The patented integral laser module is an optional item that can be added to make the 100 a full-featured tachometer. The Nova-Pro 300 has all the features of the 100 and includes the patented integral laser module for tachometer mode or strobe trigger mode plus adds a high-contrast inverse blue LCD with backlight and touch-sensitive number pad for setting flash rates quickly. Other features include ultra-high intensity LEDs for more light output, memory for up to 10 preset flash rates, input/output jacks for external sensors or pulse repeater output, and NIST Traceable Certificate.
