...the four cornerstones of the new Martin RGB Laser 1.6 On this foundation Martin has applied innovation and a spectrum of colors into a compact and light weight laser unit. With simple plug-and-play operations, hundreds of pre-installed effects and a cooling system that eliminates the need for expensive and bulky water cooling, the RGBL 1.6 is all about performance made easy. Slightly larger than an average DVD player, yet able to take the knocks and blows of touring without misaligning, the RGBL 1.6 is designed for the road.
