Uh this is difficult as I bought it without actually reading the label. There are two options from Caretec. I think. One is about three hundred pounds and the other is about 60 pounds. You want the cheaper option. It discriminates about 200 colors and has a light detector. The more expensive version has a lot more colors but is so scientific it's over the top. The unit I have is about the size of a mini tape recorder and has two buttons on the side. The top one is the colour detector the lower one is the light detector. Place the top of the unit against a surface and click the button and it tells you the colour. For example my shirt is a dark red and it tells me 'brown red' which is a fair enough description really. If I press the lower button and hold it in I can scan around and locate the little LED lights on various devices. The sound is a tone that gets higher the more light there is. Obviously if the light flashes then the tone warbles. The only thing missing is a way of making the aperture smaller which used to be a feature of the old RNIB detector but in practice that hasn't been much of a problem. - Liam -----Original Message----- From: gps-talkusers-bounce@xxxxxxxxxxxxx [mailto:gps-talkusers-bounce@xxxxxxxxxxxxx] On Behalf Of G B Sent: 23 July 2005 15:33 To: gps-talkusers@xxxxxxxxxxxxx Subject: [gps-talkusers] Re: receivers Liam, Which one of the caretec devices do you use to tell the lights on for a receiver? thanks -----Original Message----- From: gps-talkusers-bounce@xxxxxxxxxxxxx [mailto:gps-talkusers-bounce@xxxxxxxxxxxxx] On Behalf Of liam Sent: Saturday, July 23, 2005 01:43 To: gps-talkusers@xxxxxxxxxxxxx Subject: [gps-talkusers] Re: receivers Richard, Caretec make the light probe. It's an off the shelf product. Yes it's more junk to carry around. I guess the logical step is a light probe program for your mobile phone which probably has a camera built in anyway. The caretec probe will tell you the colour of the light on the gps unit and whether it is on or off or flashing. It's a worthwhile piece of junk to carry if you need to work with traffic or crossing lights too. Yes sure a gps with a mechanical switch would be handy but it's not an option as yet. -= Liam -----Original Message----- From: gps-talkusers-bounce@xxxxxxxxxxxxx [mailto:gps-talkusers-bounce@xxxxxxxxxxxxx] On Behalf Of Richard Myers Sent: 23 July 2005 02:13 To: gps-talkusers@xxxxxxxxxxxxx Subject: [gps-talkusers] Re: receivers Hello, Liam, A light probe is not a bad idea, but just more junk to carry around, and who is going to design it, and how are you going to use it if you do not know which light you are looking at? Some pretty tough questions. Better yet, what is wrong with an on-off switch or design a receiver that is on all the time it is plugged in, like the Earthmate? Granted, the Earthmate does have a light, but I think it just tells if the system is getting a signal or something like that, and your software will tell you that soon enough.

Caretec do one that is a colour identifier and light sensor or probe Use x cord to get an idea of where you are. Or hit F to find the nearest points of interest. - Liam -----Original Message----- From: gps-talkusers-bounce@xxxxxxxxxxxxx [mailto:gps-talkusers-bounce@xxxxxxxxxxxxx] On Behalf Of Wendy Miller Slominsky Sent: 22 July 2005 16:09 To: gps-talkusers@xxxxxxxxxxxxx Subject: [gps-talkusers] Re: receivers I just got the PK and for sure I love it and spoiled???? O yes, it's so easily carried around and so nice to not have wires hanging all over. The question is how people have learned to tell when the GPS is on or off? There is no sound and all I can think is checking if the PK has a signal. Also do you have to have it turned on all the time when it's charging? Second user question is how to turn on the unit and find out where you are if you're in an unformiliar place, do not know the town or county just the state. Is there a way to have GPS identify for you where you are?
