Other odours that scent can help mask are diesel, perfumes or cologne, etc. Did your eyes just pop open wide? Perfume or cologne on a fishing trip? Who wears perfume or cologne on a fishing trip? You will be surprise as some people do. I have gone fishing with an angler who did just that. He not only applies cologne before meeting up (at the jetty). He also carries the bottle of cologne with him on the boat. He uses it off and on while out at sea. Well, some people are just like that.
