(+) Precision GPS data
(+) Receiving quite sensitive and partly indoors / window close possible
(+) Compass data (only for transmission via hot shoe) are transmitted and can be displayed in the camera screen
(+) Clean connection / seal on the hot shoe. If this is not locked, no connection takes place.
(+) Option, only use only as a data logger (without a compass). With subsequent processing can add (using the supplied software) GPS-data in the EXIF data of all photos / camera models.
(O) the current price policy / Trend following. Conveniently is different.
(O) for Canon can not: the compass data can only be with the Canon Map Utility (and this only with an entourage of other software) represent. Lightroom 4.4 nil. As far as I know, at LR5 also. But is sure to come.
(-) Entity receiving. Initialization even at best outdoor conditions always after minutes. Also, if the module was previously at the same location on directly. As someone said, not suitable for the quick shot.
(-) Compass data will be strongly influenced by other devices / wireless networks
(-) Battery indicator only 2 steps LED blinking: good or bad. A more detailed display in the camera's menu would be desirable. So you do not know how long the battery will last yet
(-) Very sensitive matte casing. Even after two days of use totally scratched / shiny patches. Once easily with your fingernail on the housing = stroke. Would have been possible for the price no magnesium alloy?
(-) 38 hours operating time with one AA battery is very little
(-) Bright, red, blinking status LEDs (battery, GPS receiver) can not be dimmed / off. In some situations, but that would be desirable. There is still taping.
(-) On / Off switch not locked
Conclusion: Despite the negative points you can not get unfortunately this product around if the GPS data to be inserted in the recording, and one a "lean" system wants. Perhaps the negative points are still partially solved.
In my view, therefore, just three points ...
