If you are currently looking for a GPS watch and are set on a Garmin Forerunner then you are probably looking to get the best watch for your money. Garmin has many great models to choose from such as the Forerunner 305, 405 and 205.
Out of the three the least expensive is the Forerunner 205 so if money is your main concern then this is the watch for you. You can get it for about $140 at the time of writing this article. It has great signal reception and usability but lacks Mac and heart rate monitor support.
On the other end of the spectrum is the Forerunner 405 which costs about twice the price of the 205 at $270. It is compact and light making it great for those that want a GPS watch that can be worn in everyday life. It has Mac and heart rate monitor support but has poor signal reception and is less usable because it has a touch bezel which can be difficult to use.
The Forerunner 305 is a great value as it is packed with features and sold for a little more than the 205 at $175. It is the same size as the 205 and slightly larger and heavier than the 405. It has a heart rate monitor and support for a foot pod and cadences sensor for bicyclists. It also has the ability to display 4 data fields compared to 3 for the 405. Like the 405 it also has Mac support.
If you are someone who is on a very tight budget then the Forerunner 205 is definitely the way to go. On the other hand if you have a few hundred to spend and size and weight are an important factor for you then go with the Forerunner 405. For everyone else the Garmin Forerunner 305 highly recommended and is arguable the best GPS watch on the market and is highly recommended.
