I purchased the a Sekonic L-758DR light meter, Pocket Wizard Flex TT5 and a Mini TT1 for Nikon iTTL flash systems, I'm using them with a Nikon SB-910 Speedlight off camera. I attempted to set it all up, that's where the problems started!

I cannot make the proper connection to fire the flash using the FlexTT5.However, using a Nikon SU-800 Commander I can fire my SB 700 Nikon flash and a Nikon DSLR camera, so I must be doing something right.I did go into the Flex software, maybe that's where I went astray.

This replaces an old one that failed due to old cruddy batteries.Combined with the sender unit, this system sets up easy and works from all angles.

Work perfect in the distance. Is my number 5 PocketWizard that said everything.-

very easy to use, but after 50 jobs 2 out of 3 broke,

Works just as I hoped it would

Inside my house (where they worked): Finally got the TT5s NOT to fire the SB-700 flash by placing them on different floors AND different ends of the house. Impressive compared to the Nikon SU-800.

Simple to use and communicates well with my cameras and speed lights and it's firmware is updatable to work with new gear .... beta at this point on the Nikon D500.

I own half a dozen of these slaves, which I use with Nikon flagship flashes. I use the MiniTT1 slaves on the cameras. They have worked great for me, allowing me to light large areas with 5-6 strobes.

I use my pocket wizard gear at every wedding throughout the year. I have been using the FlexTT5 for the past three to four years and it has served me well. I use them with my mini TT1 along with the AC3 Zone Controller. I have two sets of TT1 and AC3's that are on two Nikon cameras.
