I just got a Dragonfly and used it only two times so far but it's pretty sweet. It seemed easier to use with a cleaner interface and less buttons and options to dig through, and the imaging is awesome. The HDS seemed to have way too many options (engine, Sirius, networking, etc..) that I didn't need for a kayak, but it has some great abilities. So far I'm happy with my purchase. Go to WM and try them out side-by-side before you decide. Either will do a proper job.
