I use the black Minelab hip mount bag. It hangs fairly awkwardly and the head phone jack makes it hard to close the top. I secured the coil cord with a velcro cable keeper ( from a camera store) to the strap clip to protect the cable connection. If it starts to rain I can pull my coat over the bag as it does not protect it enough otherwise. Army surplus sell "dump bags" that others use, but they have pockets and zippers that might get bulky.
