Yes, but, there is the but ----. I lost my necklace once (and later found it in my bag) but was in a dive shop that had the Dive Rite necklace so grabbed one until I could tie up another. Then I decided I rather like the little triangular shaped plastic sleeves that only need an overhand knot and are more compact in use. Yeppers, make your own with the fisherman slip knots and a piece of bungee material. Oh, and the Dive Rite necklaces come in colors like pink and blue in addition to Darth Vader black
