Once you start using of camera flash, pretty soon you get to a point where you'll need a way to trigger your flash. And when a cord just won't do it, you'll want a wireless trigger. After doing some digging around I figured Pocket Wizard Plus is probably the best one can buy. But that again, spending over 700NIS for a single Rx/Tx unit was not really an option. Considering the fact you need at least 2 to do anything, it's a lot of money. Luckily, there is a decent option for much less.
