Does any one know where I can have under water weighing done

I am looking for a place any where in Maine that does under water weighing . Please let me know if you know of any place in the State. Thanks

 I thought EMMC did it, though they didn't for me.  With modern technology, there are other ways that are just about as good.  I know the EMMC Diabetes center has a nice modern scale that does bone mass/density, percentage of body fat, etc...(heck, you can buy those at Bed Bath & Beyond now for under $40).
