A putter with a distance measurement mechanism comprises a shaft, a head
disposed on an end of the shaft, and a grip disposed on an opposite end
of the shaft, wherein the grip comprises a through-hole is formed on an
end of the grip, and an indication member having a scale extending from
the through-hole toward the shaft. The scale may comprise marks
indicating at least one of a distance to a cup and a recommended
backswing amount. The player looks at a cup on a green as the player
holds the putter, positioning an end of the grip at eye's level, the
player reads off the scale of the grip to estimate the distance to the
cup and the recommended backswing amount.
