In order to make clear dot projection at close distance, not the same as manual dot projecting tool or a laser pointer, it makes even better job with a 515nm 5mW green laser diode module. It gets constant power source supply and good use of cooling system. Within constant dot projection of 8 to 10 hours, it maintains highly stable performance and highly clear forest green dot projection in continuous use.

When users are looking for a high speed and easy operating line aligning tool, it is operating easy with a highly intense beam device of 445nm blue laser line generator. In various industrial and high tech line positioning work fields, owing to its special use of import 445nm blue laser diode and metal heat sink cooling system, after configuration with metal housing tube, this blue laser module gets good thermal emitting, and increasing stability blue line alignment within 8 to 10 hours.
