To make it short: anything goes. Even quite well.
Purchase reason: wanted a pure logger, who accompanies me on walks, tours, photo tours. iPhone could do that, but the battery does quickly limp with most GPS apps. The Holux runs 24 hrs. Of continuous use and has good space for many waypoints, depending on the recording frequency.
Conjunction with the Mac: the link between Mac and Holux is the "USB to UART Bridge VCP CP210x Driver" (Google) company SILABS. I recommend explicitly the latest version (3.1) of the home page to load and install.
In the program settings is important to note that getting the right device is selected. In HoudahGeo is eg Holux, USB, SLAB_USB2UART. The latter describes the port and is often the source of all errors. If you have GPSBabel: Device: Holux M-241 (MTK based) Device Name: /dev/cu.SLAB_USB2UART
For software: the bundled software is available for Windows, Mac users need something else. Has been tested: HoudahGeo for Photo tagging - Go !, GPSBabel for Mac - Perfect. If you have created the GPX file with GPSBabel can also use GPSPhotoLinker, also freeware, Aperture comes with GPX files anyway. GPSBabel is in my opinion the best you can and do the Holux itself. Converts, modfiziert and can also transfer to erase the tracks and out of the device. Especially the filter function Tracks> Waypoint conversion is awesome, Route cleanup, Wegpunktelimit more. Large Class. It can also be created Google Earth KML files, even with directional arrows in the path. The tour in Google Earth again "depart" is great.
Currently, I can highly recommend "MyTracks" Dirk stickleback from the MacAppStore for 14. Grandiose import / export functions and editing tracks and individual waypoints.
I would like to warn against the BT747 program. Is often recommended, unfortunately, this program has the "power" the Holux to transform into a "Brick" (Brick) without function. "Holux bricked" is sometimes a Google search value. I do not even happened, because I initially relied on the recommendations. The restoration is a spasm and goes only by flashing the firmware. Short description for the poor devils who caught it might:
Load firmware from the website. It is absolutely a Windows computer required!
Connect the equipment.
Start firmware update. -> Autodetect -> Connect. No information on the Holux are displayed for this is the "Compel" button available. Compel click, select firmware bin file. Now it's funny. Side ON / OFF button and key arrow-right at the same time and hold to start a reset (the display will show nothing if the Holux "brick your" is). Now even while holding the keys down somehow try to click the "Execute" button in the Flash program. Until "one" count in thoughts and let go of the buttons on the unit. With any luck, the flash process is started. Otherwise, try again. It really goes like this. I could my Holux 245 so again "entbricken" after really nothing left.
For quality of Holux: Everything perfect. Rights. Be changed to German. All necessary information will be displayed and measurement intervals can be set. Actually everything you need. I am very pleased. Fasten takeaway, switched, Logger backpack with Carabiner. Done. Am very happy and have everything I need respect. GPS (Photo) Logging.
