Its actually because the fish's blatter reflects the transducer signal the best while the rest of the body reflects less as the signal passes over and below the fish thus making an arched signal. Mty

I was told by the lorance reps that it is because as the fish moves across your cone it you get less bounce-backs on the edges of your cone and it is farther away from your transducer when it is in the center of the cone you get the best bounce-back and it is closest to your transducer. Also if a fish stays in the same place in relation to your transducer it would show up ad a solid line.

I agree with that statement, it makes sense if you think about it the signal refraction from the signal to the depth of the fish/air blatter. Marty
