Is a tablet computer a good tool to use for marine navigation? (A question related to the accuracy of a tablet computer GPS sensor when there is no WiFi or carrier based signal available)
Background: I have 2 personal watercraft (a Waverunner and a Seadoo RXT). My wife just gave me the greenlight to buy a GPS to navigate on the water. I also want to get a tablet computer, so I'm trying to sneak in that purchase by using the tablet as a GPS device.
I'm having a hard time nailing down definitive answers regarding using a tablet in place of a traditional GPS or chartplotter for navigating on a boat. I know that some tablets have integrated GPS sensors however I've been told by multiple sales people that those sensors are ineffective without a WIFI or carrier based signal. Because of that, they say that a tablet is not a good solution.
In conflict with those statements is that I've seen a number of mentions on the internet indicating that a tablet works very well. In fact, there are a number of apps sold that are specifically designed to do this including Navionics and EarthNC.
Setting aside the obvious issue of waterproofing, is a tablet computer a good tool to use for marine navigation?
