Hello Stryker19,

Dual Beam -> Allows for higher resolution when sensing in deep water. If you are on the edge of a bank the standard wide angle will most likely show you the shallower depth only. You can switch to the narrow beam to reduce this error because now your are sensing a smaller area. You will be able to see the edge of the bank more accurately.

Dual Freq -> They operate at two frequencies but only one cone width. The better of the two frequencies is 200kHz but the other option is 50kHz. 50kHz can be effected by interference but can sense a deeper depth.

Cheers
Jordan
