For Christmas I used the money the family gave me to buy myself a HOG D1 1st mated to 2 HOG seconds. I got a great deal from Tech diving unlimited. The hoses that come in the package for the seconds are 25" and 7' long. I am sure a 7' hose has some kind of technical diving application but only wearing technical gear but not being a technical diver, I don't understand this. Can some of you old salts or young salts for that matter edumacate me on the purpose of such a long hose? It seems like it would get tangled and be in the way a lot. Thanks fellow scuba boarders!
