Flashing Green Light On Blink Sync Module

Very good device but hardly fast speed and external light keep flashing green. But over all everything seem fine

I'm using this to sync a Ninja V with Sync module to my F6. I wasn't completely sure that would work but it works great, and just lives in the F6 all the time, plug it in and forget it.

but it is unsettling to have the upstream light flashing

I too just purchased for trusty GoPro Hero 4 to use with Ninja V and the AtomX Sync module. Works like a champ! Not only perfect timecode sync, but wireless record start of the GoPro to boot, measured at 5 frames after the Ninja V starts. The concept that I can start the Ninja and the gopro by one press of my Z6 release button, and align them to timecode blows my mind. Very convenient, and the RF channel communication is more solid than dealing with Bluetooth. Set and forget so far.

5 stars! Stable and very easy to adjust level with slider on.

Works well and doesn't take up a ton of desk space. The front blue light does blink while ots actively transferring and can get annoying so I just covered it with gaff tape.

I've owned several d2's in the past -- all quality purchases. My early view of my new 14TB d2 Pro's is they are large capacity; solid and fast performers; exceptionally quiet; warmer to the touch after extended read/write sessions -- but not of concern; and without any other setting or intervention they automatically sleep and wakeup soon after my Mac does. In my opinion, you get what you pay for and these are worth every penny. The only downside is the blue status light is B-R-I-G-H-T enough to light a dark room at night and can be distracting if they are blinking while you're trying to sleep even down the hall, or if you have them running perhaps in an office when people outside will think the Martians have invaded the place with the bright blue blink-blink-blink. I placed a piece of dimming film over the light and I still have a visual status what's going on with the drive, but without the nighttime glare.

This is a very nice headlamp, without two levels of white light, a red light and a flashing red light.  Having the battery pack on the back makes it much easier to balance and the straps are adjustable over a wide range.

Great size, love the built in light (it has flashing mode for some reason, just if you need to give someone a seizure on a film set?) I have always wanted this Porta Brace bag but kept talking myself out of it. I finally pulled the trigger on buying one and I'm glad I did. Sometimes I have a small lens in it if i am shooting an event with a smaller camera, but on a full set I kit it out with all the tools I'll need. for camera department. If you are on the fence about it, do it.

This flashing is amazing. The variable light settings to the strobe. No concerns on purchasing the light at all. I would love to give one to every person in my family. BUY IT YOU'LL LOVE IT!!!!
