A trigger system for use with a downhole tool. The trigger system may include a first housing forming a first pressure chamber at a first pressure and including a membrane positioned in a wall of the first housing, a piston disposed at least partially within the first housing and shiftable from an initial position to an actuated position to actuate the downhole tool, and a trigger. The trigger may include a second housing sealed against the first housing proximate the membrane to form a second pressure chamber at a second pressure and a rupturing member positioned within the second housing and operable to pierce the membrane to balance the pressures within the first housing and the second housing and shift the piston from the initial position to the actuated position.
