Which item is NOT included in the survival kit of the MPLR and LRU life rafts?

The portable GPS device is not included in the survival kit of the MPLR (Multi-Purpose Life Raft) and LRU (Life Raft, Universal) life rafts. These survival kits are designed for immediate survival needs and prioritize items that are critical for signaling, hydration, and basic survival in emergency situations.

For instance, signaling devices like a strobe light are essential for attracting the attention of rescuers, while a water storage bag is necessary for drinking water and keeping hydrated. A bailing sponge is important for managing water inside the raft, ensuring that it remains buoyant.

While a portable GPS device is a useful tool for navigation and location tracking, it is not typically standard in survival kits because it requires batteries, potential maintenance, and may not be as reliable under emergency conditions when simpler, more essential survival gear is prioritized. The focus of survival kits in life rafts is to provide immediate assistance for survival and escape, rather than navigation technology.
