If you want to see a unit in the flesh, see how big & heavy it is, fine, but to get a real idea of how the kit you're looking at performs in its intended environment then yep, waste of time! A bit like trying out binos in bright sunshine looking at objects that are already visible to the naked eye then finding that at dusk you can’t tell the difference between a clump of bramble & a roe deer!
@DeadEyeSimo. - I’ve had a Lynx LH25 2.0 for about 18 months now & have been amazed at how much you can see, both in terms of seeing deer at distance, being able to differentiate between roe & fallow at up to 500 yards clear line of sight & easily tell the difference between a doe & a pricket at usual shooting distances. Albeit that you do need to know what you are looking at in the first place, ie recognise the form & gait of the species as well as the tell tales between sexes.
Stalking buddy bought the LH35 2.0 & he wishes he'd bought the 25 as field of view is reduced & base mag is higher which hampers things close in, eg looking for a fallen animal in cover in the dark.
