Hi Nick,
I bought one of these,
http://cgi.ebay.com.au/ws/eBayISAPI....category=63 2
no connection, just happy with mine.

hmm. $Aud95!

Ok. I would still rather spend $300 and get a reasonable piece of gear
than $100 and get something that disappointsme.

Ok if I ask a few questions?

More to the point. Will you answer them? G

I have also just been out and fiddled about with my Class II pointer
G and may have some ideas.

(1) If you can make a shade for the staff, with both top and side
shields, you can significantly increase the visibility. You would need
to turn the staff so that the side shileds kept the sun off. There are
a couple of spots where this would not work, of course.

(2) 3M make reflective film. I have some red stuff. That really makes
the lazer point stand out. May even be a safety issue for a static
lazer.

I can see it maybe 25 meters in sunlight using the red tinted glasses that
come with it. I just turn it on and walk about with a staff I made from a
tomato stake witn the blade out of a $2.50 tape measure nailed to it, it
works very well.

I hate ebay....however, it certainly seems to be reasonable and if
it's OK up to 25m that's not bad!

So you are close to the staff, and can see the laser stripe on it, I
guess. I can see where that would work. I have a laser pointer, and in
sunlight I can't see the point if I am _at the laser_ and the beam is
more than 10 metres away. At night, I can see it against a wall 250 m
away!

I was assuming I was going to need to point, locate and mark. Of
course with a rotating bizzo, you can walk around and see the beam.

What rotation speed do you use? I am interested because I would assume
that the faster it turns, the quicker it wears.

Does it take rechargeables? What capacity and whow long does a set
last?

How do you set the thing level? Bubble? Auto?

Have you done an "back checking" on its levels to see how accurate it
is? By this I mean actually marking a level that it gives, then
marking its own level, placing it at the new level and seeing it sends
back to itself.

How big is the spot?

Just to prove the point Rob made about damn engineers, I don't trust water
levels because they level to a curve about the the same as the radius of the
earth, where a laser is flat. LOL

......with a "thin spot" in the middle of the "run"? G
