G4 SSL BAT Compression Testers

The Purpose of a Bat Tester

The portable barrel compression fixtures or bat testers were developed for the softball and baseball industry to measure the barrel stiffness of a bat. The barrel compression of a bat correlates to its performance. Generally, bat performance increases as barrel compression decreases. Bats having the same compression, but different model numbers, may have different performance, however. 

The bat compression tester is completely portable and does not require power.


The bat testers are used to determine when a bat has exceeded its intended life and can reveal when bat has been tampered with (i.e. when a bat has been rolled or when the barrel has been shaved).  The tester can be used to test bats before games and tournaments to help ensure fair competition.
