Index of Subjects Cost is the likely "excuse". Even if it is now a weak justification if it ever was one. Most "cheap" and "small" beacons use GPS to determine their position but rely on cell phone networks to broadcast this information. They cost a few 100s (i.e. MEC carries one for $300 for backcountry activities), may require a subscription with a service provider, and use is therefore limited to "civilized" environments that provide required infrastructure. Some of the small GPS trackers used in wildlife studies need to be recovered to read out the data stored during use, or the researches have to get close to pick up the transmitted signal with radio receivers or via cell phone networks. Independend from local infrastructure, and therefore useful in the middle of nowhere- are beacons that transmit upon activation a radio signal -with or without location information, depends on the model- that can be used to triangulate position by search teams or is powerful enough to be picked up and relayed by satelites. This technology was used in liferafts and airplanes for decades and is now a only a bit more expensive ($500-$1000) and only la ittle bit bulkier (like a VHF handheld marine radio) than the GPS beacons mentioned above. Such EPIRBs (emergency position indicator radio beacon) have to be registered with authorities and need replacement every few years. I have to agree with you and wonder for some time why such widely and cheaply available personal safety equipment is not carried by folks that face the risk of getting into serious trouble, and think it should be even made mandatory for commercial operators. Better chances for the folks that get into trouble and better for S&R crews that can limit their own exposure to risky conditions.
