What is WAAS?
GPS receivers have an accuracy of about 15 meters, but you can get to as close as 3 meters with a WAAS-enabled receiver. WAAS stands for Wide Area Augmentation System, which is a network of satellites and ground stations (in North America) that were designed to improve the accuracy and ensure the integrity of information coming from GPS satellites. Originally implemented by the FAA for aviation use, WAAS is particularly useful for serious outdoors enthusiasts as well as for precise in-city navigation.

1.0 out of 5 stars 4 of 5 reviews were right..., December 27, 2004

Matt (Bay Area) - See all my reviews

This review is from: Cobra GPS 100 1.1-Inch Portable GPS Navigator (Electronics)

First let me say that I'm not one of those GPS users who expects to have a signal everywhere I go. After all, these satellites are miles above the earth floating in space! So while I expect to lose signals every now and then I don't expect to never receive them.

My unit had some trouble picking up a satellite for the first time. The manual said 50 seconds but I waited a good 5 minutes. The manual also says something like it shouldn't take more than 35 seconds to receive a signal if it's cold, or 20 seconds if it's warm. I waited minutes everytime I turned it on.

When I did get a signal, the data seemed to be very skewed. I walked 30 feet across my flat backyard and it said I dropped 20+ feet in elevation. It lost it's signal pretty often. Then, about 5 minutes later, the unit crashed. Like a computer. The whole unit was frozen, backlight on, and a huge line across the screen. No matter what button I pushed the screen wouldn't change. So I tried to turn it off, but even the power button wouldn't turn it off. I had to take out the batteries.

Ok, beginner's bad luck. I reinstalled the batteries (which were new at the time!) and tried again. After 5 minutes of waiting for reception, the unit crashed once more in the exact same manner it had 20 minutes before that. I decided then and there to return it. If this thing has trouble finding a signal, let alone keep from crashing, then I can't trust it to get me where I need to go in the backcountry.

To be fair, I tested the unit on a calm, slightly overcast night with the temperature in the mid 40's F. I think they would be nice test conditions for any unit.

I returned it for a Garmin eTrex Venture for a few dollars more and am much happier with it. It even held a signal in the same conditions that I tested the Cobra GPS 100 in.

My advice: go with a brand you trust like Garmin or Magellan.

1.0 out of 5 stars GPS loses signal and cannot reacquire, April 22, 2004

By A Customer

This review is from: Cobra GPS 100 1.1-Inch Portable GPS Navigator (Electronics)

This is one of the worst GPS units I have used. The keys are not intuitive, the battery cover does not fit correctly (how can it be IPX7 water resistant compliant as advertised?), the unit loses GPS lock, when GPS lock is lost it cannot reacquire it.

The screens are nice in that you can configure the information, but the unit is not as flexible as say a Magellan Meridian.

1.0 out of 5 stars Cobra GPS 100: only good as a paperweight, July 8, 2004

By A Customer

This review is from: Cobra GPS 100 1.1-Inch Portable GPS Navigator (Electronics)

This unit can almost never lock onto a satelite. When it does it is innaccurate. I am returning it.
