PADI Underwater Navigator Spezialkurs — Marsa Alam

There are two kinds of diver: the one who surfaces and looks around to find the boat, and the one who surfaces next to it. The Underwater Navigator specialty is the difference, and it is a smaller difference than most divers expect — three dives.

The first dive is about natural navigation, which is what good guides actually use: reading the slope of the reef, the direction of ripples in the sand, where the light is, which way the current was running when you dropped in. You learn to build a mental map as you go rather than trying to reconstruct one afterwards.

The second dive brings in the compass properly — not just holding it and swimming, but reciprocal headings, kick-cycle and timed distance estimation, and how to keep a heading while a current pushes you sideways. You find out how far off you are, and then how to stop being off.

The third dive puts it together into patterns — squares and triangles run blind, then a navigation exercise where you locate a specific object and return to your starting point. By the end you can plan a dive as a route rather than a direction.

The Marsa Alam coast makes this unusually worthwhile. Much of the diving here is from shore or from small boats onto large bays and long reef systems, where knowing your way back matters far more than it does on a short mooring-to-mooring dive.

Prerequisites: PADI Open Water Diver or equivalent, minimum age 10. Counts toward the PADI Advanced Open Water Diver certification as an adventure dive, and toward Master Scuba Diver.
