Claim 14:
15. A method of making an automated inflation device comprising
a) making a housing with a cover, wherein the housing and cover are joined to each other with a watertight seal, and the housing has a first opening able to attach to a gas cylinder and second opening able to attach to a valve of a flotation apparatus;
b) attaching a manual release having a handle and a pull cord, wherein the manual release is connected to a manual release cam inside the housing;
c) installing a trigger mechanism having a circuit board that is connected to a battery and at least one sensor, wherein the circuit board and the battery are enclosed within the housing, and the at least one sensor is capable of detecting a presence of an aqueous medium outside of the housing;
d) installing an automatic release mechanism having
i) a plunger arm that has a near end mounted on a first pivot pin and is constrained axially by the housing and cover,
ii) a plunger arm stop that has a near end mounted on a second pivot pin and is constrained axially by the housing and cover, and
iii) a plunger arm spring that has a first end engaged with a far end of the plunger arm and tension is applied to the plunger arm,
wherein the plunger arm stop is engaged with the far end of the plunger arm and prevents an inactive plunger arm from rotating about the first pivot pin; and

e) attaching a bore having at least one O-ring and a piercing pin capable of penetrating an aperture of the gas cylinder.
