does anyone have this portable fish finder? Ive been having a little bit of trouble at times getting it to read even while in the water it does not show the depth. Also does anyone know the proper depth you should have the sensor below the float and how do you mount or troll with it?

One more thing. when it reads fish is that directly below the sensor?

also i have been having a few problems which i thought maybe you could help me on. you know when you first turn on the fish finder it has 3 dashes by the FT? Well when this is in the water this happens to me and i just have to restart it all. does this do it to you any? I didnt know if i had to wait for it to read or mines messed up, because sometimes itll have lets say 6'5" on there and then it goes to the 3 dashes. do you know why it does that? thanks!
