I've stopped using these pretty blue targets that came with the scanner as too often the laser reflects upwards off the little squares and creates a black streak upwards about 3 or 4 times the size of the target.
This in effect creates an area with no point data.
Very few times have I managed to get these targets to work as they should.

Any tips?

I try to play between working for Leica and being a moderator for this forum. The coments below are with my Leica hat off.

The targets above which were disigned years ago by Babcock/signplus. this was back in the HDS2400/HDS2500 days.

I have used these for years and they are very good particually the ridged ones with the double sided sticky, as they can stick to slightly rough surfaces while staying flat. The black sighting marks don't seem to make any differance to the target aquisition and helps when sighting with a Total station.

The manufacture of the targets differ slightly from the Leica ones as the small silver dot is stuck on to the front rather than being embeded, I have never done the tests but there could be a slight differance in the accuracy.

I would recomend them to all. There is also a bulk purchase option.

Ok hat back on.

If you are working at the top end of accuracy I would keep some of the offical ones around as at least Leica will guaranty them to work.

I always keep a few of the Leica magnetic ones to hand on site which are great when you need a quick target.

Apart from our collection of Leica Hard targets, we use a paper target which incorporates the black and white target that comes on the Cyclone disk. (Actually its a grey and white target don't know why they call it B&W). We have added some contact info, space for ID and other verbage. We buy 8.5 x 11 peel-off laser labels for $120US for 1000 and print them on the laser printer. Have never had a problem with the HD 6000 picking them up.

These are not designed for the HDS6100/6000, hence why they don't work.

Use paper copies of the one located at c:/program files/leica geosystems/cyclone as rlasater discusses above.
