Garmin Edge 205 on 04/25/2007 02:38:42 MDT Report Post Print

Rating: 5 / 5

I will post a preliminary review now, and more details later in a long term review.

I bought the Garmin Edge to evaluate the SiRF III chipset; widely reviewed as being more accurate and sensitive to previous non SiRF models.
Since I bought this as an upgrade from my previous GPS, I will use this fact as the basis for my review.
I did a quick test from the comfort and relative safety of my apartment; 2nd floor, sky 60% obscured by buildings, atmospheric conditions: raining.

Basis for comparison is a 2005 Garmin Geko 101. They are similar in size, but the Edge weighs 78 grams, compared to the Geko's 87 grams.

Both units had previously fixed their position from a cold start. They were powered down, then up in this challenging location..

Time to first fix:
Geko; about 6 minutes
Edge; about 3 minutes

Stable position certainty:
Geko; about 76 meters (circular error probable)
Edge; about 17 meters

I then pulled the units indoors a few feet to really challenge the sensitivity of the receiving antenna. the Geko immediately lost signal; the Edge maintained 17 meter position certainty.

So, preliminary results are that the Edge, with SiRF, is faster to first fix, more accurate, and more sensitive. No surprises here.. that is exactly what other reviews are reporting.

Good news is that the Edge 205 can be had for less than $150. I got mine for $130 off ebay with an 18oz nalgene bottle included. (Because this is intended to be a bicycling GPS)

If I were comparing this unit with an 800 dollar topo mapping unit with SiRF, it would compare poorly; but considering the price point I give it a 5 as the best GPS for under $150.

A more detailed review to follow..faster fix
better precision
higher sensitivity
