摘要： A location indicating device comprises a container having two partitions therein forming three compartments. Each of the partitions has a hole therethrough. The container is open at one end at a first of the compartments and has a selectively openable cap covering the open end thereof and a hole formed through another end thereof at a second of the compartments. The third compartment is between the first and second compartments. Cord is provided in the second of the compartments extending at one end through the hole in the container. A grappling device is affixed to the end of the cord passing through the hole in the container. A valve is provided in the hole through the partition between the first and third compartments. A collapsed balloon in the first compartment has a neck part connected to the valve. The cord extends through the hole through the partition between the second and third compartments and is affixed to the valve in the third compartment. A valve in the container extends into the third compartment for filling the compartment with buoyant gas for filling the balloon via the valve when the cap of the container is opened.
