Abstract: An underwater retrieval game system employs a submersible target having a combination of features that make it difficult to locate underwater. The body portion of the submersible target is translucent and has a density greater than water. The target may be tossed in a swimming pool and sink to the bottom. A game player may jump into the water and try to locate the target. A combination of additional features such as size, shape, and surface texture may make it more difficult to spot the target underwater. A submersible target may comprise a detection device, such as a small light, that is activated after a certain period of time or is activated remotely by a wireless signal. A game player may be challenged to find the targets before the detection device is activated, for example.
