Why Tennishead Inc.?
Manual stringing machines are relatively inexpensive but are inaccurate, slow, and inconsistent. Once a user masters the stringing techniques, they are ready to make the jump to an electronic one.
An Electronic Tension Head could be an affordable option for a bit over $600. However a full Electronic Tennis Stringing Machine like the Prince P7000 could cost around $4700.
