Bodyfat% montoring?

[TheRipper]

I was wondering if anyone uses these while cycling just to see if they are gaining fat or actual muscle mass.I went to a clinic years ago and used something like it and seemed like it matched up to there more expensive machines pretty well.I live out in the sticks and it would be atleast a 60 mile drive one way to get my bf checked.My gym does not have anything for testing not even calipers.

I forget which way the BF changes when you are well hydrated versus not well hydrated. Correct me if I am wrong here but the more hydrated you are the less your BF and the less hydrated you are the higher your BF correct?
