Artem Pochtarev from Ukraine testing a prototype of the stringster app with his freshly strung BABOLAT rackets. Like most professional players Artem had his racket strung without “pre-stretch” to avoid unnecessary wear out of his strings.
Those who have their rackets strung with pre-stretch will find out that the stringster app initially shows a slightly higher measurement result than they would expect. This is ok and doesnʼt mean that the stringer did a bad job!
