This video by Rush Bragg as mentioned in the Facebook discussion shows you how to prepare a Pro Series Flyboard for “professional” use.  As contrast, keep in mind that all Jetblades and X-Jetpacks come out of the box ready for professional use and are designed with the rigors of real world use in mind.  Jetblade inserts are CNC machined 316 stainless steel from our first model on-wards, with a 100% service rating, meaning zero inserts have ever failed.  One more note, all of the modifications shown in the video, as well as any professional use, most likely immediately void the warranty on the Flyboard as it is intended for leisure use only.
