Anyone using Inavx and Navionics on Ipad?

[PCUK]

As title. InavX seems to be a proper chart plotter for Ipad at $49.99 and the Navionics UK chart 28x is only $39.99. A fraction of the usual price for the comparable plotter card.
I'm wondering what the catch is!

Lots of previous threads I have used navionics it does what it says but the overall opinion is it's not a total replacement for a plotter but getting there

Usual provisions water proof shield from sun use paper etc

I agree with Scottie. I have messed around with the Navionics plotter on my iPhone 4 and found it very good most of the time. It's very accurate. The only issue I have is that for some reason the gps signal and chart loading is patchy in terms of signal, hence speed. Even when I have good 3G coverage and my "proper" plotters are working perfectly, the iPhone seems to struggle sometimes. For that reason I would not use it. I know you are talking about an iPad but they are obviously very similar so I mention my experience FWIW.

Having said all that the idea of an iPad (or similar) on board is a very interesting proposition with many benefits. Logically, it's got to be the way to go in the not too distant future.

asteven, I agree. I have a wi-fi only Ipad but have just bought a Bad Elf external GPS receiver that can be used with an extension lead so it can be fixed inside the windscreen which should solve reception problems.

I used the ipad as the sole plotter last year to sail from ostende to london, it worked like a charm. inavx and navionics charts, with a silicone skin, kept in a ziplock bag. The only minor drawback was readability in bright sunlight.
