OK, i've been waiting to buy a galaxy tab a9+ (11 inch) for a while now - I want Navionics AND OpenCPN and the ability to hack up my own apps.
Catch of the day just announced they were closing down so I went there and look what I saw:
www.catch.com.au/product/samsung-11-galaxy-tab-a9-wi-fi-64gb-graphite-27493720?st=135
Great - but I'm impatient so I logged in, went to the cart, added the FURTHER10 coupon code then took a screenshot and went down to JB Hifi.JB sold it to me for 218 bucks! So for 218 bucks plus the cost of Navionics you have a GPS enabled 11 inch chart plotter that you can connect to the internet via your phone and charge if from a USB battery pack.
Boom!
I've done the same thing but with an iPad this year. Tossing up between Navionics and Lowrance C-map premium. Can't make a choice yet as it's our off season during the wet season.
