Not surprisingly, the PGA has been hesitant to let golfers use distance trackers on the course. In theory, they take all the challenge out of picking the right club. The association isn't stuck in its ways, however. Officials have announced that they'll let players test distance measuring devices at certain tournaments on the Web.com Tour, the Mackenzie Tour in Canada and PGA Tour Latinoamérica. Competitors won't be allowed to gauge elevation, slope or wind, but this could still help them take more informed swings.
