Understanding Livescope Beam Width to Distance
As a new user of Livescope I appreciate the graph which shows both the depth and the distance that my bait is fishing out in front of my transducer, but I was always lost when it comes to where my bait is located from side to side in the beam angle, since bait and fish can look like they are right on top of one another but could actually be quite a ways apart when it comes to the width. In an effort to get a more visible understanding I have listed the width of the beam in relationship to distance starting from the center point of the transducer and going forward. I was very surprised to learn that the width is actually very narrow, especially if you are one pole or spider rigging since you most likely would not be fishing no more than fifteen feet in front of the boat. These calculations are not exact since I have rounded up or down to the next whole number; but they should help to get a better visible understanding on the width that you are actually fishing in.
These calculations are based on a 20 degree beam angle, the first number is feet in front of transducer, the second number is the width of beam.
Distance to Width:
1' ft. - 0.4" inches
2' ft. - 0.8" inches
3' ft. - 1' ft.
4' ft. - 1.5' ft.
6' ft. - 2' ft.
7' ft. - 2.5' ft.
8' ft. - 3' ft.
10' ft. - 3.5' ft.
11' ft. - 4' ft.
12' ft. - 4.5' ft.
14' ft. - 5' ft.
16' ft. - 5.5' ft.
18' ft. - 6.5' ft.
20' ft. - 7' ft.
