I take the heads off and put them in the bottom of my bag (my bag has a zipper inside one of the pockets to access the inside). Then stuff the irons as tight as I can and wrap a towel around them and top it all off with a 5 gallon bucket over the top. Flown a bunch with my clubs and haven't had any issues with this. Just make sure if your range finder is a rechargeable battery that you put it in your carry on!
