I am an expert navigator with a map & compass but neither is as effective or as easy as the eTrex.

I highly recommend the Gramin eTrex as a basic navigational aide. It’s also a great starter for learning about GPS systems. It does everything it’s meant to and does it very well.

Garmin’s claims of one handed usage are for real, it is easy to navigate the interface with the solid buttons on the unit.”

The Garmin eTrex GPS has one of the longest battery lives on the market, another major influence to purchase, and because it is only powered by two AA batteries, the maintenance costs are minimal. I highly recommend the Garmin eTrex GPS to users of any skill looking for a quick, reliable and inexpensive GPS fix.

Nothing fancy about this unit — other than the remarkably easy to use interface. Its not possible to do better in this price range.

The Garmin eTrex GPS works well (superbly well) for the sea kayaker. It’s waterproof. You can pre-plot a destination if you know the coordinates. You simply utilize the “go to” feature and the eTrex points the way.

Like most modern hand-held units, the eTrex generates its own map of your movements as a visual tracklog or ‘breadcrumb trail’. For retracing your steps (’Trackback’ mode) you will see all the detail you will ever need.

New technologies in micro satellites are moving very fast as processors, sensors and systems get more powerful and much smaller. I propose to have these systems and micro satellites to be in a solar system type configuration as they fly, spinning around each other with each small micro satellite literally connected to another and spinning around a center satellite module connected to a few of the orbiting micro satellites.

The Lines holding them together will also be an entergy tail, that is to say it collects electromagnetic energy to keep the small communication system in low orbit, which takes a lot more energy, but there is significant electromagnetic energy there as well.

Why Low orbit? Well it allows for listen devices to be quite robust in ability and cuts down on the delay of communication time from Geo Sync Satellites. Perfect for the Military, NSA or commercial applications. Smaller satellites also have a reduced risk or the chance of collision by orbiting space junk and in low orbit there will be little if any of this orbiting high-speed debris.

By putting these units on tethers then will know where each one is and be able to be a single point of eight-point or Octa-angulation for precise GPS needs. Additionally they could be as far as 100-meters apart and operate net-centric or together, meaning you cannot see them, too small, you cannot shoot down what you cannot see and you have a massive communication and world class GPS system, as well as a spy listening device. Think on this.

Anyone that enjoys the great outdoors has probably heard of GPS devices. They can come in handy when you are hiking, boating, biking, or doing just about anything else in the great outdoors. Twenty years ago, you had to rely on a compass the position of the sun and stars and your own common sense. Not anymore! Now you can have a handy little device that can pinpoint your exact location at any given time of day.

If you are in the market for a GPS device, it is important that you understand how it works. Since the GPS devices rely on air signals, you must have a GPS receiver and a clear view of the sky for them to work. When your device is turned on it is actually linking up with 27 orbital satellites in place around the planet. Four of the nearest satellites are located and the distance from them to you is calculated via the hand held device. The process is called trilateration. Based on that, the GPS device can determine where you are on the planet. Pretty neat huh?

When you look at the different types of GPS devices out there, you may wonder which one is right for you. Prices can range from $100- 5000 dollars, so it is important to do your homework. Find out what features each device has, and determine whether you need them or not. The following is a list of tips to get you started when you are shopping.

- Research the name brand. Though GPS technology is fairly new, the manufacturer should have a long track record of creating quality electronics.

- Don’t buy the cheapest or the most expensive GPS device out there. The cheapest may not meet your expectations and the most expensive one probably has too much extra stuff you will never use.

- Look for a large display, lighted if you are going to be traveling at night.

- If you plan on traveling by foot look for a model that is lightweight, and water resistant.

Once you decide on a model that you are interested in, head over to your local sports supply store. Get prices on the model above and below it for a good range. You can also try to look at auction sites like Ebay.com to find a good deal. If you are lucky enough to find one that is used, make sure to test it out first to make sure that it works properly.

Deciding to buy a GPS system is a personal one, so make sure that you understand the ins and outs of the technology. If you do a variety of different activities a good basic, waterproof model will do the trick. If you have friends or family members that own a GPS system, ask them if they are happy with their purchase. That way you can get an honest opinion on the different brands out there. An online opinion site like epinions.com is also a great place for honest answers.
