COMP Cams Magnetic Deck Checker Volt Meter The 8 Hole Top AirTo calculate true compression ratio it's necessary to measure the distance between the deck surface of the block and the piston deck. Our machine aluminum deck checker incorporates magnets to hold itself firmly to the block for simple and accurate measurements.
