The NEW SAM Extreme tennis balls are a must for anyone who coaches tennis or has a ball machine. SAM have developed the Extreme range of pressureless tennis balls with a wool blend cover that will endure long hours of top speed tennis.

Tested at speeds of over 210km/hr the SAM Extreme balls outlasted pressurised balls by an average of 5 times. This means these pressureless balls represent excellent value for money. The bucket comes with a convenient SAM Target on the back, so you can empty the bucket of balls into your Coaching basket, or your ball machine and then place the bucket somewhere on your court for target practice.

Please note, this tennis ball is only suitable for use with a SAM Ball Machine (other ball machines use different wheels which don't combine well with this ball).
