RE: How often?
I am still shooting the same Flecthhunter I bought in 1990 or so. I have bought several others and tried them, but the old release still works wonderful, and has a host a features I love. I bought several as a backup in case I dropped one in the woods or from my stand. I always pack two in the woods for those just in case type situations. I do oil my release often which is the only regular maintance I do on it and it has not let me down in all the years I have owned and shot it. It does show a lot of wear, but not enough to retire it.......yet.
