A submersible device for placement in a swimming pool to facilitate the placement of lifeguard stations around the pool. The device includes a base and movable members. The base has a weighted portion with sufficient weight to cause the device to sink to a bottom of the pool. The movable members extend from the base. The movable members have less weight than the base, thereby allowing the movable members to move and sway as the current of water in the pool changes. The device is used to simulate a submerged swimmer/bather in the pool.
