I would say many factors contribute to how long the latex will last on a mouth call. One is the amount of time spent in your mouth. Another is how you treat it while it is out of your mouth after being used, if you clean it and store it in a cool place it will last longer than leaving all that bacteria on it to eat away at the elasticity while in a warm/hot place. The quality of the latex is a factor as well. I always carry a few spares on visually inspect them before heading into the hills with one. If you are a 'true' ******* and have tobacco in your lip, I assume the life expectancy would be much shorter(that is for HOGAN).JuddCT said:My question is how often does everyone buy a new mouth reed elk call? Is there a time limit that I was too dumb and overlooked or is there just a known amount of time? Thanks for the info.
