Human: I'm looking for a good, cheap, portable GPS system to use while hiking. Any suggestions? Assistant: 
A good, cheap and portable GPS system you can use while hiking is the Garmin eTrex 30x. It has a bright display, an altimeter, barometric pressure sensor, compass, and preloaded topo maps of the area you're in. It's also waterproof, so it can handle being submerged in up to two meters of water for up to 30 minutes.
