Isn’t it cool how scuba divers look when they are going scuba diving. Their sleek look makes you want to be a scuba diver who dives into the sea for a living or recreational purposes. However, there is some bit of science that is associated with diving. Science is one of the things that keep divers alive when they dive into war. The human body has a limit to the pressure the body can manage. Without adequate data about the water pressure, the human body can lose air, nitrox and be severely damaged.
Perhaps the essential part of diving can tell the water pressure. This would, in turn, inform the diver how safe continuing diving is. Knowing the water pressure is vital for the best dive experience technology has made it easy for divers to tell how safe the water pressure is. The technology in question is the dive computer. There are different types of dive computers, and in this post, we would give you a list of the best dive computers

Q. What is a dive computer?
A dive computer is a form of safety technology and a vital part of your scuba kit. It is a diving-assisted technology that provides accurate time diving data you need to execute a safe dive. When a person dives too deep, there can be severe damage to the body. The dive computer prevents this by calculating the dive depth and the time spent during diving to find the time to continue to dive safely.
Q: How to use a dive computer?
You use a dive computer by correctly reading the data provided in big digits on the dive computer screen. These data are:
No Stop Limits
The no stop limits allow you to make stops for air decompression when you are swimming up and the amount of time you need to stop.
This is the total estimation of the amount of time you have been diving
The Dive Depth
Your depth level in the water
Your dive history allows you to track your diving periods so you can safely engage in other activities before and after diving.
This data is concerned with how fast your swimming up to the surface. You would be altered for an emergency decompression stop when you have ascended wrongly.
There is a readout on the watch that tells you your battery level.
Not all dive computers come with a compass, but they are good to help you with a sense of direction when diving
Q: When using a dive computer, i should ascend (go up) at a rate not faster than?
When you ascend at speed greater than 30ft per second, you have ascended wrongly and too fast. Any of the best watches we have provided in this list will alert you when you have ascended incorrectly
