Fishfinders scroll from right to left. What you see on the very right is what is under the boat/kayak right now, what's to the left of that, is what was. Like greg said what your metering may or may not be directly under your kayak but just in the sonar cone, the object/s could be off to the left or right, forward or back. 200khz is narrow beam and 50khz is a wide beam, 200 is generally used for shallow water and 50 is used for deeper water.
Confused yet?
