What makes a good job to get ideal dot alignment accuracy for tire repair and retreading dot positioning works? Not relying a simple laser pointer, it is a better substitute to apply a Berlinlasers 515nm green laser diode module. Employed by an import 515nm green laser diode and a qualified glass coated lens inside a durable metal housing tube, only after its easy connects with DC power supply, it allows for long operating time lasted green light and green reference dot projection, no light decay, blur or dim in continuous use.

Basically laser diode module adopts ultra compact size design, allowing for convenient and easy installation or integration into any tire repair machine or device. It is always marking the center of damage during grinding, patching, and bonding of old tires for precise repair and improved retreading quality.
