The CanDo Massage Gun is the ultimate in handheld massagers. Cordless, this unit powerfully delivers percussion massages (repeated, rapid striking of the body as a massage technique) to relieve muscle cramps and trigger points, ease knots and reduce sore and achy muscles. Additionally, this unit is extremely effective in promoting better circulation, optimizing mobility and reducing stress and tension. Three operational modes are available to choose from offering different types of relief - Fitness Mode, Medical Mode and Health Care Mode. Fitness offers the highest speed and torque, offering six levels from 1,200 RPMs to 3,200 RPMs. Those actively involved in fitness and athletics on a regular basis will find this mode to be their favorite. Medical is designed for point-to-point local treatment. Suitable for physical therapy, the pressure and speed increase gradually from 1,000 RPMs to 1,900 RPMs and then back within 6 seconds. This pattern then continues automatically. Health Care offers the lowest RPM and torque as compared to the other modes. With a soft touch, this mode is perfect for daily health care use at home. The six levels range from 1,000 RPMs to 2,000 RPMs. This will be the go-to mode for those looking to massage away daily stress and tension. Six interchangeable massage heads are also included. Multi-functional is the name of the game when you consider the options for mode, speed and which massage head to use. The CanDo Massage Gun is a versatile unit offering customized, handheld massages. Please note, it is advised to use the device only on muscle groups and avoid using it on your head, over bones or sensitive tendons. Depending on usage of the unit, the included rechargeable lithium-ion battery provides up to 6-8 hours of massage per charge. Don't let the Massage Gun's weight, at less than 5 lbs., fool you. This is a durable and sturdy device that will quickly become a family favorite. Easy to use plus and minus buttons allow users to quickly increase and decrease the RPM speed of the massager. The included sturdy and padded carrying case make storing and travelling with the unit a breeze. The six interchangeable massage heads include air, fork, flat, bullet, round and wedge.
