[gps-talkusers] Re: lobalsat verses Royaltek receivers

Here's what I could find on all three receivers. One advantage to the Holux is that it has a slide switch to turn it on and off, which is a lot easier than pushing a button and guessing when the receiver comes on. I don't know if the other receivers have that feature or not.
The Holux also has built in WAAS, whereas you might find it difficult to activate in either of the other two receivers you mentioned. I'm not sure how important that is in reality, nor do I know if, once you activate WAAS in the other two receivers if it stays on, which would mean you wouldn't have to mess with it again.
By the way, there is already a Globalsat BT-339 which advertises faster acquisition time but has shorter battery life.
The RoyalTek RBT-2110 is the improved version of RBT-2010. This new version has been improved with the latest second-generation SiRF star III chipset (GSC3f).
The GSC3f delivers exceptional sensitivity and extremely fast time to first fix (TTFF). Besides, the RBT-2110 has a autonomy of up to 17 continuous hours 

with a new 1700mAh Li-Ion Battery.
The RBT 2110 is compatible with Bluetooth devices with SPP (Serial Port Profile) like PDA, Smart phone, Tablet PC and Notebook. It satisfies a wide variety

Holux Bluetooth GPS receiver
One of the strengths of Sendero's GPS is its ability to use the latest state-of-the-art commercial GPS receiver. This allows users to have the highest performance 

and accuracy rather than being tethered to a built-in receiver.

Holux GPSlim236 Bluetooth
New! Sendero introduces the smallest and most sensitive Bluetooth GPS receiver on the market and the only Sirf Star 3 receiver with a physical on/off switch. 

Meet Sendero's Holux GPSlim 236 Bluetooth GPS receiver.

Distinguishing Features of the new Sendero's Holux GPSlim 236:

. Small Size: 2.7 inches long, 1.9 inches wide and 0.8 inches thick
. Highest Sensitivity: Sendero's Holux uses the new SiRF Star III low power Architecture, which picks up satellite signals from inside a purse, vehicle
and even inside some buildings. Sendero's custom Holux is the only receiver with the extra WAAS satellites enabled by default, giving it the highest degree 

of sensitivity on the market.
. Accessible Power switch: Most GPS receivers have a power button, making it somewhat tricky for a blind user to know the on/off status. Sendero's Holux
has a tactile slide switch so it is easy to feel that up is On and down is Off.
. Custom Case: Sendero has created a leather and neoprene case to protect and conveniently house the little receiver. Besides the appropriate openings for
ports and the switch, the case has a clip and Velcro wings on the back for fastening the receiver to a shoulder strap.
. Accessible documentation: provided with all Sendero products including a Getting Started document for the Holux and a text version of the Holux manual.

Subject: [gps-talkusers] lobalsat verses Royaltek receivers



Hi all
I've been using the Earthmate serial gps receiver for a couple of years or so but now want to go to Bluetooth, I've enquire with Humanware here in UK and they're no longer distributing the Holux receiver which I see is still being promoted on the Sendero website. 

They have suggested the following two models:
 - Globalsat BT 338
- Royaltek RBT 2110
Have any users out there had experience of either of these receivers? I'd appreciate some comments before committing myself to one or the other, I've looked at the spec's for both and rather like the sound of the Royaltek what's your thoughts?
I use the gps with M'power daily in town and rural settings on foot, bus, train and by car. 

Kind regards Gavin and trusty Mr Nathan
