A lot of my hiking is close to saltwater, plus I like to sail and kayak a bit. I like to pack a handheld (marine) VHF if I'm going to be close enough to water to use it. You need a license, at least in Canada, but it's comforting to have it as a backup. With all the deep and steep coastline here, it's easy to lose cell service even close to town.
I'm not really a fan of FRS radios, but mine are pretty old now though.
