a way to communicate between snowmobiles

OK, so what is your question

there are plenty of motorcycle intercom/two-way radios that would work for snowmobiles. i'm sure you could find some cheap ones on ebay.

They are available everywhere.

And this question has nothing to do with curling.

There is a couple of companies that make them. l prefer the ones made by Collett. they are made well, have good reception and clarity while you ride. they also have a auxillary jack to plug a MP3 player or radio into so you can listen to music while you ride. if someone talks, it cuts out the music and puts their voice thru. then when they're done talking, it puts your music back on.
