You are looking to buy a GPS tracking watch and wish to know who makes the best one. The solution to that could be simple, you can find only three well-known companies making them; Garmin, Timex and Suunto wireless charger manufacturer. That's not to imply there aren't other programs out there making cheap knock offs but we won't focus on them. Some might say "What about Casio? They are a well known company." That's true and they make some fine products nevertheless they no further produce a GPS watch to ensure that leaves Garmin, Timex and Suunto.

When taking a look at the models being provided by each company you will discover many different available features. I believe that it is important to say what these watches won't do since there could be some misconceptions out there. Many of us have, or have experienced a GPS system in a car or boat. These are really neat gadgets to own and can be quite a real time saver especially for people who travel extensively for work or pleasure. These units display your position on a map and may include landmarks like restaurants, gas stations, etc. GPS watches have tiny display screens so the mapping feature isn't practical. Neither is the voice feature show inform you when to show!

GPS tracking watches use satellites to pinpoint a position, then with continuing updates of the position, they display data for speed, distance, elevation and more, with regards to the model. Options might include a center rate monitor or cycling cadence tracker.

You could quickly see several important variations in the way the companies package their GPS watches. In all cases, the systems use a GPS receiver and a digital time piece to hold out the calculations. Being a watch each of them provide display of data in what appears to be always a wrist watch although sometimes quite large. The GPS receiver may be contained within the watch or, separately, strapped to the arm or even mounted on a belt. It will be wise to offer this matter some thought before creating a purchase. I would rather to truly have the watch and GPS receiver self contained and worn such as a traditional watch, but opinions vary.

Garmin has got the Forerunner 205, 305 and 405 which are all-in-one models, having the appearance of a digital wristwatch but of larger size. They also provide Forerunner 101 and 102 which use a Velcro strap around the wrist but have  the appearance more similar to wearing an iPod.

The Garmin line works on the receiver that is built-in and wraps around the wristband, a little, to keep it oriented to the sky for better reception. The units also incorporate a USB to fairly share data together with your PC. An A/C battery charger is employed to fill up the battery which generally provide about 8 to 10 hours of tracking use.

Timex has been making watches almost forever and has offered athletic oriented models for decades. Tri-athletes and Timex go way back. They use a separate watch / GPS receiver approach unlike Garmin. This does possess some advantages, including the ability to wear the watch everyday since it's small enough to be practical. When enough time arises you merely start and secure the separate GPS receiver and you're prepared to go. Timex also offers an almost endless variety of athletic watches.

The third manufacturer is Suunto which as you may guess offers several models. They often have the appearance resembling a normal digital wristwatch. The GPS receiver is contained in another wireless so the watch can remain very compact. Typical choices are; altimeter, barometer, countdown timers heart rate monitors etc.

The technology evolves continuously so smaller, cheaper models will likely become obtainable in the near future. It may also be interesting to see if other programs will join in and offer their very own line of GPS tracking watches.
