Not a problem, I have to believe, if you constantly shoot your bow every day for an hour or two, the your string will stretch or become weak, fiquretively speaking, then yes, I would change them out yearly, if not semi-yearly.
Frequency has everything to do with it.
Strings can last many years. I change mine every other year (or so). Whether it needs it or not.
The serving I change with a lot more frequency. Usually at least once during the summer warm ups and I put a fresh serving and nock set on before the season begins but, I shoot a whole bunch of arrows.
It's a good idea to keep plenty of wax on the strings. They will weather the punishment better.
Bow serving and string, no stretch low creep material, is designed to perform with minimal maintenance.
Life of a bow string will be different for every bow. Type of cams, number of strands, draw weight, draw length, and most of all usage are all factors to consider when determining frequency of string maintenance.
Simple, Archers need to pay attention to creep, which when compared to stretch - creep is non-recoverable elongation, when stretch is the basic elasticity of the string material which is recoverable. In short, creep will cause your bow to fall out of tune, excessive peep rotation, draw weight to increase, and draw length to extend.
So for starters, pay attention to the sound of your bow, wear around the cams, possible caliper release abrasion, high strings which is sign of string breakage under the serving, along with creep...
If you experience any of these problems, change your string, otherwise you're just blowing hard earned money at the local pro shop!
O" and Wax the Full Monty... It'll help keep the strands together "bundle", Lubricate the fibers to prevent fiber to fiber abrasion, and help prevent water absorption... Now I'll stop wasting everybody's time and attend to my fiance
The record books, that are put out by Boone & Crocket and Pope & Young and where I live is Henry Kelsey they are a great way to research a state or a province for big game. This does take some time but the knowledge it gives you, can be very valuable. Not all hunters have their trophies recorded, as where I live after the Hanson Buck became the new world record typical Whitetail, we saw a flood of hunters and now that has happened, some hunters are shying away from the record books but...
