Using laser distance meters in bright sun

unearthed

I've been reading this post with interest as I have a Disto and have been looking for a way to add horizontal measurement, but most systems are very buggy and/or very expensive, but some Swiss cavers have added a third-axis upgrade to a Disto A3 http://paperless.bheeb.ch/. Apparently it will work on other lasers, but the Disto has greater accuracy and functionailty (and the Disto A3 has enough room within the case for the upgrade). The device uses the Disto's memory to hold the resulting point cloud prior to Bluetooth transmission to PDA for field-drawing or for building into a drawing later.

I'm considering getting someone to build me one of these, as it's essentially a poor-man's electronic theodolite, and would revolutionise field work. I understand they cost around 150 Euros to build (and the site has full specifications and construction info for the electronically-minded)

Just thought you might be interested in this.
