I'm very happy with Labradar. Very good product, but not 5 stars because of certain problems.
First of all, thanks to Mr. Brandon Davey for his quick response and help.
Labradar delivers what promises. My goal was the tracking file (.CSV) of each shot (time-distance-speed) at 1 ms intervals.
Two minor drawbacks:
1.- I couldn't get the android app to work. I've tried to no avail with three different devices running different android versions. I hope a new firmware/app versions will solve the problem.
2.- Without a card, Labradar does not allow to download data to the computer.
3.- The card reader is a little bit picky with the card. The manual does not specify card's maximum size nor recommend any particular card. Many people complain about it. None of my cards worked. I've bought 4 cards in a row and fortunately all 4 work fine and are not expensive. See pictures and links:
Sandisk ULTRA SDHC UHS-I 32 GB
Sandisk ULTRA SDHC UHS-I 16 GB
Sandisk Extreme SDHC UHS-I 16 GB
Verbatim Premium microSDHC -I 16 GB
I would strongly recommend it.
