Which radio transmitter for EOS 5D MK3 used with older Bowens GM500 (none radio) monoblocks

25 Aug 2019 8:52AM
Just bought some Bowens GM500 strobe heads that are non-radio, but have a sync socket on the back.

To be used with Canon EOS 5D MK3.

From what I can gather the GM500 heads have a cell built in so detect flash from other heads so I will need a radio transmitter to fit on hot shoe of Canon and a receiver to plug into the sync socket of just one of the heads to allow me to trigger them all.

Somebody said PocketWizard, but they seem pricy for a simple electronic device that simply sends out a quick signal. They might have features and functions I don't need, see my requirements above.

I don't want cheap crap that is built like crap that won't work, will break or be totally 'twitchy' and unreliable.

I know there are cheap brands out there: Godox, Neewer etc, no idea if these are any good though.

Can anybody recommend a budget make/model that I could buy. Also, for future, I'd also like recommendation for a higher quality make/model that I can upgrade to if the lesser one proves unreliable.

Godox are excellent but with those monolights you do not need the sophistication of the Godox system so something like this would work well Neewer

The cheap Chinese "Poverty Wizards" are all that I have used with my strobes. The same at the local camera club.

You only need one receiver if the second strobe can be fired optically by the first. They don't always work though especially if one of the batteries is starting to run low and you get the occasional non-fire. Sod's law ensures that happens on the best shot.

With the older design the like the ones linked to above theyy dangle loosely and if you forget to switch them off before packing up, the batteries will be flat when you next try to use them.

You can eliminate the majority of the batteries in the system by using ones designed like these same kind of system but neater and more reliable.
