No, it's closer to 8'. When I swap the MFD's from the console to the bow, the depth is off. I've thought about looking in the instructions, to see where the depth offset is. Or just make a mental note of it.
Otherwise I'd be changing it Everytime I swap them.
I put them where no one should be running more than idle speed. If I remember correctly, the barrels measure 33" tall. The lowest I've seen the lake is 2.5' below pool.
