An underwater obstacle course kit for use in underwater buoyancy training includes a plurality of identical target sets. Each target set includes a target hoop, a line cord, and a line holder. The target hoop has a sealed interior for excluding water therefrom and for providing a buoyancy to the target hoop such that it is capable of undergoing upward floating movement toward a surface of a body of water. The line cord has one end portion attached to the target hoop and an opposite end portion being attachable to an object on a bottom of the body of water of sufficient weight to resist upward floating movement of the target hoop toward the body of water surface. The line holder is attached to the line cord and has a portion for receiving and storing a selected length of the line cord extending between its opposite end portions to provide the line cord with a desired overall length between the target hoop and the body of water bottom for maintaining the target loop floating at a desired height above the body of water bottom. Different underwater obstacle course layouts can be assembled using a plurality of target sets of the same course kit. They are slalom, escalator and rollercoaster obstacle course layouts.
