Garmin Adds High Sensitivity GPS Receiver to eTrex® Series

I must have spent too much time analyzing engineering requirements, because this claim does not impress me. And I own 4 Garmin GPSs so I'm not critical of the products. But how much more sensitive? 0.00001%? And in what conditions? Couldn't find the answers on garmin.com.
I'm too young to be a curmudgeon but these vague 'better' claims just don't blow my hair back nor make me want to buy a 5th Garmin (incidentally, 2 are for sale on ebay :)

I'm pretty sure that Garmin's definition of "high sensistivity receiver" is the SiRFstar III chip. I think the two are equivalent in Garmin's marketing terms.

That said, on http://www.sirf.com I note that there are 3 different chips using the "SiRFstar III architecture".

FWIW :)

From the Garmin site: "Deep foliage, nor canyons phase (sic) the rugged eTrex Vista HCx. Its high-sensitivity receiver holds a GPS signal in the toughest environments."

These new units may or may not be using SiRF chipsets, but that's not important if the performance is as good. I doubt that market-leading Garmin would make a statement like this if it weren't true. Interestingly, all verbal references to SiRF technology seem to have been removed from the Garmin website.

Now for $160 less than the cost of a 60CSx, the Vista HCx offers almost equivalent features and performance and with a weight savings of 2 oz and better battery life. All you give up is tide tables and a bit of screen area.

(shouldn't that be "faze"?? :)
