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.
