Why you need a diving computer

When you first start diving, a lot of the information that you need to know is given to you by your diving instructor. However, as you become more experienced, you will want to start relying on yourself more, and using a diving computer can help you do that.

A diving computer is an essential piece of dive equipment that allows you to track your depth, time, and decompression status while diving. It takes all the guesswork out of dive planning and helps you to stay safe underwater.

If you are new to diving, then it is best to start off with a basic model of a dive computer. Once you have gained some experience, you can then upgrade to a more advanced model.

How to use a dive computer

Dive computers can be a great tool for helping you to plan and execute your dives, but they can also be a bit daunting if you’re not used to using one. Here are a few tips on how to get the most out of your dive computer, whether you’re a beginner or an experienced diver.

1. Read the manual! This may seem like an obvious one, but it’s important to actually sit down and read through the manual that comes with your dive computer. It will help you understand all the features and functions of the device, and how to properly use it.

2. Plan your dives in advance. Once you know how to use your dive computer, take some time before each dive to input all the relevant information into the device. This includes things like your dive site, depth, bottom time, and other factors that will affect your dive.

3. Use the safety stop feature. Most dive computers have a safety stop feature that allows you to add an extra stop into your dive plan in case of emergencies. If you’re new to diving, or if you’re diving in unfamiliar waters, it’s always a good idea to use this feature.
