I think that this topic was discussed several times. But I did not find it(
So what is the best choice of commercial external GPS recievers?
Let's say that upper limmit on price is 150 dollars.

I found that in this forum people discusse Qstarz BT-Q818 Bluetooth GPS Receiver.
Is this best item?

    That's the unit I use and I find it's great. Quick fix to satellites and it looks like good, reliable data.

    There's many versions of the Q818. Make sure you pick the one that actually is 5Hz like the BT-Q818X. It should be under $90.

    thanks!

    I bought a GlobalTop G66 Touch Bluetooth GPS on ebay, it cost $35.50US including fregith to Australia. It is a 5Hz unit.

    It worked perfectly. I am using it on a bike for lap timing and it is small enough to velcro on the inside of the fairing. It never missed a beat.

    I am using it with a HTC TOUCH HD.
    I tried the internal GPS which did not work at high speeds.

    Very impressed and Ialso cant beleive how good RaceChrono is, now i have it working.
    I hope this helps.

    Thanks for the tip yoshiboldor! Ordered myself a Globaltop on Ebay today.

    Couldn't find anything cheaper than 42 euro (~$51) but I managed to haggle a bit and got it for 35 euro (shipping included).

    Should it perform under par it's not exactly a disaster for the money.

    What's the difference between the BT-Q818X and the BT-Q818 extreme? Which one works best with Racechrono and a Nokia 5800?
  • AdamwAdamw
    Teimurlang,
    BT-Q818X is the newer MTKII chipset, longer batery life, faster fix etc. BT-Q818 is older MTK chipset. Either will work ok but Q818X is the better one.

    I believe the 818x has a hardware switch to keep it on 5hz and the 818 requires a software program to set it to 5hz and if it ever runs out of battery completely, it will default back to 1hz..yuk,

    Adamw and tentenths, thanx for your answers!!!

    Does anybody know what will happend if I turn all output NMEA settings to 5.
    I mean these: GLL, GSA, ZDA, RMC, GSV, MCHN, VTG, GGA.

    As I understood numbers mean frequency in Herz.
    Why not to put 5 everywhere?
