This manual is a complete user manual for Garmin handheld receivers. It covers theory and practical applications for gps technology and the receivers that use this technology. Representative products for all of the Garmin handheld receivers, past and present, are explained and tips are given on getting the most out of each model. It is designed to augment the user manuals that are supplied with each product but is complete enough to replace them. While this manual is Garmin specific it provides a basic understanding of gps devices that is applicable to any gps receiver. It was written over a period of 4 years and has been reviewed and tested by hundreds of users over that period. It has been used as the reference for training on gps usage. Because of its unique approach that develops the theory behind operation as well as specific details, it provides a basis that will allow a user to be able to use any gps receiver. Skills in the use of a gps will provide assurance and safety for the user.
Topics extend beyond just operating the unit to actually being able to use it for navigation on the land, in the sea, or in the air. Topics are applicable whether you are hiking or driving to your destination. These topics include product operation, waypoints, routes, tracklogs, navigation, maps and databases, product selection, features, theory, accessories, and product unique functions.

Why do I want more than 5 parallel channels
Are there any other reasons to track more than 4 at once?
Why aren't all units parallel?
So why 12 channels?

Communications plus GPS
Dale DePriest first became interested in GPS in 1996. He soon acquired a Garmin 38 and began a love affair with this technology that continues to this day. Early in his thirst for knowledge he found a news group titled sci.geo.satellite-nav where knowledgeable folks discussed this topic and the units that could perform the magic of gps. Since he had a engineering mind a background he felt he really needed to understand how these devices worked. A bit of reading and a lot of experimentation soon started revealing the secrets locked up in these handheld units. He started sharing the data he had found and providing some help to other users. This led to his connection with Joe Mehaffey via his web site and Dale’s contributions became articles on the web site joe.mehaffey.com (now called joe.mehaffey.us). New purchases of a Garmin12, later an emap and a vista, provided connections to the latest 12-channel technology. Receivers such as these really moved the gps into the main stream as a reliable navigation tool once you understood how it worked. As more users adopted this technology, Dale found that many questions were being asked over and over again which led to an idea of developing a manual on how a gps worked and more specifically how to use one. He started by adding articles to his and Joe’s web sites and, through the encouragement and feedback of readers, a manual started to form. Now, 4 years later, the baby has grown up and ready for the world. Dale continues to expand his knowledge and provide reviews on gps related software and hardware. Combining his gps passion with a new passion for handheld devices, he has built web sites for both palm users and pocketpc users, as well and continuing coverage of gps topics.
