I have the same chrono w/ an indoor IR lighting kit, and love it!
I did run into a few gremlins though, and I'm not sure if others will too..
IF you get the chance, and want to see what happens if you do the same thing:
I installed the Digital Link app on 2 devices. 1 on my phone and 1 on my PC.
I connected the chrono to the phone, and shot a string..
When done, I saved that data, and sent it to myself via e-mail.
Now, in the Phone App settings, I configured everything to US measurements..
Ex: Feet Per Second / Foot Pounds of energy.
Then I ran the PC app, and imported the file..
When it opened in the PC app, all of the info had been changed/converted..
It read in Meters/second and Joules..
I have no clue how or why, there was no way to correct it,
no one seemed to have an answer to it, or had done the same thing to confirrm..
I have a 'help thread' buried/lost somewhere on here, but still no 'fix'..
