If you frolf at any course with a pond this will come in handy. It floats so it is slightly easier to retrieve than a normal disc when it lands in a pond or lake. If however there is much current, like in a strong river you can kiss your disc good bye, it will float alright, right down the river.
It does seem slightly harder to control than some drivers like the beast and the Valkyrie so I am not sure if it actually causes me to throw it into the pond more frequently, but if it does at least I can get it back. 4 stars
