Having a chart plotter, fish finder and radar on your iPad is possible, but who wants to hold a mobile device while running a boat, especially with the possibility of it falling on the deck or getting drenched with spray. Enter the Snow Lizard SLXtreme Navigation Series waterproof, shock-resistant cases. Designed for iPads, the cases fasten to a standard VESA (Video Electronics Standards Association) mount (sold separately) for installation. Now your hands are free to drive.
These cases also embed a Bad Elf 66-channel WAAS-enabled GPS. With a Wi-Fi-only iPad (Gen 4), you can access latitude/longitude, speed and GPS tracking through a number of navigation apps. A battery booster doubles the battery life. $349.99; snowlizardproducts.com
