Can this be used with a Cressi Junior Dry Snorkel?
PAUL W I find that it is too big for smaller diameter snorkels.
JEFFREY B If the Junior Dry is a standard diameter I would say yes it would. As depicted in the picture the clip is split and you just open up the clip and put the snorkel tube in the circle. I was careful when I did it so I wouldn't break the clip. The two sides of the lock kit are attached with velcro. You just run the mask strap through the rectangular clip side and the circle around the tube. The velcro attachment is pretty cool because you can adjust the angle of the snorkel as needed.
PHILLIP B In addition to having a smaller mouthpiece, the Cressi Junior Dry Snorkel has a smaller bore (tube diameter) than other snorkels, and for this reason, the Oceanic Snorkel Lock would likely fit too loosely on this model.
