1. Learning About the Diving Spot is vital to Improve Your Underwater Navigation

Learning about the diving spot is, probably, the most obvious of these seven underwater navigation tips. The more you know about the place where you are going to scuba dive, the better. So, look for someone who has dived there before such as a nearby dive center, local divers, an instructor, etc.


2. Before using your underwater GPS: Remember That Diving Navigation Begins on The Surface

Try to get a map and use an underwater compass to get an idea of the direction you’re going to take. So, you will be able to draw a preliminary route.

Natural navigation begins before you jump into the water. Remember where the open sea is, and where the coast is. The light is another great reference, thanks to it, we know where the surface is. Moreover, if we pay attention to the sun´s position before descending, we will be able to get better navigation results. If you move towards the sun at the beginning of the dive, you should have the sun on your back when you return.


3. Use The Environment as an Underwater Navigation System

To begin with, if you are diving from a boat, using the mooring as a reference will help.

One of the best natural underwater navigation tips we can offer you is to mark a reference line as a way forward. In other words, look at a sandy path or take the edge of the reef as a reference point. Some people focus on a depth contour on the coral walls and explore them at a fixed depth.

Other key reference points are natural and human-made terrain features. Striking rock formations, pinnacles, points that are eye-catching, or stand out from the rest of the background as an anchor, etc., will help you as an underwater GPS to find the correct way back home.

As you go forward, remember to look back. So, you will be able to recognize the way back.

4. Take Depth References Continuously to Improve Your Submarine Navigation

Taking depth references is another of the most important underwater navigation tips. Your dive computer will be very useful for this task, especially, at the key spots of the dive.

If you are practicing diving navigation close to the sea bed, you will know if you are approaching the coast when the depth decreases. However, If the depth indicated by your computer increases, it is a sign that you are going forward to the blue.


5. Underwater Navigation Scuba Is About Estimating the Distances Properly

The easiest way to do this is to consult your watch. If you know that you need 40 seconds to swim 20 meters/ 65 feet, you can calculate the distance you cover as you go.

Don’t forget to check your tank pressure. If you know your average consumption, you remain at approximately the same depth, and your activity level is constant, your breathing rate will be uniform, and you will be able to calculate the distance concerning your air consumption.

In any case, Following the three-thirds rule is always a good idea. Use 1/3 gas to go, 1/3 to return, and 1/3 as a precaution.


6. Be Very Aware of The Currents to a Proper UW Navigation

Taking into account drifts is another of the most fundamental underwater navigation tips. As you know, going with the flow does not require physical exertion. However, it is very hard to move against it. Therefore, the first thing you will have to do is to ensure the water current is not too strong. After that, start the dive against it. Use underwater morphology as a defense against the flow, and enjoy drift diving during the return.

7. Learn How to Use a Dive Compass

As we told you in the article The Importance Of The Compass In Diving, the Underwater compass is a fundamental tool for orienting ourselves while diving and returning to our starting point. We use this tool to locate our current situation and follow a course previously set.

If you want to know the parts of a compass, its history, and the factors to take into account when using it correctly, do not miss this post. If on the contrary, you do not know how to use it yet… It’s time for the last of the underwater navigation tips: Take the course to become a PADI Advanced Openwater Diver and choose the specialty Underwater Navigation with Dressel Divers.

During three scuba dives, you’ll practice:

  • Methods to estimate distance underwater.
  • Compass navigation while making at least five turns.
  • Marking or relocating a submerged object or position from the surface.
  • Underwater map making.
