I don't have a plotter display at the helm
. So I use my Navionics app on tablet somewhat like a GPS
navigator in a car in browse mode ..... just to keep track of where I am and show my position relative to the various markers. It's great when in a narrow channel with various inlets and confusing markers (sometimes hard to work out which is upstream/downstream), and I have found the accuracy spot on (Brisbane to Sydney
Being updateable on demand it should be more accurate than my 6-7 year old charts
in the plotter. The plotter is older technology so I will not be doing any updates to the charts.
The tablet is also great to take to the saloon
table and discuss options for a trip. But I would not try to use it for proper route
planning or waypoints. For that I use a paper chart, and also mark my track on it periodically. The boat's GPS plotter gets used less often.
My PC will have a bigger role in my next trip, but that is getting a bit off topic. For the Navionics app, although the price
has gone up, I would recommend it to anyone with a compatible tablet, but not to buy a tablet for the purpose.
