There are expensive systems out there ; very very expensive military systems, so a quarter of a million pounds plus. And we sit somewhere in between that. Our price point is around about 75,000 pounds( GBP) for a complete system solution, you can hook the trailer up to your 4x4 vehicle and you can drive anywhere you want and get it in the air within a few minutes, and move around to different locations while staying in the air. Or you can come back down to box it up and move to a different location. So it's quite flexible as a system, quite adaptable to the mission scenario and at a good price point that makes it affordable to blue-light services as well as companies that want security.
