Data Collectors with 2 Bluetooth Modules

Fellow surveyors, I'm trying to figure out what data collector options there are on the market that come with 2 bluetooth modules built-in, or at least the capability of connecting to, and collecting data from two separate instruments at the same time. In?ÿ my scenario that would be an echosounder and a GPS receiver.

I understand that Timble/Spectra TSC3, Topcon FC-500 and Hemisphere XF3 are some options, but are there others? And how can you tell? None of the spec sheets for those give any indication that they are capable of doing it.

Any help would be appreciated.
