Dive Computer

A dive computer is an important piece of equipment worn while diving. The device is used to measure depth and length of dive to determine a safe ascent time. It helps to avoid decompression sickness, which can occur when a diver ascend to the top too quickly while diving. The dive computer constantly calculates and displays dive times and decompression stops eliminating the need for a separate depth gauge.

All dive computers come with a few key features standard with all the devices. When choosing the dive computer for your dive, you'll need to find one that is easy to read underwater. It should have a low battery warning so that the battery can be changed before a dive. The dive computer needs to run for 24 hours at least so it can continue to display dissolved nitrogen long after the dive has been completed.

There are some features that are optional but can enhance your Bahamas diving experience. Most dive computers can double as dive watches making them extremely efficient. Aside from the battery alarm, some dive computers have an alarm that will alert the diver if he or she is ascending too quickly. This might be a great feature for divers that are new to diving and need that audible reminder to watch their ascent time.

Most divers want to keep a record of their dives for future reference. Some dive computers can upload and save their data directly to a computer. This can make tracking and logging dives quick and simple.

It's never a good idea to share dive computers with other divers. The dive computer tracks more than one dive. It will compute changing gas levels for the individual based on their dive. If a diver uses someone else's computer, it throws off the calculations.

Beginners who have no idea what they want or need can ask their Bahamas diving instructor. The instructor can advise them on non-essential features and whether they personally could benefit from any of them. It will come down to a personal preference, and how much the beginner can afford to spend on equipment and non-essential features.
