The latest disc design and the worlds first brass disc with holes. After the huge success of the Pro soft sonic disc we were inspired to make a disc with holes in it, to add a little bit of weight to it, and the result is the Pro Ultra Sonic disc. Since discs have no effect below 7 mm we decided to start the diameters at 7 mm increasing in 2 mm up to 11 mm.
The Pro Ultra Sonic Disc shape is optimized to add the desired effect, but still very easy to lift of the water due to the venting holes, while maintain the capability to create a vortex behind the disc, allowing soft modern materials to swim freely instead of collapsing in hard current.
This is the future of modern fly design without a doubt!!
