movingzachb Posted May 23, 2007 Share Posted May 23, 2007 I am shopping for a hand held GPS I have researched a bit on these forums and I have found that the Etrex Vista CX or the 60 is the probably the best way to go. I have realized that I am a stickler for signal and I read on about Quad Helix vs Patch antennas as well. I was trying to find specs on these units on weather or not they do have the SiRF III chipset. Not to say that since they just mention it is a highly sensitive one isn't as good. I really don't know but from what I know this SiRF III is the best way to go. So if someone knows for sure please let me know or what you know about the current highly sensitive chips these other ones have. Quote Link to comment
+imajeep Posted May 23, 2007 Share Posted May 23, 2007 Garmin GPSMAP 60 Csx has the SIRF III chipset, but the eTrex Vista Cx does not. Difference in reception is noticeable. With my Vista, I could only get a fix in a clearing. With my 60, I can get one just about anywhere. Quote Link to comment

Those with the SiRF III chip will be noted as having the "High-sensitivity receiver". Quote Link to comment

+apersson850 Posted May 23, 2007 Share Posted May 23, 2007 I've read rumors about that Garmin is abandoning the SiRFstar III chipset in future models. These would use a high-sensitivity chip from Mediatek instead. I don't know if it's true, though. But it would explain using the phrase "high-sensitivity receiver" without displaying the SiRF logo.

QuigleyJones Posted May 23, 2007 Share Posted May 23, 2007 If you can wait a few months the Etrex Vista HCx will be coming out and it has a high sensitivity chip. Quote Link to comment
+Miragee Posted May 23, 2007 Share Posted May 23, 2007 Also available in a quick-to-digest format in the Garmin FAQ that's pinned at the top of this thread. Since so few people seem to notice that, I wonder if the Font size on the Pinned Threads could be increased to, let's see, +5 and BOLDED. I wonder if that would help . . . Quote Link to comment
+JDandDD Posted May 23, 2007 Share Posted May 23, 2007 Yahoo finance has a report from March 1, 2007 indicating the Garmin had finished validating the chips and would begin placing orders with MediaTek 'in the first quarter" which means now. From what I can find these are A-GPS standard. There are a number of reports out there of a number of companies, also including Tom-Tom, who have been dropping Sirf company chips. Sirf is just being out performed on the power consumption and sensitivity sides, not to mention the smaller form factor of A-GPS. As well, these other manufacturers are selling their chips for a lower price (GPS on a single chip has a lot to do with that). There's a lot of price pressure in the market these days because of the choice so reducing the price of the core components makes lots of sense to Garmin. It would appear that Sirf got the head start on higher sensitivity chips but their technology and price points haven't kept up. JD Quote Link to comment
+Mtn Summit Posted May 24, 2007 Share Posted May 24, 2007 I have the 60csx. It has the Sirf III. I had used prior to my purchase a friends E-Trex without the Sirf - A HUGH difference. I do a lot of backpacking and would now not consider having a GPS without the SIRF. Quote Link to comment
+Prime Suspect Posted May 25, 2007 Share Posted May 25, 2007 But it would explain using the phrase "high-sensitivity receiver" without displaying the SiRF logo. They're still using the SiRF logo. They've just moved it, along with the other icons that used to be at the top of the page, to the bottom of the page. Quote Link to comment
