halemanō;5696593:I think the "average" Navigation Specialty involves more "learning/teaching" than any other "average" PADI Specialty. I feel the same way for "good" versions of PADI specialties as well.
+1. I think the Nav specialty has a lot to offer, both in terms of useful information AND something that can have a diver revel in a real sense of accomplishment.
