what area does the sensor on a Hummingbird LCR4000 fish finder cover?

We obtained a used boat with the fishfinder included. It is a Hummingbird LCR4000 and I know nothing about it. My husband wants to know about the sensor. I think he is wanting to know if it senses the front, rear, 360 degrees, or what???? Please help. Thanks, Dawn

  1. Golden Feather Says:

    The area the transducer will cover depends on the cone angle.
    The shallow the water the less coverage, as well the deeper the water the more coverage. Think of the cone as a Pyramid with the point coming out of the transducer.
    Again the area covered will depend on the cone angle.
