Our SonTek M9 River Surveyor has so far been deployed using a laptop computer. Although our Toshiba Toughbooks are pretty field-ready, this is still a slightly awkward way to deploy this system. I’ve been playing around with a WinBook TW700; these cheap little tablets are running Windows 10 and available for under £70 all in. I installed RiverSurveyor Live (Tablet) on it, and the on-board Bluetooth works fine with the M9. The removable microSD is perfect for data storage and transfer. I bought a cheap 7″ touch-screen compatible case for it. It’s perfect for use on small inflatable boats and for bank-side use.
