Graham,
We have been using the Leica Disto laser tools for a while now. I have the
A3 which is pretty basic. It is difficult to see the laser over a longer
distance or in bright light but is very accurate when measuring crown
spread. My colleague has the A5 which has an integrated viewfinder which is
better at further distances.
However, we have just purchased the trupulse 200 laser tool. It is fantastic
and really simple to use. You look through the monocular lens at the target
and point and shoot. It measures horizontal distance (built in automatic
level), slope distance, vertical distance and best of all really accurate
height from any distance. It was recommended by a friend who does line
survey work.
Checkout the video demo at:

It has proved to have been valuable especially when working on sites with
poor topo surveys. It is tripod mountable and has a port to download
readings directly to a PDA or for a bit extra cash there is the Bluetooth
version.
Ours is the basic model and was about £600+vat

Morning all
Does anyone have any advice over what to look for when buying one of these?
Can they measure dbh and crown spread to sufficient accuracy for 5837 for
instance?
Thanks
