Is there any way to remotely trigger my Promaster 7500DX, besides slave???

I dont want to use any other flash to trigger it because i only want one flash to pop.

This flash unit does not have any sync cord input. the only way to connect anything to this thing is via the hot-shoe.

I looked at pocket wizzards but it looks like you have to connect them with a sync cord.

Are there any remote triggering devices that have a hot shoe for the flash to fit into?

I hope i explained this well enough.

Thanks for the help!
