Qstarz BT-Q818XT 10Hz 66 Channel Bluetooth GPS Receiver

Ive had this a few months now so good time to review.It's small and compact. I use it for GPS on my phone for navigation and geocaching. It's much better than my Garmin GPS unit under tree cover. It finds satellites very quickly too.It connects effortlessly to my Samsung Galaxy phone.The 10Hz feature has it's place as a motorcycle data logger on track days coupled with apps on the phone and it works perfect. The phone logs the data and it works under the bike seat!!.The housing is reasonable quality, the selector switch on the side is a bit cheap and not that positive in use. It has a rubberised underside which is handy when on the car dash, etc. Battery seesm to go on for ages, I havent run it down yet so can't say how long it lasts, it charges quickly too.Overall, it's a great little gadget and very useful. I would recommend and would buy again.

Good little gadget, good battery life and gets reception ok, although I havent tried it anywhere difficult yet.I got very confused to start with as the bluettooth light wouldnt come on in the 5hz mode...and for ages it wouldnt pair, then i tried in the other mode and it would pair...and then worked in the original mode!

For the first two weeks I loved this product. I used it in the motorhome in conjunction with Co Pilot on my mobile. It quickly got a signal from the satellites and the battery life was excellent. Sadly thereafter it wouldn't pair with the Bluetooth GPS app on my phone. I contacted the manufacturers and they confirmed the unit was faulty. I got in touch with Amazon, who immediately sent out a replacement. This one works fine, but it has left me nervous that it will let me down again. Wouldn't be good if we were on the continent.

The GPS is better accuracy than my LG G5 smartphone's built in. There are a number of configuration settings if you feel you want to adjust them but information about what they do requires research. And the software takes a bit of finding and setting up. I bought it because my LG G5 GPS needed resetting frequently (a design fault). With this Qstarz BT I could choose to buy any phone now, if I need to upgrade. The accuracy is very good (usually 12 feet, have seen 10 feet) - under trees it's about 18 feet. The old GPS satellite system seems fine in UK (it's now an older GPS chip). Took awhile to work out how to set up OruxMaps to get a accurate tracklog - OruxMaps has a ton of settings!

I bought this after a friend recommended it (I was impressed and it seemed to work really well with his android phone)A quick search of the internet tells me that this is incompatible with iPhones (and other iOS devices). I found out the hard way and had to do a return. This could be made much clearer in the text above.

I bought this Bluetooth GPS Receiver for use with RaceChrono on Nokia E61.First I configured Q818XT mode switch for 5Hz DGPS witch is said to be the best mode for lap timing.I have used duct tape to tape the GPS in the cabin near the motorcycle dashboard and then E61 in the pocket of my leathers.So far five track days and zero problems. Very good reception and quick fix on satellites.Very good product!

I can't understand comments from geo-taggers. What is the purpose to use 10 measurements per second for this purpose?This is pure motorsport device to use with RaceChrono, TrackAddict etc. and it does exactly what manufacturer describes.I purchased this version of device (not newer one BT-Q1000eX) because new version is the same 10Hz just with internal memory I do not plan to use (my data processor and storage is Android device) and software I do not plan to use too. From price perspective this version perfectly fits my requirements and is 2.5 times less expensive.

Works good, when works. But stopped working. Maybe it was to much in the sun (racing car, by the windshield during hot day).

Acquista per metterlo in combinazione con l'app racechrono pro, settato a 10Hz e con buone condizioni meteo la fedeltà al tracciato è quasi perfetta i tempi differiscono rispetto al trasponder della pista in media di 1 decimo, lo consiglio se volete trovare un compromesso economico ai più costosi laptimer.

avoir un module GPS de meilleur qualité, plus fiable et plus rapide que le GPS des Téléphone …. ce module réponds tout à fait à la tache qui lui est demandé !! entièrement satisfait du produit !

Antena GPS por bluetooth, tiene dos modos de emisión, 1mhz y 10mhz, son las veces que emite por segundo, va fenomenal para utilizar junto a la aplicación RaceChrono, y tomar tus tiempos en circuitos, tanto de coche como de moto. Juntos forman un laptimer de primera calidad con muchísima información útil. Además coge los satélites muy rápido.

Fast delivery, works well!
