Free wrote:mono or binocular. Do you want it for school or medical diagnosis?
Its just for an 11 year old who is keen on science - not looking for anything too expensive though - just a basic thing to look at all sorts of samples (hair, skin, blood, vegetation, dirty water, insects, etc etc) - and start getting an idea about cells and micro-organisms, etc
If its binocular I think that would be better than peering with one eye.
If I can also have some ball park figures to aim for...
Thanks!
