is there a way to attach it to my buoy?
Jeremy L Yes I think you could do that. There is a little hole through the end where you could loop some line through and tie to something else.
MAAKA M Rope it. Picture doesn't show it but there is a hole at the end.
MONTHAKAN R I have not used mine, but there is a hole at the top that you can probably use for attaching it to your BC somewhere.
JOANN B Yes, there is a loop at the end of the whistle where you can put a ring and hook it to wherever you have room. I keep mine attached to my BCD strap.
JEREMY T Yes. Mine came with a small string that I could attach to a BCD or anything else.
SEAN S yes, i attached it to my BCD
