A hydrophone assembly for deployment on the bottom of a body of water is vided wherein a plurality of hydrophones are mounted in a spaced apart relationship about the circumference of a housing which is designed to hold signal processing electronics. Each hydrophone is constructed to detect a range of frequencies within a defined receive angle that extends outward from the circumference of the housing. A resonance absorbing material is interposed between the housing and the hydrophones to isolate each hydrophone from mechanical resonance. Tilt switches are connected to each hydrophone for automatically and independently selecting hydrophones to participate in the output of the hydrophone assembly based on the orientation of the hydrophones. Selected adjacent hydrophones define a continuous receive angle formed by combining the receive angle associated with each adjacent hydrophone. The continuous receive angle faces upward from the bottom of the water to include an angular portion of the surface.

A swim fin having open instep and heel portions. The swimmer's foot is retained in the fin by means of an instep strap configured to pass over the instep of the foot and a heel strap that surrounds the heel of the foot. The instep strap passes through a pair of longitudinal slots in the planar foot portion of the fin and up and over the foot such that the ends of the instep strap are secured at the instep. Preferably, to facilitate adjustments, the ends of the instep strap overlap one another and are secured with hook and loop fasteners. A locking strap overlays the instep strap at the instep of the foot and further secures the fin to the foot. The instep strap conforms to the instep of the foot and lends itself to enclasping the arch of the swimmer's foot. Preferably, the heel strap is integrally formed from the instep strap and the ends of which overlap one another are secured with hook and loop fasteners. A heel locking strap overlays the heel strap at the ankle and further secures the fin to the foot.
