Suggestion for other new divers. An inexpensive way to keep your octo from dragging and available. I was taught the pretty way of out of air or low air techniques like everyone is, but was told that in reality the person is probably going to take the reg from your mouth (they know it works, they see the bubbles!). So, using thing bungie cords and zip ties (I learned this trick from my instructor) I make a necklace. Make the main part large enough to fit over your head without choking or causing entanglement issues. I did this by cutting the bungie and zip tieing another part to it. Then, at the bottom, take a 2-3 inch bungie portion and zip tie it on. This creates an elastic pocket that the octo mouthpiece fits in. The best part is, it is easy to remove if someone does the "proper" way of signaling. But if they don't, the octo is just below your mouth so you can use it prior to grabbing the culprit and beginning your ascent.
