eTrex GPS Rugged Handheld GPS

eTrex GPS

The Etrex 20 is a nice step up from the Legend H. Satellite reception is very sensitive. I compared the Etrex 20 head to head with the Magellan GC...The Etrex 20 locked on to 18 satellites under a sky with no obstacles vs. the 5 locked on by the Magellan GC. The Etrex was showing an accuracy of 7 feet (Glonass satellite constellation added to U.S. + WAAS and European satellites allows for this type of accuracy) while the Magellan GC was showing 56 feet. Inside a building next to a window, the Etrex 20 found 14 satellites. The Magellan GC was unable to find any satellites.

The aquisition of satellites is quite fast. From a cold start out of the box, the Etrex 20 found my location in about 30 seconds. Once the unit has found it's location, subsequent aquisition times (given that one hasn't traveled several hundred miles since last turning it on) is almost immediate.

Garmin tech on the phone helped me put my identification on the start up screen.

The unit allows for one to choose the order that screens come up... I liked the Legend H's progression of boot up screen into satellite screen into map screen...I have set my unit to power up on the satellite screen, and then when I am satisfied with the satellites that have been found, pressing the back button puts me into the map screen. Pushing back again gets me into the menu screen.

The basemap is worldwide in scope for major highways (the Legend covered North and South America as far as major highways are concerned. The rest of the world consisted of primitive outlines of countries, no highways, only capital cities), and the coverage of towns and cities around the world is impressive. I looked for the little city of Turfan in the Gobi Desert of northwest China on the old silk route and found it!

eTrex Presumably atypically

eTrex Presumably atypically Presumably atypically I use eTrex units nearly exclusively for road navigation and often calculate long routes. I've used a Legend Cx extensively and it's showing its age so I was glad to see the introduction of the 20. I toyed with buying a Nuvi but don't care for the design as it lacks configurability and water resistance, uses a touchscreen, doesn't lend itself well to a motorcycle or kayak or walking when you want to walk. The Legend Cx routinely takes several minutes to calculate in addition to slow map `drawing' times and I'm pleased to note Garmin improved calculating speed significantly. I used the two side by side for quite a while and the 20 calculates in roughly 1/3 the time (still noticeably slower than the Nuvis I've used). Additionally the map drawing time is much reduced. eTrex Presumably atypically Satellite acquisition and retention is quite a bit better: if you turn on both simultaneously the...

Tracki GPS Tracker for Vehicles

Easy Navigation in the Woods or on the Water with the Garmin eTrex GPS Handheld Tracki GPS Tracker for Vehicles 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 ...

Automatic Identification System, AIS - The Best Navigation Aid to Boaters Since the GPS

Automatic Identification System, AIS - The Best Navigation Aid to Boaters Since the GPS One of the fastest and biggest growth areas in marine navigation is AIS. Having a AIS transmitter unit onboard, will turn your boat into a radio beacon continuously transmitting speed and course and your identity. Conversely having an AIS receiver allows you to track a ships, COG, SOG when in VHF range. This can be very important information for navigating in shipping lanes and channels. What is AIS? AIS stands for Automated Identity System. The identity is the transmitting vessels MMSI number, current speed and course which are just some of the information you can get. AIS has been developed to help prevent collisions between commercial shipping. AIS has been a legal requirement on ships over 300GT for a while. In US waters it is required by commercial ships over 65ft and tugs over 26ft and over 600 HP. Vessels with the proper equipment can receive/send the AIS signal over a special ...
