How reliable is the Skytraq 44 Channel chipset (Holox 441 Model) in comparison to the Surf Star III chipset?

Are more channels better ?

I've never heard of either the chipset or the manufacturer! It sounds like it's a play on Holux who are a respected manufacturer but they use SiRFIII and MTK.

Do you have any links? I must say it all sounds rather dodgy to me!

The spec seems amazing but not sure if this is just a cheap architecture from the far east at a low price, with only 1 year warranty and which also has not been tested in Europe.

Can you advise if should just stick to the Surf Star III chipset for a reliable service in the UK/Europe as the Skytrak does not seem to be known chipset architecture.

Ok, well Skytraq is a new chipset although little is known about it and we've not had one that uses it to test.

The one you link to appears to be a re-badge of the Wonde Proud GPS-BT100Y device, see here.

I can't say much more, it's a new but little known chipset that is allesged to be equivalent to the SiRFIII, Hammerhead and MTK alternatives. without testing I wouldn't be able to comment further although at £17 it's got to be worth a chance!

I posted this on another thread before I read this thread...

"I have had a Holox BT-441 for about a month now.
Its performance is pretty awesome in terms of first fix, reaquisition and finding fixes inside heavily shielded buildings.
My GPS info regularly reports 9+ sats!
I have however had a few problems with charging it but I suspect that is due to my attempting to use the chargers supplied with my Holux GPSlim 236 which also has a mini usb port.
My in-car charger blew completely!
Anyone any clues on this?
Anyway, as it takes the standard nokia 3.7v battery (like the 236), and lasts for about 10 hrs on a charge that hasn't been a problem.
I am very pleased with mine at the price I paid (about £33 inc p&p ex ebay)"

It outperforms the sirf111 in my Holux236 very considerably in most(all?) aspects
