gain this has probably been asked and answered a hundred times...my old eyesight aint what it used to be and i defo need a bigger screen just wondering best budget tablet to buy and if its bigger will it fit or need an extra mount i see loads on amazon. any help appreciated.

I think they should suggest you not the cheapest, not the most renowned, but the brightest, the one that has the screen producing the most nits (cd/m2), that's what you need most of all, especially nearing the day of solstice.

I use an iPad mini 5 but hear that the 4 works as well.

You can get good used I pad on eBay but you have to fly in WiFi area if you don’t connect it with your provider

I see loads of folk using amazon fire? no gps but I suppose you could tether it to your phone on a hotspot?
