A heated hand grip that is adhered onto the grip section of the bow or the handle section of the fishing rod includes a flexible substrate, a malleable heating element, and a power port. The flexible substrate includes a conductive layer and an insulating layer, wherein the conductive layer is superimposed onto the insulating layer. The malleable heating element is integrated in between the conductive layer and the insulating layer. The power port is externally connected onto the flexible substrate as the malleable heating element is electrically connected to the power port. When the malleable heating element is powered through the power port, the malleable heating element is able to provide warmth to the conductive layer which in return warms the exposed hands of the bow hunters and anglers.

Apparatus and methods related to an underbody support for supporting a body of a being, such as during surgery to prevent contact pressure injuries. In certain embodiments, the underbody support may include one or more inflatable chambers enclosing a volume. At least one of the inflatable chambers may include one or more compression sensitive switches for monitoring the volume of the inflatable chamber, and the one or more compression sensitive switches may be located within the inflatable chamber. In some embodiments the one or more compression sensitive switches are sized to close when the said inflatable chamber is deflated to a desired residual volume.
