Whether you’re freediving or spearfishing, a dive computer can help you make the most of your experience. It can tell you when you’re going too deep, how long it will take to reach the surface and when you’ve reached your maximum depth. In addition, a dive computer can help you estimate the depth of the next dive.
Some dive computers combine depth gauges and a timer to calculate the amount of time a diver will be underwater. These devices can also display the air in a tank. Most computers warn divers with an audible or visual alarm.
A dive computer can be purchased as a standalone device or as part of a dive watch. All major manufacturers have models that can download dive data to your computer. This allows you to view your entire dive in a profile. This is important because it provides additional information not normally available through a dive computer.
Computers can be either wrist or console mounted. Wrist computers are smaller and use a small screen. Console computers are larger and require a connection to your regulator. These computers are generally easier to read.
The type of dive computer you choose will depend on your needs. You’ll want to consider the features, the price and the frequency of use. If you’re planning to use the dive computer frequently, you may want to consider purchasing a model with a quick disconnect.
If you’re looking for a more economical dive computer, you may want to consider buying used. Dive computers come in a variety of shapes and sizes. You may be able to find a used model for a fraction of the cost of a new one.
