We’ve got “big” (8*42) bins from Celestron (Granite HD) and Vanguard( Endeavour, the original range). Both great, the celestron probably edge it and they do a 7*33 and 9*33 if you want something mid-size
for “small” bins we had some RSPB Rambler 8*25, they were ok – I tested them against the 8*20 HD binoculars and against some swaro 8*20 ish bins at at test event, and in truth I preferred the 8*25s. They were under £100 as opposed to 300 for the RSPB HD and over £500 for the swarovskis.
We lost them while out skiing (probably dropped out of the backpack) and have replaced them with – erm – something else. Frustratingly I can’t recall what hey are offhand. again though under £100.
If you want to pop round to try our bins James you’re more than welcome, drop use a line or give us a bell
what I have found is that I don’t find the smaller binoculars as comfortable to use as something bigger.
