Customer Review: Not great
I bought and used this plotter over the summer of 2008 in Maine. While better than nothing the screen is really too small to be useful. If you zoom out to get a range of a few miles, you lose chart detail. The screen keys on the cursor, and it can then be difficult to find the arrow indicating the boat position again. I would have returned it, but Amazon has only a 30 day return policy on unused items. So you buy it and try it, you own it. Unless you have a very small craft, buy a plotter with a larger screen.
Customer Review: Garmin GPSMAP 478
Fantastic. Easy to use both on and off the water. The auto-zoom is wonderful when driving. Worth every penny.

Now, with the help of technology, they can have a guide in their hands, which will help them to reach the exact location. Global Positioning System is a miniaturised version of Global Navigation Satellite System. The GPS uses a great deal of technology to make they owner reach the place for he is looking for comfortably. It’s officially known as NAVSTAR GPS. The GPS satellite constellation is managed and carried over by US Air Force.
The GPS works out by carefully timing the signals received through constellations of GPS satellites which are placed high above the earth.
GPS devices are composed of antennas tuned to the frequencies transmitted by these satellites. It also has a time calculator and receiver processors which perform the work of decoding.
One most extensively used GPS device is SATNAV GPS Navigations System which is Satellite Navigation System. These can be mainly found in the latest mobile devices.

GPS Navigation: a Smart Way to Search the Way
Finding The Way With GPS Navigation
Customer Review: OK...but far from perfect
While the features overall are pretty neat and this is a nice, compact design that is perfect for a night stand, I am finding that for a bedroom alarm clock it doesn't work so well. I thought that the "HiGlo(tm)" back-lighting was always on, making it easy enough to read in the dark, but that is not the case. The back lighting only comes on after fumbling to find one of the "touch technology" buttons that, of course, are also not lit up. For a desk clock, this would be perfect. For a bedside clock, find one that is visible in the dark...
For any of us who have been lost while driving, the road map has been our guiding light, identifying roadways and landmarks to help us find our way. But gone are the days of tri-folded paper maps that require the use of illumination and attention taken from the road. The modern Global Positioning System - or GPS - has transformed the process by which we find our way. But, contrary to popular belief, GPS navigation is not a new invention designed for strictly consumer use.
The Global Positioning System marked its beginnings in the 1970s but seeds of its existence were sown prior to that. We first saw the possibilities of satellite navigation with the launching of Sputnik in 1957. Russian scientists who were monitoring the progress of Sputnik found that they could track its movement based on radio waves; this set the foundation for GPS. The U.S. Navy used an elementary form of GPS in the 1960s when they used six satellites to help their submarines pinpoint their location. But GPS as we know it was designed and implemented by the U.S. Department of Defense in 1978 when they launched the first operational satellite.
Today, 24 satellites circle the earth and provide an enormous amount of information in terms of plotting location. A derivative of this technology in modern times has been GPS navigation - a system that allows drivers to map their routes. GPS navigation comes in a portable unit that can be removed and transferred from vehicle to vehicle when needed. But because of the growing popularity associated with this system, GPS navigation units are now mounted as standard equipment in newer cars. Of course, GPS navigation is also essential to water navigation as used by boats and ships.
But GPS navigation is not solely for the use of vehicles. Outdoor enthusiasts - with an eye towards safety - will often carry a hand-held GPS navigation device; the modern equivalent of a compass.
GPS navigation has allowed us to explore new terrain as we venture forth with confidence, knowing that, no matter what, we will find our way.

GPS Navigation and Mapping Software - Mapping the Way to the Future
Revolutionizing Business with GPS and Mapping Software
In the modern business world, operating internationally on a heretofore inconceivable level, finding geographical information that is easy to access, precise, and up to date has become an absolute necessity. In the past, many companies were managed from the world’s superpower economies, like the US, the UK, and Japan, while operating in distant countries, sometimes on the opposite side of the globe. There was less global competition for international companies and there were a lot of sure bets. Recently, however, the number of globally operated companies has expanded exponentially, with companies from China, India, Saudi Arabia, and other emerging nations buying business assets even in the US itself. This new competition has made the globe a volatile marketplace.
Managing companies on the other side of the planet, understanding conditions being experienced by your branches around the world, and getting a solid reading of potential future business opportunities has only gotten easier, however. With the development of three converging technological concepts, it has become possible to tailor interactive maps to the specific needs of these organizations. Three key technologies have made this possible: Global Positioning Systems (enabling the use of GPS Navigation Software), Geographic Information Systems (creating the mapping software used as the basis of so many navigational tools now), and Web Mapping (using GPS mapping software to create up to date maps for a variety of specific purposes).
Geographic information systems have actually been around for centuries. In its most literal form, it simple refers to a map that indicates the importance of certain objects and regions. They actually date back to caveman days, with map paintings on the wall, showing markets, borders, and points of interest. As the world has progressed in complexity, however, so, too, have geographic information systems, providing more elaborate details specific to the particular issues of importance at the time.

The accuracy and precision these devices these devices reflect are appreciable. Moreover, GPS Navigation devices are very affordable as well as stylish.
How to Buy Portable GPS Car Navigation Systems
I was researching for a portable gps car navigation system the other week because my job requires me to travel a lot in different cities.
It was just practical for me to get a portable system that I could carry around with me.
While most portable gps systems have basic functions such as voice narrations to help direct you where to go, it's worth the time to figure out exactly what other features you may need.
For example, there are some models which will tell you which lane to be in so you can make turns in high traffic streets more easily. This could come in handy if you're traveling in a congested city such as Chicago.
When considering the features that you want in your portable gps navigation system, it's important to consider if you'll actually be needing that feature or if it's just an added bonus.
Here are some things to consider:
Size of the GPS Unit
You can find pocket sized units which are very portable but have small screen sizes. If you want a larger screen the units will be less portable so make sure to consider how you will use your unit.
Price of GPS Unit
Cost is always at the top of everyone's minds when it comes to technology purchases. As with anything, you get what you pay for. Skimp on a low priced unit and you may just end up with something that functions half the time.
My brother-in-law spent $175 on a no-name brand GPS unit and after using it to help him move across the country, it took a permanent vacation.
You should also consider some of these other major features:
Street name announcement -
Does the voice narration announce the name of the street or does it just say next street?
Time to destination -
Will it calculate how long it will take you to arrive at your destination? This feature is invaluable when you want to know the closest destination out of several choices.
Automatic rerouting -
If you make a wrong turn, does your navigation system reroute you?
You'll find a lot of choices when purchasing a portable gps car navigation system. My suggestion would be to figure out what options you would like, then find the units which have those features and check the units out physically at your local electronics store.
You can then go online to find the best deals for your unit. Often times, I find the best deals online after viewing the units in a store.
As with most technology, you will find that in a few years there will be more GPS units with more features for lower prices.
I'm very excited to see this technology develop.
GPS and Other Emergency Contact Devices
What is the best kind of GPS system for you? This depends on what you intend to use it for.
Garmin 12 GPS is very good. There are various models of the 12, 12XL etc. They can be found for under $150. The altimeter is usually off but once you find your position, most of the time the map tells me what my altitude is. They have a pretty decent battery life since you rarely ever use your GPS for 12 hours straight.
The vendors selling GPS units are Garmin and Magellan, those are good brands and can meet your requirements quite well. There is a third player, Brunton (compass makers gone hi-tech). They make very reasonably priced GPS units with lots of bells and whistles. Garmin GPS records the distance travelled, speed, average speed, etc. Make sure you get good battery life and enough memory to be useful.
Mitac Mio 168 comes out well for my requirements but is more expensive, especially if you go for the tom tom mapping software too (voice directions when I'm out on my motorbike!)
Most of the functions on GPS of this sort you can get from a map. Maps on pure GPS are not as good as on a GPS/PDA but good maps for these are usually expensive. Some mountain rescue team members use PDAs with 1:25000 OS mapping data for recording search patterns etc.
You really need to look at your own plans - for instance, most backpackers use GPS to "confirm" their position, and they don't use it to set waypoints, determine compass direction, navigate, etc. Many backpackers use it as an emergency navigation tool in Utah's deep, narrow canyons, where a map and compass can be almost useless.
One word of warning, take very seriously the statement on the front of all GPS units "Do not rely on this unit as the primary source of your navigation." It's always a good idea to have a map and compass with you when engaging in wilderness travel and use them right along with the GPS. It can actually be kind of fun to see how accurate you are with a compass and compare map routes with GPS routes to see why you ended up going the way you did.
What are the numbers on a compass for and how do you use a compass? The numbers on the compass are for degrees or headings. They will tell you what direction to proceed on. The first thing you need to do is figure out what kind of compass you have, a floating dial or a floating needle.
As to emergency contact, you could buy an expensive Iridium/satellite phone - they can get a signal just like a GPS does. They run over $1,000. It may also be possible to rent one. For real emergencies, not simply a vehicle breakdown, there is a GPS signaling device, much like ONStar (GM trademark), that can send an emergency signal. The final thing to do is to check in at the local ranger station, BLM office, forest service visitor center, etc., and see about leaving your itinerary with them, as well as a promise to check-out with them when leaving. If you don't check in, they would send someone out to check on you.
Compare Garmin GPS Systems Before You Buy
GPS and Garmin have become synonymous. They are the leading GPS manufacturer in the world today by a long way. They started out in 1989 and today they have sold millions of GPS receivers.
So how do we know which Garmin GPS device will be perfect for our needs? There are so many which makes it very difficult to decide. The Garmin Nuvi and StreetPilot are some of the most popular GPS devices on the planet. Lets take a look at some of the automobile GPS systems and compare the differences.
Garmin StreetPilot 340
The Garmin StreetPilot c340 has a big advantage over the c330. That advantage is text converted to speech. Instead of GPS saying, turn right in 50 meters, it will say, turn right at Glover Street. This feature helps a lot when you dont want to look down at the device to confirm the street name.
Another great feature of the c340 is that it can easily be upgraded with an optional FM traffic receiver. What this means is that live traffic information can be sent to your GPS device to warn you of construction work, accidents etc. The StreetPilot c340 can then show you the way around the traffic and guide you to your destination.
Garmin Nuvi 250
The Nuvi 250 is famous for its simplicity. It doesnt have the advanced options most of us never use. So many buyers waste money on GPS systems that have features they will never use. They could have saved a lot of money and at the same time satisfy all there needs with a cheaper GPS system. If youre not the hard core type then the Garmin Nuvi 250 will be the perfect match for you.
The Garmin Nuvi 250 comes with a 3.5 inch display, which is the standard among the entry level GPS devices. 3.5 inch display is a big enough screen to find your way with ease. You can also insert a SD card if you would like to load additional products and maps.
The only feature the Nuvi 250 doesnt have is the text to speech feature I explained with the Garmin StreetPilot c340. Things like Bluetooth, MP3 player, FM transmitter and widescreen is not available on the Garmin Nuvi 250 but many will agree that its not necessary. If Garmin decided to include text to speech it would have been the perfect GPS system at entry level but if that doesnt bother you it might just be the one for you.
Discount Garmin GPS, Quality At A Great Price
Of the many various GPS manufactures, Garmin has become the most popular. Not only do they make a high-quality product, but they offer a wide variety of GPS units for average consumers, mariners and pilots. However, quality can come at a price, as some Garmin GPS units can range in price up to thousands of dollars. This is why it is important to try to find a source for discount Garmin GPS products if at all possible.
The first way one can try to find as source of discount Garmin GPS products is from the Garmin website itself, Garmin.com. The company website does not sell discount Garmin GPS directly; rather they provide a list of stores that do sell their equipment. They also provide access to refurbished GPS units that sell at greatly reduced prices. Refurbished units from authorized sellers come with a short warranty. Most refurbished Garmin GPS products are very reliable. Another option to finding a discount Garmin GPS unit is to check out the special offers on their website. Discount coupons are frequently available to many Garmin GPS products. To find Garmin retail stores, one has to make two selections: what country they are in and what type of GPS system they are looking for. The resulting hits will show information about the store including: address, telephone number, email address and a link if it is online. The potential buyer will have to search through the list to see which store offers the best discount Garmin GPS.
The second way one can locate a source of low priced Garmin GPS is from auction sites such as Ebay or Ubid. These sites work through a bidding system. Sellers post their items which contain a starting bid. The buyer places their bid and if they bid the highest after a number of days they have purchased the item. Auction sites also allow sellers to utilize the "buy it now" feature. Of course, "buy it now" tends to be more expensive in comparison to bidding, but it gives the seller an option to buy the item immediately. When the buyer is ready to pay, they can use their credit card or bank account through a payment system known as Paypal. Often using online auctions will provide the best prices for discount Garmin GPS products.
Another way you can buy a Garmin GPS at a reduce price is through shopping comparison sites, such as Froogle.com, Bizrate and Pricegrabber. Why would one even consider other methods of buying discount Garmin GPS if these options are available? It is because though these sites are very helpful, they do not always provide the match one might be looking for. Sometimes the results may not even be related to what one was looking for. Other times what they would consider a discount Garmin GPS would not necessarily be what the person searching would consider a 'discount Garmin GPS', since the prices could actually be those of regular retail Garmin GPS. This is a major downside when using shopping comparison sites, which is why one should be aware of the different sources of discount Garmin GPS units.
There are several methods for finding discount Garmin GPS products: through the Garmin website itself, auction sites or shopping comparison sites. Through these resources one can save hundreds, maybe even thousands of dollars on their next Garmin GPS unit. Purchasing a Garmin GPS at any price is a good investment. However, there should be no excuse why anyone should have to settle for a lesser quality GPS brand when you have access to discount Garmin GPS products.
