Just stayed at Cwmdu campsite with my caravan and did bits & pieces of the Beacons Way. Campsite mainly seasonal caravans but lots od space for tents. Toilets & Showers etc. Had reasonable meals at nearby Farmers Arms & Mynydd Ddu Tea Rooms.
I'm not sold on stand-alone GPS units and favour either a Smartphone or 7" tablet which provide more uses. The latter has a bigger battery than my Smartphone and lasts all day. If you still have access to your Anquet maps through their "cloud" services then I would suggest you look at this used in conjunction with a 7" tablet.
I run Anquet mapping on my Samsung Note phone and a Samsung Tab2 7.0 tablet and have been highly satisfied with the GPS accuracy of both devices. The tablet recently started to give problems (freezing) and nothing to do with the GPS - I think?
I bought a new Samsung Tab4 7.0 tablet and have been checking the GPS accuracy against that of my phone. At times the new tablet gives the same readings and provides the same tracklog but at times it jumps about a bit and can be as much as 100m off.
Can anyone explain why this might happen and what I can do to fix it?
