Scubapro Aladin 100 Wrist Dive Computer

The dive screen has four clearly labeled quadrants: Depth, Time, No-Stop Time (NST) and a fourth toggle field that can show temperature, max depth, MB level, O2%, timer or clock. During a safety stop the toggle field shifts to a countdown based on your settings. If NST is passed and the dive requires decompression, the display adds Deco Stop and Total Ascent Time information.

Yes. The Aladin 100 has Bluetooth and syncs dive logs and dive settings wirelessly with the SCUBAPRO LogTRAK 2.0 app. You can also use LogTRAK to change the computer's name.

No. The Aladin 100 is a single-gas computer with no air integration and no built-in compass. It has Scuba and Gauge modes, works with Nitrox from 21% to 50% O2 and has a maximum operating depth of 80 m / 260 ft.

The Aladin 100 uses one user-changeable AA battery and ships with a pre-installed Varta Industrial Pro AA. SCUBAPRO rates battery life at more than 300 hours with the backlight on. The battery chamber is waterproof and sealed off from the internal electronics. See the user manual for the battery change procedure.

Yes. The Aladin 100 powers on automatically when underwater.

A dive computer tracks the actual depth and time profile you have dived and the tissue loading that follows from it, which is personal to you. A rented computer has no record of your recent diving, and swapping models each trip means relearning the display and menus when you should be focused on the dive. Owning one you know well is a genuine safety and comfort improvement.

No. A computer only tracks the profile of the diver actually wearing it, and even buddies who stay together do not follow identical depth and time profiles. Every diver needs their own computer, and passing one between divers or between dives is unsafe.

Conservatism settings make the computer's calculations more cautious, shortening allowed bottom times and adding margin beyond the base algorithm. Divers commonly add conservatism for factors such as cold, hard work, fatigue, or repetitive multi-day diving. How and when to adjust it is covered by your training and your computer's manual, so set it before you get in the water and follow what your computer tells you during the dive.

Yes, both change the picture, and both are governed by your training agency's guidance and your computer's instructions rather than any casual rule of thumb. Many computers have an altitude setting that must be configured before diving at elevation, and most display a no-fly or surface-interval countdown after a dive. Follow your computer and your training, and ask a dive professional or a dive-medicine specialist if you are unsure.

Rinse it in fresh water after every dive day, paying attention to the buttons and around any sensor openings where salt crystals form, and let it dry fully before storing. Keep it out of prolonged direct sun and extreme heat, and avoid pressing buttons while sand is on the case. Inspect the strap or bungee often, because a failed strap loses far more computers than a failed computer does.

A wrist computer is worn like a watch and read by raising your arm, while a console computer sits at the end of a hose with your other gauges. Air integration means the computer also displays cylinder pressure, either through a hose or from a wireless transmitter on the first stage, and often estimates remaining gas time. All of them run a decompression algorithm, so the real difference is where you read the information and how much of it you get.
