Focus pullers use equipment such as the Cine-Tape system, and Laser rangefinders, but the simplest method is a tape measure..

Also the really good 1sts can pretty accurately judge distance just by experience and watching the subject.

Use a Disto, the laser ones are more accurate, but more expensive.

 

If you are going to use it outside, make sure you get one with a bigger range as they are more powerful and work better in sunlight.

 

Ultra-sonic ones are far cheaper, have a lower distance range, however they work in all brightness conditions, so sunlight doesn't effect them.

 

If you need mm perfect, go laser, if you need to the nearest few inches, go with a ultra-sonic one.

Ultra-sonic is from any specific company? Any issues with Disto in lowlight conditions?

Mathew, I don't know these modern range finder devices at all,  but they all have to obey the functions of physics.  Any device that sends it's own electro magnetic fluctuation will be unaffected by the lighting level.  When one thinks about it,  this is just common sense.  So one could learn about these things oneself...have a go...google,  or books...then this may lead to better and more interesting questions.
