The Neon 21 tension head is the electronic tension head, which makes stringing much faster and easier:

• It has the microcontroller chip to control and monitor the tension; it provides 1 pound tension accuracy
• Easy to calibrate the electronic tension head.
• The two-way DC motor to pull and release the string. You do not have to use muscle to operate. You just need to push the button to pull and release the string.
• The voltage deviation of the local AC power line has no affection on every tension pull.
• Fuse protection
• LED tension readout to display the tension setting
• Pound/kilogram selection switch to select the pound or kilogram operation
• Precise tension on every pull
• All-metal diamond-coated string gripper
• 1 years warranty on the electronic tension head
• The characteristics of the electronic tension head are constant pull and precise tension on every pull.
