The Ultra-Lite uses Navcom, the same material used on the Sims Limbsavers. The Ultra Lite uses three carbon rods to hold the Navcom components. They are adjustable both by weight and by position therefore allowing you to not only eliminate all forms of vibration but also achieve perfect balance. This is all done with 1/3 of the weight of a normal stabilizer. The smaller ones make excellent weight compensates for v-bars and counter balances. Color: black.
