There are a couple models which make up the Adventurer series for Memory Map, the 2800 model and 3500 model. They both stand out from the crowd and are distinctive with a bright yellow covering. The difference between the two is that the 2800 model is slightly smaller and more rectangular than the more square 3500 model. Some people might prefer the smaller one to put in a rucksack whereas the larger 3500 has more features and has a handy stylus option. Both of these handheld GPS devices run off a 50 channel high sensitivity GPS receiver which is outstanding in terms of the lock on and the power of the signal.

As I said at the outset, the main big plus for me in today’s GPS is the mapping options around and that’s why I’m a big fan of the Adventurer 2800 and 3500 models. The gold standard of mapping in the UK and further afield is for me the Ordnance Survey, a range of maps which give you every single road, track, building, natural feature and contour in beautiful colour and with shaded relief. And the Memory Map Series runs off the Landranger and Explorer versions of the OS maps so you’re guaranteed to have excellent mapping awareness on-screen.

The Memory Map Adventurer series 2800 model and 3500 model operate via a touchscreen interface. The 3500 model is slightly more expensive and comes with a handy stylus option for those days when your hands are cold and you are wearing gloves. The screen for both models is a high resolution 96,000 pixels. The screen size itself measures 2.8 inches and 3.5 inches for the 2800 model and 3500 model respectively. The latter also has the capability for Marine charts for those of you who want to use GPS while out on the water.

The Memory Map Adventurer series usually come with some sort of preloaded mapping, but you would need to check your GPS on purchase. However, the Memory Map V5 collection has plenty of mapping options available for the purchase. You just select which area you want to navigate in and download the relevant map. Both models have the addition of PC software which you can use in conjunction with your GPS unit. This allows you to store data, plan routes and analyse your trips between the PC and the GPS.

You can go on and on about the features of any modern handheld GPS these days but if there is one thing to take away from this article it is this: the Memory Map Adventurer series is strong in the area of mapping, something which I consider absolutely crucial in a quality GPS. Good quality and accurate rendering of a digital map is essential for your navigating experience and Memory Map will not let you down in this aspect.

There’s much more on popular GPS like the Garmin Oregon 450T GPS and the Garmin Oregon 550T GPS at these links.

In the late 1950s Sputnik became the first ever satellite to orbit the Earth. Again it was American researchers that quickly realised the theoretical usefulness of the satellite in terms of navigational purposes. They calculated, using the Doppler effect, that the radio frequencies of the approaching and departing satellite could be calculated in order to give an exact positioning of the object. Also because the object was 11,000 miles above the Earth its trajectory could be predicted incredibly accurately. With growing knowledge the US military developed its own satellite navigation system in the 1960s and called it the Transit System. Satellites were put into orbit around the poles, and nuclear submarines carrying the Polaris nuclear deterrent were able to take the signals in order to calculate their position beneath the waves.

The Navstar system had its inception following meetings at the Pentagon in the early 1970s. The idea was to improve on the current imperfect system of GPS by having 24 satellites built, each with four atomic clocks to ensure their complete accuracy in terms of time and position in orbit. The satellites, built by Rockwell International, were launched in a way that at any one time at least four satellites covered any given area on the earth. Each satellite would emit a continuous digital radio signal revealing time and position accurate to a billionth of a second. A receiver on earth was able to receive the satellite data and calculate its position on the planet’s surface.

So it was for the first time that somebody with a relatively simple quartz-powered satellite radio signal receiver could get their position accurately calculated by four satellites working in tandem. Careful monitoring from earth made sure the 24 satellites remained accurate in terms of their atomic clocks and their timings and positioning. This self same technology is the one we use today to power our Garmin, Satmap or Memory Map handheld devices; though born through military innovation and necessity today’s GPS happily can be put to more useful and peaceful means.

Nowadays of course we have the benefit of adventure and handheld GPS packed with handy navigational features. You can find zoom and pan, you’ll find barometers, altimeters, detailed mapping on full colour screen and loads of options to analyse your route before and after your trip. Thanks to rapid advances in science and technology those early innovations have given rise to a fantastic range of GPS available for today’s outdoors enthusiast.

That said, there are some great handheld GPS units. Garmin makes a wide variety of them, and Magellan is quite competitive too. Some of the well-liked units include the Garmin Oregon, the Garmin Dakota, the Magellan Explorer, and the GPSMAP series of handheld GPS units.

If you on the lookout for a handheld GPS unit, it might be wise to do a little bit of research so as to determine which GPS would be the best for you. You should generally consider what you need to use it for, and what features are important to you. User reviews are a brilliant source of data because, while manufacturer directions and promotional articles are educational, they don't seem to be unbiased. User reviews are much more likely to identify the weaknesses and strengths of the unit, which might be important to you and the way you wish to use it.

It's also a good idea to study up on the way to use the GPS unit you select. While using automobile GPS is rather intuitive, a handheld GPS might need some practice. This is because you do not have the familiar map with which to orient yourself. However with a little bit of practice, a handheld GPS isn't that tough to use. In truth the abilities required of Daniel Boone and Davey Crockett were far more difficult and tougher to learn.

So if you'd like to become New Age Davey Crockett and grab yourself a handheld GPS unit and start practicing. Good luck!

Ron Crockett loves the outdoors and sports. He also loves gadgets and likes to write about these, wishing that others will find them engaging. Some of his favourites include golf GPS units, motorbike GPS units, and tablet Computers like the Samsung GalaxyGalaxy Tab.

What are the ways in which mapping add-ons work with adventure GPS? Well, there are a couple of ways in which you can generate maps on screen. Each system and manufacturer has different ways of doing it but there are certain commonalities. Units like the excellent Satmap Active 10 Plus have the maps generated by SD cards which are plugged into the side of the system. Units like Garmin and Memory Map use Micro SD cards in some cases. Also with a manufacturer such as Garmin they have a wide range of mapping add-ons which you can download straight your GPS device.

Firstly, let’s examine the Satmap Active 10 Plus, a system which runs off SD cards. Satmap as a company offered digital SD mapping cards which cover the UK, Ireland, most of western Europe, Australasia and the eastern seaboard and the western seaboard of the USA. Easy-to-use, the SD cards plugged into the side of the device, and it immediately generates a digital image of your surroundings. You can pan, zoom, and really get to know your surroundings using features. The Satmap Active 10 Plus has won numerous awards citing the quality of its mapping and its ease of use in the field.

Garmin has one of the best ranges of mapping available to any adventure GPS. Because of its size and power and expertise in GPS as a company, it’s no surprise that their mapping downloads are exhaustive in quantity and superb in detail. Although you can run certain devices from Micro SD cards, the main strength of Garmin comes from their mapping downloads website, where there are literally hundreds of options to choose from. You can choose a large area, such as the GB Discoverer range or you can go for something smaller, using the Birdseye Select range, a handy feature which allows you to obtain a smaller section of mapping for a lower price.

Finally it’s worth mentioning the Memory Map Adventurer series of handheld GPS. The Memory Map Adventurer 2800 runs from Micro SD cards which render OS style mapping beautifully on the screen. You can get full Great Britain coverage on a scale of 1:50,000, and also individual mapping options are available on the Memory Map collection available from the website.

In conclusion I hope to have shown you that it’s really important to look at the quality and the availability of mapping before purchasing a handheld GPS. Really your whole experience while navigating in the great outdoors depends on having a decent quality map with an appropriate scale for your needs. Do make sure that you have done your research and you’ll find exploration so much more pleasurable and fun.

For people who enjoy sailing and fishing in areas where there are lots of fish, Handheld Marine GPS units are ideal. Fishermen find the pinpoint feature that many of these devices have that shows you exactly where the fish are gathered which helps in making your fishing expedition more enjoyable. The devices are waterproof so there is no fear of it becoming damaged should it get wet.

If you do not own a boat and only go fishing or boating by renting a boat, then you probably do not need a very advanced handheld marine gps system. However, a smaller unit that is handheld would probably be helpful to you to chart your course as well as one with the ability to track where the fish are and how big they are.

Sports technology in general has taken on a life of its own because as technology has advanced in other areas, so it has made massive advances with devices such as GPS systems for both land and marine. However, all sports both on land and water have been influenced by technology, and continue to improve to make sports of all kinds more enjoyable and more competitive.

Twenty years ago both land and water sports were rather basic. The only thing a person could depend upon was their own abilities. For professional or competitive fishermen this was often time consuming and disappointing because they had no way of determining where the fish were gathered. GPS systems designed for marine use has taken care of that problem making the whole fishing experience that much more enjoyable.

Choosing to make use of the advancements in sports technology is up to you. It does not really matter if your sport of choice is on or in the water, or on land, a GPS system can make it a far more richly rewarding experience, as well as making it safer for you.

Jashua Moses is involved with a Sports GPS Review website that informs his readers about the different styles of Handheld Marine GPS available.

Wireless

Today it is possible to find GPS systems such as the Garmin Oregon 400t that are able to access necessary information such as maps wirelessly. The system will provide you with the right information for you to navigate your way to a waypoint, or to find or follow a track or route, etc and this is a very necessary aid to anyone who enjoys exploring mountainous or wooded areas. Although there are units that have voice navigation they do tend to cost a bit more.

Once you have accessed the necessary information you would be able to share it with your hiking companions and that will serve to make the exploration you are all enjoying a lot safer and virtually worry-free.

Know Just What Your Location Is

If you are going to be traveling in rocky, mountainous or just unfamiliar terrain, it’s important to know where you are at all times. There are some GPS systems, much like the aforementioned Garmin Oregon 400t that will let you know your exact coordinates, even if you are under the cover of tall trees or inside a deep cavern.

Built-In Maps

Another great aspect of most GPS systems is that they come with many maps already built in. That means that, in most cases, you can find your way to any destination right out of the packaging. However, you may find that some maps have been updated since you purchased your device or that new maps have been created. These can be downloaded later on to make sure that your Garmin Oregon 400t or other GPS device has the most up to date maps possible.

3-D Maps

3-D maps are very handy for people who tend to hike in particularly mountainous areas so you would need to determine if the unit you are interested in supports that feature. Because these types of units make navigating so much easier by allowing you to see the terrain before you actually encounter it, thereby affording you the opportunity to find a detour if necessary, they are naturally very useful to the hiker.

If you are going to be exploring the mountains, or even if you’re going to be under the cover of dense forest, you will want to get a GPS system like the Garmin Oregon 400t. The right GPS system will make exploring extremely fun and safe. Not only will know you know what’s coming so that you can plan ahead of time, you’ll always know where you’re at allowing you to have complete control over your hiking adventure.

Jashua Moses volunteers with a Sports GPS Review Site that informs consumers about the different kinds of Garmin Oregon 400t and much more.

All the way through the 90′s the Garmin handheld receivers were common with the military in Kuwait and Saudi Arabia and was employed for the duration of the 1991 Gulf War. With the wonderful results in the military Garmin determined to branch out to the civilian existence, generating numerous products for the outside-gentleman in the late 90′s. In 1998 the eTrex was produced. A compact, lightweight, water resistant GPS unit that backpackers, hikers, and campers could provide to remote regions to make sure safety. This also came with the stunning 22 hours of battery daily life off of just two AA sized batteries.

Now that we see that the Garmin GPS is a actual good quality brand that the military couldn’t get ample of, let’s break down what features are available in the eTrex line, and which ones you want to pay out for, and which types you may well not require. Let us start with the screen. This is an aesthetic feature as properly as a useful characteristic. You can get an LCD screen in a four degree grey (black and white basically) or a 256 shade display. The functional characteristic is you will have various colours that correspond with different area’s of terrain this sort of as the trail, the grass/land, and h2o. This will support you recognize features that you are searching for as nicely as see what you need to have to see from the GPS a lot quicker. The aesthetic feature is that it just plain appears actually very good.

Another feature you might contemplate obtaining is the SD card accessible for use. With this you can grab routes and GPS places rapidly off the personal computer and load them up, as nicely as use this function to swap details with close friends, or help save distinct routes and GPS areas onto a separate drive. This can also be accomplished on the computer through a connector but an SD card is really convenient, so if looking into that feature it is likely to be purely centered on ease rather than necessity, unless of course you have 1000′s of routes you want to keep. Which brings me to the subsequent position, what form of connector do you want to use.

The USB is by far the ideal connector but the lower priced Garmin ETrex Handheld GPS units connect via a serial connector which is a bit of an outdated engineering and may possibly not be existing on the more recent computer systems, I’d undoubtedly advocate discovering one with a USB connector, they aren’t that significantly a lot more pricey. Most other attributes that the Garmin GPS has arrive normal with all models and can be simply checked with a quick browse of the product info.

If you are contemplating of getting your own Hand Held GPS, hitting this Hand Held GPS site will help you tremendously.
