Review: Easy - The product seems to be really easy to use. Im not sure its entirely accurate it seemed to give a few false results in shallow water 2ftish where i could see the bottom but other than that no issues at all. I think i should mention if like me you are casting out with it use a heavy line. I used 12lb casting to about 60yrds and managed to snap line.
