I think that speeding up play is the intent of allowing rangefinders to be used at the PGA Championship in May. Will it? I agree with Morikowa that it likely won't help. I'm fine with them allowing rangefinders as they already have the yardages readily available from their caddy within seconds. IMO, the reasons for slowplay are elsewhere.
