2101436 9213606 PCTABS00014 An underwater obstacle course target hoop (40, 54) for use in underwater buoyancy training includes a plurality of hollow tubular members (42, 56), a plurality of connector members (44, 58) interfitted with all but two adjacent opposite ends of the tubular members (42, 56), and a pair of separate end caps (46, 60) respectively attached to the two adjacent ends of the adjacent pair of the tubular members (42, 56) so as to define an escape gap (50) between the two adjacent ends of the tubular members (42) for preventing entanglement of a diver with the hoop. The tubular members (42) and connector members (44) define upper and lower portions (40A, 40B) of the target hoop (40). The tubular members (42) of the lower portion (40B) of the hoop (40) contain a plurality of apertures (48) for permitting entry of water. An elastic cord (62) can be employed within the interfitted tubular and connector members (56, 58) which retains the members in interfitted relation but permits the members to be pulled apart and the hoop (54) collapsed.
