I actually have a GPS unit that has a barometric pressure sensor and a pressure plotting utility on it. I have only had it since September, but I have noticed that the fish seem to begin biting when the pressure starts dropping and stop when the pressure bottoms out. Thus, It may be more of a function of the change in pressure than the actual pressure, but either way, I believe that things are definitely effected by pressure.
