This is my first diving computer. It took me some time to search and read about the the differnt diving computers types. Until I decided to get this one. It is easy to use, looks great on the arm, not heavy, screen size is excellent (unlike other computers where they have a big screen). This one you can have it on your hand all day with no issue. Also, the strap size is prefect (not long similar to some of the other types). And I received it in a good condition. Still I need some time to get used to it but overall, I am happy with this device.
