I love mine, I have had both the 530hxc and the 655t. They are a great tool but the features won't be fully utilized unless others in your party has one. My buddy and son and law has one, and we are able to keep track where each other are during the day, ect... The weather radio is nice too. They will communicate with other handheld radios if you want to use it that way, but tracking your partners or sending them waypoints won't work.
