K-LaserThe Eltech K-Laser is the device that made the name K-Laser famous as the premier laser in the Protobiomodulation world. For many years, K-LaserUSA built their reputation on delivering these top-quality Italian-made masterpieces. Then in 2018, K-laserUSA made a huge mistake and lost their exclusive contract to sell the legend and is now selling just another laser from China. Luckily Chattanooga picked up the exclusive contract to sell the original . The K-Laser Cube series are Italian built class 4 therapeutic laser devices that offer 3 or 4 different wavelengths simultaneously or independently. The Cube is an incredibly well designed piece of equipment that is already used all over the world.

In addition to being the highest quality laser you can buy, this system includes the widest range of accessories of any class 4 system. With their proprietary interchangeable heads, you can focus the beam from 15mm ( for acupuncture and trigger point) to 40mm with their large head, you can also do unattended therapy with their extension plus kit. No other class 4 does acupuncture, standard therapy and unattended therapy.

The Cube is also one-of-kind system because they allow up to 12 phases in one therapy protocol . This means that selecting a single protocol from the internal protocol library can execute even the most advanced combination of CW and pulsing in any any wavelength. The means that a single protocol can start out in continuous wave mode with all 3 or 4 wavelengths on for 30 seconds follow by 5 HZ pulsing at 810nm for another 40 second followed by 10 other specific setups. No one else in the industry has this level of control.

This WiFi enabled system also allow for patients tracking. As a option, doctors can enter patient parameters and track their treatments dosage and other parameters using the laser.
