Android chartplotters

I have read a lot of discussion about ipads and phones as plotters, but not seen a whole lot of detailed discussion and even less on android, so wanted to open up a thread vs listing a mod. Below is what is working for me and I am hoping others will be able to share what is working for them. Many mac owners are “frugal” (my goal was $150-200) so for that reason I hope it won’t turn into an apple vs android debate.

Also I was only interested in something that would operate 100% offline with no subscriptions or fees.

I already have a handheld garmin gps and 10” MSI wind with seaclear, so wanted something to bridge the gap at 5-7”. 10” tablets felt too big to practically mount in a car and at the helm of the boat. The netbook with seaclear connected to a gps worked for planning while on the boat, but was not really what I wanted on the water and the screen was no good in the sun.


I did quite a bit of research on tablets with built in gps and in August bought a dropad A8X. The primary selling point was that it uses a Samsung SPC110 1ghz processor which is 5V and said to use about 1/3 the power of comparable processors. In GPS navigation mode I have ran it for 6 hours straight without recharging and had battery left.

It has 2 usb ports and charges and transfers files through a standard usb port. For the boat/car I picked up a 12v cigarette lighter to usb adapter and suction mount when I ordered it. It fits perfect in a quart freezed bag while in the mount and I have used it in the rain a couple times.

Charging it runs on a 500ma/5v (2.5w) adapter so the draw on the boat is minimal unlike a laptop. Standard it comes with an 8gb micro sd for a hard drive and 512 of ram. If the 8gb fills you can always just plug in a cheap flash drive if you want to take some extra movies or files with you. It also has some other cool features like a metal case instead of plastic, 1020p playback and HDMI out port for playing on a monitor.

For navigation I installed a couple programs. Some are free, some have a price, all can be easily downloaded for free depending without any special steps. I also downloaded several 100% offline GPS car nav apps if anyone is interested in the pros/cons of them.

If you are familiar with seaclear this looks almost identical. To use offline you have to preselect the area you want by drawing a box around it and download the maps. You can download about a 10milex10mile area at a time with the full version. You can save as much as you want. You can also set it to download/run topo maps, relief maps or street maps. It is fairly easy to drop pins and setup routes and it allows 2 finger pinch zooming. There is a high contrast mode which is good for direct sunlight. I find the tablet is fine in all but sunlight directly on it with the bimini down. I like this one for planning the best.

All the screenshots are of the same inlet so you can get a comparison idea.

Navionics

Navionics http://www.navionics.com/MobileMarineFe ... pe=Android

Probably the most userfriendly. The whole East Coast downloads at once. It seemed cartoony to me at first after using seaclear, but is probably the easiest to visually follow and use. Planning a route is just tap tap tap each waypoint. It leaves a track if you want and a nice feature is it beams out a straight line in the direction you are heading so you can easily see your heading. (great for the lady) Same as flytomap but unlike earth nc you can set a min depth to change the color on the map. In the pictures white is over 6’ and blue is shallower. This is very nice for following new channels. There are also many other features form when you are online such as winds and tides and you can program fuel consumption. It is only portrait mode and you have to press the zoom buttons vs pinching. When you update it contains both the official updates as well as all the info private boaters upload to the maps.

FlyToMap Chesapeake

http://www.flytomap.com/ftm/ViewMaps.as ... =Watermaps

I searched Chesapeake bay in the market and found this one by accident when I first got the tablet. It was $2.99, so I figured why not. Now it is the only paid app I have. Overall this one is a bit disappointing. It works but is not as nice as Navionics. I can not figure out the menu to plan routes. It tries to cram too many depth readings onto the screen. Either I just don’t know how to use it or it is still under development. It does orient both portrait and landscape and have pinch to zoom.

I just put this up for the picture. But it is a basic suction mount and holds fine on the side or top of the helm. Next to it is a 3.5” gps for reference.

If interested I bought everything from pandawill.

http://www.pandawill.com/dropad-a8x-7-i ... 47544.html

Shipping is free and took about 2 weeks. The costs were dropad $195, mount$5, 12v adapter $1, Hard zipper case $3, and spent $3 on flytomap. If you look online you can get 20% off pandawill discount codes, so everything together is still under $200.

So that’s my writeup on a budget plotter. I know a lot of others are doing the same and others are considering it. Feel free to ask any questions and add in your 2cents to help anyone who has one or is considering buying one.

Very interesting post. I appreciate the info.

I'm happy with our present setup with the SeaClear on the computer in the cabin and I can position the screen near the companionway where I can see it, but it would be even better to have a daylight screen at the helm. I just can't find a daylight monitor that doesn't cost an arm and a leg.

We bought a 16 inch 10 watt LCD screen to use now with the computer below on the Endeavour and I also bought a VGA splitter so I can now run 2 monitor off of the computer. In addition to the monitor in the cabin I'm going to experiment with running the 9 inch monitor at the helm under the Bimini and see if I can figure a way that it is visible, but I'm not to optimistic about it happening.

It sounds like what you have is more visible in an outdoor environment than our monitor. Is there anyway with the USB ports to have it act as a display for another computer?

At present we do have a handheld Garmin 76 at the helm that is connected to the computer/chartplotter below and receives waypoints from the SeaClear on it before the day's journey or on the fly if we change it at any point during the day. I really would not like to give all of that up at this time. We don't have detailed maps on the handheld, but are able to go from waypoint to waypoint very easily even in narrow channels.

Thanks again for all of that info,

What you need is a tablet, laptop or monitor with one of these sunlight readable displays: http://www.pixelqi.com/products

The 10" version is already available for a reasonable price and can be fitted into select laptops. They are supposedly developing a 7" version. They talk about tablets being developed with the screens built-in but I haven't seen any for sale.

Thanks for doing the homework. I had been leaning towards the XOOM, and possibly the Toshiba, but this seems to fit the bill perfectly. Glad I didn't jump on any tablet, my gut had been telling me to hold off until more choices became available. I REALLY like the power requirements. On the hook you'll have apparently unlimited Entertainment running off the house battery with that adapter. While the XOOM could have done it, TOSHIBA needs a whopping 19VDC in! FWIW, with on-board GPS that includes chartplotter, 2 handhelds and a VHF/GPS handheld too Navigation will really play 2nd duty. Primary duty is really entertainment while on the aforementioned hook, so I was looking more at the 10" screens, but I think I can overlook that in favor to the pro's of the Dropad. I'm gonna head out and see if I can find one at a local seller to see one in action. Then I'll most likely go for it.

Also, I use PolarNavy, and it's my understanding that Steve will eventually port it to Android Operating System as opposed to Apple's iOS. So any Apple device is not a preference here.

Great post.

Being at the helm with these units. My Primary Question is Weather? Beautiful day its in a lot of sun and in bad weather it could be subjected to a lot of water..
Maybe not an issue where some are sailing.. but IMHO I often need to know where I am at, at the moment.. Is all this stuff weather proof??
I am not a geek guy at all, but If it will save me the cost of a New Bigger ( I have a 545 Garmin) 745 Garmin... I could learn.. :)

A ziplock sandwich bag can do pretty well too in a pinch. One drop of water tends to make my screen unusable. I did use my android phone with the navionics plotter software in Key Largo and it worked great. Software was $14 with the entire US east coast maps! I already own the phone.

I just keep my tablet in a ziplock freezer bag. The capacitive touch screens work right though the bag. I also keep my phone in a snack sized bag in my pocket when I'm on the water. A small piece of scotch tape on the bag keeps the bag tight so it's not at all annoying, and for about ten cents you protect your phone from those times the ramp where you forgot your phone was in your pocket before you marched in to manhandle something.

I bought the Admiral a "Nook color" from Barnes & Noble for around $225. It uses Andriod and can be upgraded with a $30. (ebay) memory stick to add features and make it very useable for APPS. It seems to be very readable in the sunlight, unlike my Android HTC phone which is useless outdoors in daytime. I have a bunch of great, free sailing APPs on my phone, but have to go below to see them.

I used my older laptop and seaclear charts as a plotter. I have not found Seaclear to be user friendly and it seems I have to re-learn how to use it every time.

I have a Garmin 295 aviation GPS at the helm now (used around $400.) it works very well in the sunlight and keeps a very nice triplog. I don't know if there is a way to implement a nautical chart on it, but that would make it real handy. Anyone have any ideas if the chart can be changed?

Seapup, very nice! A beautiful post on a subject I'm currently very interested in!

I'm running my old Dell laptop with a GPS puck and the low cost Polar Navy chartplotting software. It's a bit of a power hog and not speedy enough to double as a hi/def entertainment system, but good enough for my NMEA 2000 monitoring and web/e-mail use when in a hot spot. That will be rectified in the near future when this base hardware gets updated. Being a retired computer dude I'm now looking at a usb powered touch screen that I can extend onto the cockpit binnacle.
http://www.mimomonitors.com/products/im ... en-monitor
Ideally I would like to use two or three of these in an 'extended' desktop mode, to maximize the presented information (engine monitoring, sonar, charting etc.) but I suspect the daylight resiliency is not outstanding and will soon just try out one for evaluation purposes. I suppose it wouldn't be too hard to close fit a spray proof housing that could incorporate some kind of a sunshade. Windows 7 and the next ver. 8 are optimized for using a touch interface and definately point the way to the future. Overall power consumption is not too great a concern if the boat is rigged for extended cruising with high output silicon and batteries.
You have a tremendous advantage stateside in openly available digital maps, while here in Canada things get a little more restricted, and pricey. My cheapness keeps my progress slower in this area (Canadian inland waterways) though sooner or later I will have to decide on a choice of preferred supplier and bite the bullet.I'm going to examine your mentioned sources to see if it's possible to improve on what I've currently acquired. I have a Garmin 76C as a backup but find the PC based solution a very flexible solution to the vastly overpriced dedicated hardware market.
I think the next generation of global gps systems (galileo?), currently being launched, is soon going to be incorporated into the next productions of antennas/pucks to again raise the bar on position resolution.

Thanks .... Ross :)

I know you were ahead of the curve setting your ships computer up and it works well for you. The tablet works OK if you are starting fresh, but is not what you are looking for. In sun it is still not as good as a real plotter and still vulnerable. It is 100x better than my netbook though.

I don't think you will find one local, they are chinese labeled which is why they are cheap. From what I could find the dropad, also called herotabs and many other names got great reviews. (The A8X is the newest with GPS) They are rumored to be a chinese market samsung galaxy. http://news.softpedia.com/news/Samsung- ... 8770.shtml It is fun for when you get trapped inside to have plenty of music, videos and games.

The freezer bag trick works OK, the battery last long enough so there are no wires coming out of the bag and the capacitive screen works fine. For rough weather I would still recommend a real marine unit and not have it out. Eventually I am sure a line, boathook, foot, flying jack russell terrier or something will destroy it. It is not a replacement for a real plotter, but does most for a fraction the cost. Mac sailor tradeoffs :P

You have had that GPS a minute huh? :wink: I have one also I bought used back in 2004 off a pilot because I wanted a color GPS. I am not sure if any nautical charts will work on it. If you email garmin they always respond very promptly though.

I did find something that may be interesting to garmin users but have not tried yet. Flytomap http://www.flytomap.com/ftm/ViewMaps.as ... =Watermaps claims all of its maps are compatible with garmin devices and at under $5 they are a heck of a lot cheaper than garmin bluechart. When I get a chance I will try copying the chesapeake files to one of my handhelds micro cards to see if it actually works.

Hey Ross, What you are envisioning would be quite impressive.

Touchscreen was what I was initially thinking too since I already had the laptop and gps. I watched a few go quite reasonable on ebay. I did not need the NMEA interface for the motor so didn’t go that way though.

It wouldn't have been touchscreen or an input, but I was also thinking of picking up a 7" vizio led tv (supposed to be decent in sun) and connecting it to the video out of my laptop. That way I could keep the computer inside and have an outside monitor that would double as a tv tuner for the evening weather/news.
