If your boat's meter reading is above the currents listed and you don't have down riggers with PIC built in, you can purchase a black box. ProTroll, Cabelas and a few other places sell them. They generally run around $100.00 and are easy to install.
Note: If your boat is aluminum and reads couple tenths above the voltage listed you want to start looking for a bad ground or wiring that is bare and coming in contact with the hull of your boat. Galvanic Corrosion is a serious issue on aluminum boats and these stray currents going into the hull of your boat can leave huge pits and corrosion that will eat through the hull of your boat over time. While this pitting will generally occur inside the hull below the water line, on some boats you will see small pitting on the outside as well. Sacrificial zinc anodes on your hull and motor are something that should be inspected and cleaned or replaced regularly on all aluminum boats as well if your boat is reading hot. A very hot boat can be symptomatic of big problems.
