Clunky Nav Tool Rugged Enough, but Obtuse Maps Don'...


Our reaction on opening the box: Ew! But like a pug, the iFinder is so ugly, it's almost cute. Unfortunately, the performance is less lovable. Proprietary

High-contrast, multi-colored screen. Survived 5- and 10-foot drops, and even repeated dunkings

FreedomMaps deny you the freedom of detail; we have never seen a more half-baked topo maps. Bulky and inconvenient to carry. Device alerts you to marked waypoints with shrill, panic-inducing alarms
