Paul & All,

I've had a few disasters with binoculars and I've lost count of the actual number I've used up, but let's start about half way through the saga, they are all roof-prism type:

Pair 1, (cheap) dropped into water, ruined.
Pair 2 (cheap) I almost lost over a cliff edge at Katherine Gorge.  They hit rock and lost alignment but I mended them myself using dental floss to rebind the prism inside.  The prisms appeared to be held in place by what looked like blobs of sealing wax, not built for hard knocks.
Pair 3 (cheap) went out of alignment, probably dropped them.  Took them to an optician somewhere outback and they handed them back to me in even worse alignment.  (OPSM not recommended for collimation.)
Pair 4 (cheap) I left sitting on the bonnet of my car near Lake Eyre, drove off, didn't notice until 400 km further on, lost binocs.
Pair 5 (cheap) eventually fell apart and did not have good alignment to start with, gave me headaches.
Pair 6 (expensive! Swarovski! lovely!) haven't dropped or lost these during first 4 years of ownership - the price tag helps.  Also I think the construction of the Swarovskis is very rugged and knock-proof.  Mine are 8x20 and a perfect size for watching birds while I'm recording them.

A few weeks ago I dropped my binoculars on soft ground (again). This threw them out of alignment. The company that used to collimate binoculars in Newcastle is no longer prepared to do it and suggests I send them to a firm in Sydney who charge $80. This morning I accidently dropped my spare pair and now they need collimating as well. I can no longer afford to keep getting my binoculars collimated and the inconvenience of sending them or taking them to Sydney is too great. Seems to me I have four options:
1) Fix them myself
2) Find someone in the Newcastle area who will do them at a reasonable price.
3) Buy a new pair that are rugged enough to survive the odd bump or two
4) Give up birding
I would be interested to hear if any birding-aussers could help with advice on any of the first three options (option 4 I would have to manage on my own, although counselling might help).
