yea that is what i was kinda thinking about.. u could probably get them to sync but if one lost signal it would probably pick up the signal of which ever one had the stronger signal after that, you would probably have to turn them off and resync all of them... have u emailed the company about this question? i just bought one of those a AW131 2 weeks ago and havent had a chance to use it yet...are u pretty happy with it?
