This is probably a question I will have to call Marshall and get answered but I figured I would throw it out here first. I went to their website to order my new GPS system and UHF receiver and transmitters and I see where the RT-GPS transmitter comes with the GPS system but I don't see where I can order just the transmitter by itself. I want to backpack 2 birds with the same frequency transmitters so I can use the GPS system with either bird. At no time will both transmitters be on at the same time so there won't be a problem there. Is the GPS system made for only one transmitter and they want you to buy two entire systems?

Another thing I just noticed, when you click on BUY for the GPS System it has a drop down box at the bottom to upgrade the Desert Carry Case but it says to a medium. But back on the page it described the Carry Cases it says Mini and Full. Is there a medium or is that just a misprint?
