The RAILBLAZA ScreenGrabba is a simple, cost effective and flexible way to "grab your screen".
Many iPad holders are just that, an iPad holder, the RAILBLAZA ScreenGrabba will hold an iPad, and many other tablets.
Many outdoor situations will require your iPad to be in a waterproof case - this is no problem for the ScreenGrabba, simply place the iPad in it's bag, put it in the ScreenGrabba, and clamp it in, easy as that.
Once your tablet is in the ScreenGrabba you can easily move it from StarPort to RIBPort to RailMount with the flick of a locking slide - it really doesn't get any simpler.
Once you have decided to buy a ScreenGrabba you simply need to decide how to mount it, do you need it on your rail, inflatable tube, in the cockpit or on the flybridge? Your choice.
