Oh you have a K2 you bought for $500 and want to easily send and track things with smartphones that have been around for a decade? Too bad, pay another $500 for all new hardware and one slightly improved codebase of software, so now you’re $1000 out of pocket equal to or more expensive than a smartphone itself, for software features that could be a patch. Mind you one major draw of the Hammerhead is that it’s basically a smartphone with robust software capabilities.
