Size of fish hole affects flasher inteference?

[fisherman-andy]

Since my ice auger only drills 8inch holes last ice season fishing along my buddy we used his new 10inch auger.

Maybe it's just me but when I drop my Marcum's be it the VX1 or LX3tc into my 8inch hole versus the 10inch hole I tend to notice more interference on screen. Even if I adjust it.

So it seems that the larger 10inch holes cut allowed the Marcums to have less interference or almost none. At first I thought maybe it was just a coincidence but I cut a few holes side by side and sure enough the smaller holes had more interference showing up on my screen. Either that of I am just very confused.

theoretically, you should have the transducer sitting just below the ice level, so anything in the hole shouldnt have any effect on the screen...shouldnt it?

I have always noticed some interference with the ice if your not below the ice. It only shows up on the top one foot or so of your read out. I have always been able to deal with it. It seems like new ice is less likely to affect it then late season thick old ice.

Good Luck fishing
