I have an old but very serviceable W-1000-15 for sale. Ideal spotting unit, robust (bombproof) and easy to use.
It runs on 6xPP3's in a removeable battery pack and comes in a field bag with the video out connector. It's around 2x mag, has a good detector and can spot easily out at the distances of the equivalent models from FLIR, Guide, Pulsar etc.
When tipped vertical, there is some noise from the spindle bearings on which the detection disc sits - this can be quite common as it is done by overextending the focus reach (which can press on the detection sensor) - and most importantly it doesn't affect performance. I do however recognise that this affects the price.
There are lots of videos etc of it being used on tinternet and full specs there too.
More than happy to field questions as needed. £1000 is I think a steal of price for this please.
