costs money), low price.
Disadvantages: I haven't found any yet.
I recommend it to all new divers.
