Dynamic Perception Stage One Motorized Slider. High precision built slider, lightweight and very portable. Great for Time lapse photography. Unlike most sliders that have to be purchased as a set length, the Stage One slider can be broken down to 21" sections that will allow you to fit the equipment into standard Airline Carry-on sized luggage when traveling. Comes with the base tubes and two extension tubes for a 42 inch total track, the high precision carriage and motor kit, the MX2 Dolly Engine controller and power supply. Originally paid over $800 for this kit. https://vimeo.com/44217237?fl=pl&fe=vl
