Our depth measurements are derived from our own Pro Staff field testing under specific conditions. Those conditions may not be similar to those of which you may find yourself fishing in. Speed over ground, underwater current speed (and direction), type of lure or flasher, diving plugs, heavy vs light spoons, fluorocarbon vs mono leaders all play a significant role in where copper fishes in the water column.

These sink rates are estimates and should be used as a reference only.   Conditions of measurement were fishing directly into a current, 2.7 gps speed, fluorocarbon leader with magnum spoons.
