pllllllz help me
can i used the xbee pro s2b (((((( underwater )))))))
**& i neeed the freq rang **
No.
Please tell us more of your project.
Words of miniature submarine inside the device, and I can identify the places (GPS) , I can I move them and move them from place to place remote

If you can make a radio work underwater, the navy very much wants to hear from you.
@ragheed
I do not understand what you try to accomplish. I can guess but that is wasting time.
Please use google translate to write a longer story (100+ words) in English as I see it is not your native language.
It will be easier for you to type it in your native language (which is not English I guess)
And yes forget about XBEE under water (see above posts)

No they don't, they already have means to communicate to their nuke subs while underwater using RF. How else could they give the release the beast command?

Yes, but it involves LF, VLF, or ELF frequencies and veerrrrryyyyyyy long antennas trailed behind the sub. And they aren't very deep when they're receiving.
GPS doesn't work under water either.
So you'd need to surface to get a GPS fix.
Do a search on DIYdrones submarine to find out the best way of doing what you want.
Buy an APM 2.6 or an APM 2.5 clone, they are an Arduino compatible board, with compass, gyros and accelerometers etc, plus you can attach an external GPS and external compass if needed.
You'd also probably need some other external sensors e.g some sort of water speed detector, some sort of depth gauge,as the APM barometer won't be much use, and probably some sort of sonar system.
