The most important thing about the dive computer, in my opinion, is how it determines the value of the set point, or marks and the target number for each dive. If you are new to diving, then you will know that the set point is the maximum depth at which a certain object can be explored and the target number is the number of feet that must be surveyed for any kind of fish participation. I personally think the values should change slightly because some objects are more dangerous to explore than others and some sets of dives could be easier and safer than others. Some divers also like to set the mark chase because they like to be able to see if another diver has gone too far away, although this is not always the case.
One of the nice features on the 6m Check is the ability to set the distance to the maximum depth at which the camera will send out the dive computer commands. This means that you have a good piece of equipment that can help you conserve the oxygen and energy in deep water and when you are diving deep the currents are much stronger and there is less for you to do to conserve your diving time and energy. This feature is very handy, especially if you are using different types of scuba equipment and you need to keep track of the depth and the current limited cells for each dive.
In addition, the setting of the mark chase allows you to see what the top current is. The first thing that we notice while scuba diving is the bottom current, we call it the back current and this is the line of defense and safety for a scuba diver. It is important to know what the top current is because this will tell you what direction you need to go to avoid getting hit by the nose dive bomb. Most novice divers don’t know this, but the best way to get around someone or something in shallow water is to move up and move left, not right. This is where the 6m Check comes in handy because it will tell you the current limited cells. The Mark Chase is another feature that will allow you to conserve oxygen and dive safely, which is why it has been used by military personnel for years as a way to mark their diving hot spots, military bases, rescue sites, and anything else deep enough to be dangerous to navigate into without an extra depth charge.
