The Transmitter Band 3-Pack from MagMod provides a simple yet brilliant way to attach radio transmitters to your hot-shoe flash units. It does not require messy Velcro or sticky adhesives, making it one of the most comfortable and easy to use flash modification accessories available in the market today. Stretch the large opening of the band and attach it to the flash unit. Each transmitter band included in the kit is made from an elastic silicone rubber that retains 99% of its elasticity over time. As it maintains its elasticity, the bands will never lose their grip and you are assured that all transmitters will be secured to the hot-shoe flash units.
