navionics app

[NormanB]

I use the vanilla standard Navionics on both my iPhone and iPad and cannot detect any difference in resolution between the two devices. BY that I mean, if I zoom right in I seem to get the same degree of navigational data and information. I use the iPad for route planning, surveying the planned route for hazards by zooming in to the nth detail and have never had an issue, it all compares most favourably with the printed charts. The planned route is synced with the iPhone so I have two devices loaded with the days route. The iPad sits on the chart table at sea, plugged in and I keep the iPhone in the cockpit table, the iPhone is in a Lifeproof nuud waterproof case. I have a portable battery (capacity to charge phone 8 times) plugged in to the iPhone once underway and on passage). For areas of more detailed navigation and pilotage I keep the iPhone in my pocket ready to hand. I also use a Bad Elf GPS dongle for the IPad (because I purchased the wifi version of the IPad without realising the lack of true GPS capability).

When I was out in the Ionian early this year I reported the removal of the sand spit at the North of the Lefkas canal and the massive amount of dredging that had occurred in the canal since last year to Navionics, they issued that chart amendment mid August - pretty impressive correction time. To top it off they extended my subscription for free as a thank you.

All in all I like Navionics, its deployment to hand held electronic devices is a useful development and a great aid as long as you recognise the inherent issue of knowing exactly where you are on a 200 year old chart. I always - always use a paper chart and plot hourly fixes when and where I can (I cannot use a sextant - but it is on my to do list).

I would be much less comfortable to sail without the system I have described above.

Agree about screen size. It's OK on my Nexus 7 but I would not want to be any smaller

I have it on a 10" tablet, but actually find myself using the iPhone on passage. The tablet is good for planning, but the reality is the small screen size of a phone is still perfectly adequate for threading your way into anchorages etc,
Your not glued to the screen, it's just a glance now and again to confirm where you are in relation to landmarks and rocks etc and the course to be steering. Most of the time is spent looking ahead or around.

Comparing the same App on different devices will always show the same detail. The OP was asking about the difference between two different Apps.

I would like to know the difference too. If you take an example, the island of Broken in Sweden. If you look at position 58 42.755N, 17 14.383E via the online Navionics WebApp (https://webapp.navionics.com/) you can clearly see two pairs of red/green buoys which have been there for some years. These buoys are missing on my iPhone version of the Navionics App (Marine Europe), despite the charts being up to date, so there are clearly differences between the cartography. Can anyone with the HD version of the App tell me if these buoys are shown?

If you want to know the difference read post #9. Both screenshots are from apps with charts updated that day and displayed on the same device.

Edit: the difference in depth colouration in the pics in post 9 is due to to different "safe depth" settings on the two apps, which can be changed to give identical colours.

My post was attempting to pick up on the sense conveyed in post#3. I stand by what I say.
