I love this trend of PLBs (and gear in general) getting smaller and lighter. With PLBs it means I'll always be able to carry it on my person. With other gear, traveling lighter means less fatigue and, therefore, safer romps through the forest. While I'm not a ultra light hiker/camper, I do realize that and ounce here and an ounce there can really add up.
Ditto, at this rate I'll be carrying one in the next couple years.
Great to see the progress on the PLB front.
