WiFi + 3G (the version with a data plan) because it has a true GPS chip vice the AGPS (assisted GPS) in the WiFi only model.

Software- get the Navionics app and you're set.

I agree on the WIFI +3G...and you do not have to purchase a data plan for the GPS chip to function. I have an iPad Air2 with the GPS chip and use iSailor for backup navigation. Its inexpensive, very accurate in my area with regular updates.

I recently added the data plan and now use it as my hot spot when away from WIFI and that has turned out to be a great benefit.

One thing you might consider is getting a nav app that synchronizes with ActiveCaptain. Doing so allows you to create a route in any program that will export in the .gpx format, upload the route to ActiveCaptain and then synchronize the app with ActiveCaptain. Your previously created route will now display in the ipad nav app. MX Mariner for example will do this.

You can always Bluetooth an external antennae device to a regular old non-3G iPad too. The puck stays in place whilst the iPad can move around. This way you can get glonass satellites too.

I have a Garmin Glo. Bad Elf is another highly rated brand.

Appreciate the information. Why would I want a data plan? What size of ram would be recommended? 16, 32, 64 or 128 gb? Thanks again.

Garmin Bluechart works well with the iPad and works with Active Captain.

The data plan let's you have up to date weather reports and weather radar while on the water, Active Captain updates, etc. I wouldn't get one without the 3G.

You don't necessarily need a data plan- but you'll want the iPad that is data plan capable (and the carrier doesn't matter).

Size- it's a computer, so more is better. We have the 64gb iPad, and it serves all our needs.

Learning a lot, now the next question in researching is some advertise that the Ipad is unlocked. What is the unlocked? What is the difference between 3g and 4g? Thanks again

Unlocked/jailbroken means that you have access to the operating system and can install more third party programs and apps. Apple is know for locking their operating system and limiting access to a limited group.

IMO it's not worth the time or effort. Apple works well enough as it is for your intended usage.

Thanks for all your information. I boat is S.E. Alaska where wifi is almost non existent. In your experience would a data plan be worth it? Difference between 3g and 4g?

Speed is the difference. I did mis-speak, as the latest iPads are 4G vice 3G. The data plan is a pay as you go thing, so no contract (as least it is with AT&T).

More importantly, you'll have an iPad with the true GPS chip.

iPad and iSailor with a Dual external GPS ($99.00 Amazon) is what I use. You can import and export all your routes in .gpx format so transferring from say Garmin to iSailor or vice versa is a piece of cake.

Mine is not a wifi version. Wifi is great when you are within range but useless otherwise. Is the added cost worth it? That's for you to decide.

Again. You don't need to buy the iPad with the GPS chip or 3G or 4G wireless. You can Bluetooth an external device to any iPad.

There are advantages and disadvantages.

One advantage is that GLONASS satellites operate at a higher orbit inclination, 64, instead of 55 for GPS. This will give you better coverage at higher latitude.

Another advantage is that it gives you access to twice as many signals, which not only fixes faster, but the antenna is more likely to find a signal when you are in a fjord or behind a mountain.

Things people in the lower 48 don't think about.

Looks like I've narrowed it down to the Ipad 4th generation 4g with Retina Display 64gb wifi + LTE and the software would be Navionics. Now the search begins for the best price. I think I've run out of questions for the moment.
Thanks again for your informative help in helping me understand!

Something to think about! How would that be any different than my standard GPS that is mounted on the boat?

GPS is US, GLONASS is Russian.

Some electronics use both, some just GPS.

It also depends how many signals are used and tracked for a fix.

Actually, it appears that 3rd gen iPads on up (with 3G 4G) also use GLONASS, they just don't advertise it. They use 4 signals for a fix.

Another software to consider is Max Sea. I have it on my Ipad. It seems to work well.

If your cellphone tethers, to form a mobile network with the iPad you can probably try that first. Your phone already has a data plan.

The 3G versions do have GPS, a must-have and many carriers allow a modest add-on to your existing account for a tablet. And the Russian version GLONASS as mentioned. So you get two legs on pinochle.

There's a chart of the iPad specs at https://en.wikipedia.org/wiki/IPad

I'm using a Ipad 4th generation 4g with Retina Display 64gb wifi with Navionics. Battery life isn't that good so I'm looking at the possibility of using my 15"Macbook Pro Retina that has fantastic battery life and my poor old eyes don't need to strain so much.
