It seems there is no "cheap" way to get the latest UK charts with relief shading for use on chart plotters not supplied with it. SD Cards with the latest charts are expensive add ons & new plotters bundled with the latest charts reflect the price too.
You can get a free 2 week trial of the Boating marine & lakes app for your phone/tablet to take a look at what your missing. I did this and found it quite an eye opener for local fishing marks and was able to pinpoint some marks which I transferred to my Garmin DV45 for use later.
I also took screen shots to refer to once my free trial ran out.
I really wanted to see more at any one time than my phone could show and tried casting to my 50 inch TV, that worked but was a little clunky, size was the same format as on the phone, no full screen & only possible when the family didnt need the tv.
I dont own a tablet, that would have been ideal but it needs to be Android 6 or later with Glonass GPS I believe to get the most from it and thats getting costly again.
I really wanted to be able to use the app on my 24 inch PC monitor but that didnt seem possible, then I stumbled across an app while trying to link my Samsung S9 phone to the pc by usb lead.
Samsung DeX app allows Samsung S8 onwards phones to connect to use the screen of your PC. DeX for PC app available from www.samsungdex.com
I think its also possible to port to your hdmi TV with the right lead.
Other apps like flightradar & VesselFinder also benifit from being full screen
So I can now browse on a large screen any area around the UK, Kent is my main interest, in fact the charts are so full of information that over the winter it will be like browsing a good book. I was so impressed I spent £35 on a years subscription to the Boating app as a little xmas pressy to me.
