hey guys, i really need your help on this one.
i recently started using a fish finder, and i think i like it, but i think im not getting the most out of it.
first question: this one time, when i had the fish ID symbol turned on, there were lots of fish, but when i turned off the fish ID symbol (to switch it to fish arcs) there was nothing. whats the deal with this?
another thing i dont quite understand is how the dang thing works.
lets say i am sitting perfectly still, not drifting one bit, and im over a sunken tree or a log or a fish or soemthing. what will this look like on the screen?
earlier today we were drifting but not very fast at all, and there would be a stump on the ground and it would show up and then be gone, but we hadnt moved. whats up with that? how come the stationary stuff (trees, stumps, rocks) disappears when neither the cover or me is moving?
thanks for your help guys...im a total noob at fish finders.
