In the 777c2 i have manual it says when using the dual beam sonar that bottom coverage is 1 x depth or an area equal to your depth. so while in 20ft of water your bottom coverage is 20ft. Is there a way to know your bottom coverage if you fish using the 200 kHz only?
20* is a trigonometric function which equates to about 1/3 the depth.Quote:

thanks cane pole. I appreciate the info.
