Holux M-1000C Bluetooth GPS Data Logger Travel Recorder (Bluetooth, USB , 66CH, WAAS, 200k Waypoints, M1000c) Review

Average Reviews:

(More customer reviews)I own a standalone Globalsat BT-338 receiver, have a built-in GPS receiver in my HTC Touch 3G mobile, and have a GPS enabled Garmin Forerunner 405 watch/running computer as well. I needed one receiver with long battery life and data logging capability on an affordable price, so I went for the Holux M-1000C. Comparing the reception and the stability of the receivers the built-in Sirf III receiver of HTC has mediocre, the Forerunner has good and the standalone Globalsat and Holux both have excellent sensibility.
The Holux gets fix quite quickly, usually in 30 seconds. It always helps if you don't move while it searches for the satellites, and once it gets fix it never loses again. In urban canyons, such as among the downtown high-rises the signal tends to bounce a bit in every direction, thus later I always modify the tracks with the so called 'clamp to the ground' function. It modifies the height vector based on Google Earth data and eliminates the vertical bouncing and produce a much more realistic elevation diagram - very similar to the barometric altitude meter results. Unfortunately the bound ezTour software doesn't offer this function, but for example the (ex-Motionbased) Garmin Connect web service or the free TCX Converter utility do it for you.
The logger function of the M-1000C is excellent. There are 4 preset modes for logging: car, bike, running, hiking. In hiking mode for example records a waypoint in every 3 seconds and in every 10 metres, while these values in bike mode are 5 seconds and 5 meters. But it is possible to set these values manually according your preferences as well. The memory is huge, 4 hours of running log (recording in every 5 seconds) occupies 1% of the memory only.
Handling is easy: you turn it on, wait for the GPS led blinking (meaning fix) and there you go. When you finished just switch it off. Later in ezTour you can see you track in Google Maps and it is possible to modify your tracklog, like delete unnecessary waypoints, moving waypoints etc too. Unfortunately you cannot see the map under your track while you in Track Editor mode, though editing your track is reasonable manageable. While ezTour will not be your primary GPS track managing utility it does the basic stuff.
The Holux M-1000C delivers why I bought it: it can record the track of a week long hiking (with some external charging solution or spare battery as the battery last 'only' 28 hrs in logger mode), and I can use it as a bluetooth GPS with my navigation software on my HTC mobile if the built in GPS receiver gives up and/or I want to record my track.
Oh, did I mention that you can geotag your pictures with it?

Qstarz BT-Q1000eX Professional BT Data Logger GPS (Lap Timing Analysis, Beeper, Vibration Sensor, 5Hz, 400,000 waypoints) Review

Average Reviews:

(More customer reviews)This GPS data logger works great for the price as a motorcycle lap timer with the added bonus of GPS location info allowing analysis of any part of the track such as corner speed and location at 0.2 second intervals. However, it would be nice if it logged at 10Hz versus 5Hz. With GPS accuracy of 6-9 feet I don't know if it would really give you much better information as far as track location on the width of the track but would give you more information on speed through the corners as even at 60 mph you are traveling 88 feet per second and so at 5Hz you are only getting points every 17.6 feet. 10 Hz would bring the data points inline with the accuracy of current GPS systems with a recorded point approx. every 8.8 feet when traveling at 60 mph. You must download the data to a computer and use the companies Qsports software with lap analysis function enabled to view data since no local LCD screen controls etc..., but if Qstarz added these would definitely raise the costs which at the current price is a great deal and why I decided to purchase. A couple recommendations I have for using the gps data logger as a lap timer are to not select the check box to remove drift points when importing data from the device, I have not been able to determine from the literature what removing drift points actually does, but has messed up some data. The other recommendation I have is to download/import data from the device to the computer after each session on the track and delete the data stored on the device after successful import. The time for import is not as long and it ensures your sessions are kept as separate data files.

BT-Q1000eX is an extraordinary GPS Lap Timer with eXtreme 5Hz log speed which enables Q1000eX to log up to 5 times per second providing most accurate measurement of track, speed, and distance. Such characteristic makes Q1000eX very suitable for every kind of extreme sports activity, especially for super moto, road course motorcycles, oval cars, or road course autos. And drivers can also improve their lap time by valuable driving information.Q1000eX GPS lap timer is simple and easy to use. It's stand-alone without the help of other accessories like transmitter are unnecessary. It adopts the GPS technology to log your race and later you can upload your driving information via USB or Bluetooth to PC for the included Lap Timing Analysis software to analyze the data. After manually define the start, finish, and split point on Google Map, you can see the very detailed driving information as following: Avg/Min/Max speed by each lap, Sector time (the time from one split point to another), Split time (the cumulative time from start point to split point), and point current speed.Other than as a GPS Lap timer, BT-Q1000eX is also a very powerful data logger with 8MB memory size able to log up to 40,000 waypoints and long battery life to continuously operate 42 hrs, which give a very strong base to support the huge demand by 5Hz log. It also integrates A-GPS, beeper, vibration sensor. A-GPS can boost the GPS warm start time to less than 15sec, Beeper can notice the device status, and Vibration sensor can smartly save power and recordable waypoints. The included dual software: QTravel and QSports even strengthen the applications of Q1000eX on many aspects, making it become a multi-functional device no matter for lap timer, for navigation, for travel log, or for sports log.
