A good tube of bow string wax and regular applications to the string and serving will prolong the life of any bow string. This however does not remove the need to replace the string and or cables on a regular basis. Many manufacturers recommend replacement of the bow string annually. If you are a competitive shooter or think you probably shoot considerably more then the average hunter, this may be more often than once a year.
Strings used to show signs of wear in the form of discoloration or fraying, letting the shooter know it was time to change them. The synthetics strings are made of today though may weaken and show no signs of wear and tear. Strings that do not get a regular waxing, will begin to wear and weaken under the serving, due to vibration between the serving and string during use. Again regular waxing will help keep the string from moving under the serving prolonging the life of the string. Other areas of wear would be under knocking points or a knocking loop if installed. The wear in these areas often goes unnoticed because they are covered. If you use a release that directly attaches to the string, this is a high use area and usually the first place to show wear.
The summer months are usually when most hunters begin shooting and tuning their bows. This is also a good time to head over to the local pro shop and get the cables checked and the string replaced. Once season rolls around the last thing you want is to find a worn string needs replaced and then set up the bow again or worse yet, having a bow explode in your face damaging your equipment or you.
Bottom line, If you don't remember having the string replaced last season, go have it done now and make it a regular practice if you already don't.
