Abstract: The device of this invention is for use in marking, locating and retrieving an object with respect to the user, and has particular usefulness for hunters and the like to assist in locating a hunted game that has fallen some distance from the hunter. The device is an object that can be fastened to or hung from a user, can be easily removed from its attachment, is hand-holdable in size, and light weight for being launched or thrown toward the location to be marked. Once places and after a reasonable time delay, the device can emit sound, light or electronic signals that can assist the user in finding the marked location. The device can be have other uses as an assist in returning to a located place after the device has been launched or placed.

Abstract: According to one embodiment, an apparatus for reading a temperature of a material includes a thermistor that is communicable in temperature sensing communication with the material. The apparatus also includes a first resistor that has a first resistance and a second resistor that has a second resistance that is lower than the first resistance. Additionally, the apparatus includes a switch that is selectively controllable to electrically couple the first resistor and second resistor to the thermistor in a low temperature mode. The switch also is selectively controllable to electrically couple the second resistor to the thermistor and electrically decouple the first resistor from the thermistor in a high temperature mode.
