Just been testing the Pixel Soldier TF-373 flash triggers I brought on eBay, they are AWESOME.

In house test next to my wireless broadband router etc. they never missed a beat on full power single shot or rapid fire 1/16th power camera in Jpeg mode to keep going without buffer 30 plus shots.

Outside line of sight I ran out of road in my close 300 yards single shot no miss fires and 300 yards rapid shot 1/16th power jpeg mode 20 shot before 1 miss fire.
They make my old Ishoot triggers look like Noah’s ark material. Well pleased.
They also do these for other camera makes.
Happy snapping Aidy
