Unless your proportions are much different from mine, and unless you swing your
coil way out in front of you (instead of about 1 to 1.5 feet in front of your toes), I expect
the Racer to fit you OK without any modifications.
I'm even happy with how the hand grip fits me, and I almost always have trouble
getting things to fit my large hands properly. (My fingers aren't especially long, but
my palms seem to be wider than expected, even for my size.)
Good luck if you go ahead and get the Racer! I'm enjoying mine.
By the way, I named myself TallTom on the forums because I started on them by asking
the same question you did, but for my first detector, a Tesoro Silver uMax. I wanted to
find out if it would fit me, and tried to make it clear that most things don't fit people
my size very well. In my family, we regard the phrase "One size fits all" to be a
tasteless joke. So I definitely sympathize with your "Will it fit?" problem.
