The Echo Pro is an injection molded design, as opposed to the original handmade echo carrier, this is how we can offer it for a lower price point. Since it’s injection-molded, the Echo Pro has higher precision, such as a more angled channel, as well as a newer design. This includes longer spacing on the quick clip retention holes, and a closed bottom, with a slot to accommodate potential future hardware attachments. It also ONLY comes in black as opposed to the many other colors of the original Echo carrier.
