That's kinda my point though. If you're getting different contacts on different readings then it will throw off your plot.

Stuff gets,very interesting when you plot one target for the beginning of a three minute timing for course and speed, then ping another target entirely at the end of the three minutes, extend the line to establish the "course," measure the number of hundred yards for the "speed," and surprise! Surprise! They don't go where your plot predicts.
