The ones we use we make ourselves, we use a dowl of approx 35mm cut the face at 45 deg, taper slightly towards the back. Drill the back out to about 8mm to about half way, put the wire in and then pour lead in the back to give a bit of weight. then retrieve it fast so that it works like a popper on the top of the water, do not pull too fast so that it jumps out of the water, with trial and error you should go tight in no time. I nearly forgot, we paint them white, some we give a red head as well. Hope this helps.
