Sand Shark/Beach Question

[bucketheadben]

I just got my Sand Shark this week and I'm not sure if this is typical behavior. When I'm in the surf, right before a wave hits me, the threshold will get higher and then drop as the wave passes. Is this normal? I'm I doing something wrong? It just seems odd to me.

Is the machine completely underwater when this happens?

It doesn't seem to matter if it's underwater or not. It seems to "sense" waves if I'm in knee-high water or up to my chest.

Maybe you're inadvertently lifting the coil off the bottom in anticipation of the waves.
Or the waves are lifting it off the bottom causing the fluctuation.
I hunt almost in silent mode and when I lift the coil off the bottom, even slightly I get
a false signal which varies depending on the contour of the bottom.
