Hi everyone, 

Due to an unfortunate series of events, I need to get 25 x VHF transmitters (just the pingers - no collar) on a single frequency in around a 4 week turnaround time. 

I'm already chatting with Holohil, Perdix, and Wildlife Equipment, but does anyone know of any other good leads for this?

Thanks in advance, and all the best, 

Kas
