Thanks everyone for the suggestions. I downloaded AlignMaster and look forward to testing that out in the next few nights (it just clouded over here!). I also found PEMPro which is similar in purpose but more complex... not necessarily more precise, but it has a few other extra features that may be handy. I'll test them both out and let you know which I think is better (although PEMPro is substantially higher in cost!).
Thankfully, both have trial periods.
Richard - that idea of having a pre-marked position on pavers is certainly something I intend to do... especially given that initial precision you claim!
Regarding the alt. moving by 4degrees... the tripod itself was most definitely perfectly level when I started. I checked it with a spirit level. Is that what you meant was out of level? Or is there something else that I haven't leveled? (I was suspecting it was an issue with the HC firmware, erroneously reporting error margins!)
Thanks again to all.
