Up for review today is a dive computer wristwatch from a lesser known Italian company: The Immersion Prowler. It's a digital data logger, dive computer, and full-featured watch, all in a 200m (660ft) water-resistant housing.

Let's start with the feature list:

• Stainless steel case with rubber side guards.
• Integrated rubber strap with machined buckle and clever strap retainer. It's also long enough to easily go over a 1cm wetsuit.
• Swiss-made depth sensor.
• Dive mode which starts automatically by the pressure sensor on the left side (more on this below). In dive mode, it logs the min and max depths for each dive.
• Always-visible temperature sensor, in Celsius or Fahrenheit.
• Film supertwist nematic LCD. These are the ones with a brilliant green hue from certain angles which makes it very readable.
• Electroluminescent backlight for the entire display.
• Battery life indicator. Around the outside of the dial from about 5:30 to 9:30, there is a 11-bar battery "gas gauge" that shows remaining battery life. In a safety-critical item like a dive computer, this is a great feature.
• In dive mode, the backlight comes on automatically when you tilt your wrist, as do many Casio G-shock watches. Nice touch.
• The dive log records a total of 50 dives, with log date & time, max depth, min depth, and temperature at each recorded data point.
• Sleep mode. You can have the display turn itself off after a configurable interval, to be instantly activated on any button press. Also an excellent idea, especially for a watch that you may only break out a few times a year.
• Fast ascent warning. An alarm warns you that you are surfacing too rapidly and are risking the bends.

There is also a full complement of digital watch features:
