• CHECK STRINGING TENSION WITH CONFIDENCE: Electronic tension calibrator helps verify racket stringing pull readings during tennis, badminton, squash, and racquetball service work; best used for repeated checks and average readings because string tension can shift during measurement.
• LCD DISPLAY WITH 4 UNIT MODES: Clear digital screen shows readings quickly, and the UNIT button cycles through kg, lb, catty, and oz for different workshop habits; ideal for stringing machines, racket shops, coaches, and DIY stringing setups.
• USE THE LIFTING RING FOR BEST RESULTS: Hold or connect from the lifting ring side when weighing or checking tension; do not grip the body shell during measurement, as side pressure on the housing can create larger reading error.
• DURABLE ABS HANDHELD BODY: Black ABS engineering plastic shell is lightweight, firm, and easy to carry in a tool bag; approx. 4.7 oz body weight makes it practical for bench use, travel stringing, club maintenance, and quick tension checks.
• BATTERY CARE AND PACKAGE NOTE: Requires 2 AAA 1.5V batteries, not included; replace batteries when the low power sign appears and remove batteries before long storage. New and old appearance versions may ship randomly, with the same core function.
