User Reviews about M-241: Holux M-241 Bluetooth Data Logger GPS (Runs on AA Battery - MTK Chipset - 130 - 000 Waypoints)
Not a bad little data logger and even better with the new firmware (adds a feature or two to the GPS). If I had to knock this, it's the software and the battery door. The battery door appears flimsy and a bit of care is needed when replacing batteries so you don't break it, once in place, I think it's fine. The software is laggy at best, a lot of features, but just not quiet there. I use the software to load the waypoints, then save the data into KMZ format so I can use it on Google Earth which works much smoother. The stock software lets you convert to KMZ, so no need to hunt down something to do it. Would have been nice to have a larger LCD to see things like Speed from a distance and a better antenna or the ability to add one, but all in all, I like the logger pretty much the way it is and only have the heart to ding it one star, which really, I shouldn't do that since I got a great deal on a nice little GPS. Oh, and the blue-tooth does work, but have yet to figure out how to turn the BT off (new firmware suppose to let you). Battery life is about 16-20 hours of continuous use on one AA battery, not too bad, but make sure you have spare batteries with you, better with Name brand and not rechargeables (Somewhere I read about the battery meter misreading and will shut unit off with rechargeable, haven't tried it to find out). Good luck everyone and have fun with your GPS's, I know we do! -- Holux M-241 Nice little logger
Product worked perfectly under very adverse conditions well north of Winnipeg, MB. Acquired satellites quickly and battery life worked out well. 6 Lithium AA's lasted for 10 days of canoeing. Unit operated well inside a small waterproof camera pouch even when the operator managed to dump the entire contents of the canoe in a very cold lake. Software works well for my needs and allowed some editing of photo tag and track. Took a day or two to get used to but I liked it. -- Canadian North Woods
Cute little gadget. It is a comparatively fast and sensitive little Bluetooth GPS unit with a tiny display that can show Lat/Lon/Alt/Speed/Compass/etc. and has a backlight. It will also automatically or manually log waypoints and routes with a modest number of configurable options. It works great with my Treo 680 Smartphone and DeLorme Street Atlas USA 2006 Handheld Edition. In fact it is more reliable than my DeLorme Bluetooth GPS's. Running 12 hours on an alkaline AA battery is rather amazing. The fact that the accompanying software can export the saved waypoint and route data in a number of formats, including NMEA and Google Earth KMZ format is cool. The software is a bit primative but it seems to work. I hope they come out with some updates.
Now for the negatives.
The USB driver doesn't seem to work properly on XP!!!
It seems to work okay on Win2K Pro.
Fortunately it is possible to connect your XP PC and the data download software to the M-241 over Bluetooth and get the data off of it. Slowly.
And Holux Technical Support (email to China) seems to be strictly a one-way communication medium. You send them emails and nothing ever comes back.
Would I buy it again? Yes! It's cheap and works great as an amazingly sensitive and fast little GPS. And if you can negotiate the usual quirks and user hostility of Bluetooth, you can make it do everything that Holux promises it can do. However it sure would be nice if Holux fixed the stupid USB driver for XP!
