Anglers Image Super Float was designed to float large dry flies and strike indicators higher than any other liquid floatant. It is all-natural, water insoluble, environmentally friendly, and non-toxic. Super Float can be applied to the fly just prior to casting but one neat trick is to apply it to your fly at the fly tying bench. Because it is long lasting, evaporates very little, and does not leave an oily residue, your flies and indicators can be pre-treated with it prior to fishing. Super Float is also thermally stable meaning that it will not harden in cold weather or become too thin in hot temperatures. The unique upside down hanging bottle attaches to a zinger or D-ring for easy dispensing.
