My Aldi tablet gave up the ghost so I bought a Lenovo A8-50 tablet which has a GPS chip for $234 including 3 year extended warranty from JB Hi Fi. Seems to be a good unit.
First thing to put on it of course was Navionics. I had a good look in Google Play store at other Apps marine related.
Can anybody recommend any other marine type apps?? Is there one that will give me a lat/long read out??? Navionics does not do this.
I like "PocketGrib".
You can download a map for any area then have data for wind speed and direction, atmos. pressure, rain, air temp (which I turn off) with five day forecasts.
I have the same question for iPad......
preferable off line
I use nice GPS readings from ....Where am I....app.
iSailor for iOS will give lat long as will native compass app. Are you sure navionics doesn't - it's using the info constantly so surely it can display It?
My Aldi Tablet also gave up after a year. Will check out the Lenova. A good app I use is GPS Test. It will give you Lat Long as well as similar stuff to a simple hand held GPS. it also shows which satellites are in view and use. App is free.
Thought it was too good to be true! Googled your model and it says that it has a Google based A-GPS which is not a true satellite based GPS (as far as i know). I have been looking for a replacement tablet for my Aldi, with true GPS and SIM card, and so far cannot find anything on the market.
I was about to mention the A-GPS vs GPS thing as well.
Assisted GPS uses telco towers and wi-fi identifiers to better triangulate your position, hence is not very accurate at sea where either or neither will be present.
A dedicated SIRF 3 GPS chipset is required if you are going to use any software with a degree of accuracy.
the iPad is A-GPS. OK for inland waters and very close to shore (in built up areas with phone reception).
Maybe try Androzic, it's an Oze Explorer clone for android although I believe Des has released a beta of Oze Explorer for Android as well.

If you tap the screen on Navonics it will give you the lat. long for that point/position, but no it doesn't give a lat./long. grid.

The link above no longer seems available, so I don't know what Nav application they were using. But the comment about heading doesn't seem right to me. With Navionics (and another app I use, Jeppview), I have noticed that initially, the position inicator (a triangle in both cases), does seem to wonder a bit until a positive track has been determined. At that point, the triangle normally stays steady showing the 'track' and not the 'heading'..

1/1000 of a minute is a couple of metres, isn't it? That's pretty tight.
DrRog, the Jeppview app I mentioned above is accurate to within 2 metres. I don't know the accuracy of Naviaonics or other nav apps.

It's not the accuracy of the app that you should be concerned about, but rather the accuracy of the charts in the app, the GPS will always tell the truth but the map may not.
Navigon was already on my Samsung. If you select "co-ordinates" from the opening page it displays your current GPS position in either degrees minutes and seconds (which is what I use) or decimal degrees.

The Lenovo A8-50 has a GPS chip and is not A-GPS. Have a look at the display demo unit they have in the JB Hi Fi store and have a play with it. Go into settings/location access. It has GPS and network/WiFi positioning.
There are three versions of this tablet.
1. Plain Jane no micro SD or SIM slot.
2. Better Boy with micro SD slot but no SIM slot. (The one I have.)
3. U-Beaut with micro SD and SIM slot (data only, no phone app) which is apparently not available in Aus.

Is there one that will give me a lat/long read out??? Navionics does not do this.
Navionics will give you a lat/long read out, just not a continuous readout as you travel.
If you want a lat/long reading at, for instance where your boat icon is currently, all you need do is just quickly tap on the screen at that location and a little call out pops up on the screen which has "More Info" on it which you access by tapping the call out.
You can also tap anywhere else on the screen and the same call out pops up with the same deal as before.
In order to tap accurately I recommend you use a stylus rather than a fat finger.

Some good, some not so good but most are free.
I downloaded the Navionics AusNZ HD version for $60 odd which is supposed to be optimized for tablets. I did not think the resolution was that good at all so then I downloaded the $16 odd version which was just as good as the other.
I then went back into Google store and clicked "refund" on the $60 version and that has happened.
I was unable to retrieve the Navionics program that I installed on my Aldi tablet over a year ago because it was "over a year ago". It seems if you have it on your device you will get free updates for a year and after that if your device keeps chugging, so will the App but without any further updates.
If you have Navionics on an iPad, you can turn it into a sounder as well by buying a particular transducer that will communicate by WiFi with the iPad. Pretty amazing stuff.

Wasn't aware of that. So if I tap on the red arrow (my current position) a lat /long will be displayed. Is that correct???

With the one you have Cisco you will always be reliant for a Wi-Fi signal, which is not always easy or reliable to get.
Option 3. the U-Beaut one then makes it the same as an iPad in that no iPad has phone function either. Hence the reason I love my 10.1" Samsung Galaxy Note.

Yes, that should be correct, that's what it does on mine

Yes, that is exactly my concern. I want a lat/long readout that I can plot on the paper chart so as to compare with the app map, also to have a record on paper.
sound good unit, next step is download app offline map
and test GPS.
should be as good as any other Nav. device.
not sure how friendly is an accesses to ext. micro sim, but
but we found on latest Samsung 10.1 system blocks to use it
unless you "rooted" that looses a warranty and open unit to virusis.

Definitely not. It does have a GPS chip and gives me position without WiFI.
What it also has is GPS EPO assistance (Extended Prediction Orbit) which is "one of MediaTek's innovative proprietary off-line server based A-GPS technology. It supports up to 30 days satellite orbit prediction, which can be used to greatly enhance user experience by improving GPS Time To First Fix (TTFF)."
I did my research before buying and you should know by now that I am a lousy bustard and you need a crow bar to get $234 out of my pocket.

Sorry, you misunderstoof, I didn't mean that it needs the WiFi for GPS but rather it needs it for data transfer.

Yes I have got you now but the Navionics maps exist on the device and therefore the unit does not need data transfer except if you want to look at the photos where the camera icons are on the maps.
That is the beauty of Navionics. It is stand alone without network of any kind as long as the device it is on has a built in GPS chip. It will not work for navigation on say a lap top with a USB plug in GPS puck.
For real time navigation, the device it is on MUST have a built in GPS chip for it to work outside of network range.

I just finished a RYA theory course and was amazed to learn that some soundings were made over 100 years ago using lead lines... Paper charts it seems, can be rather inaccurate as well. That being said, the link above talks about digital nav as PRIMARY means, and I don't believe in that either.
The Jeppview chart I was referring to above, is used in a professional capacity. The charts are verified and it cost my company $600,000 something per YEAR, for all us employees to have this 'app' on our iPads. When the iPad believes it does not have the information requied to give an accuracy of 2mt, an alert is given and we are not allowed to use it...... Even with this accuracy, it is still NOT our primary means of navigation......
