I like Hawke scopes my self , I have tried a few other makes like Niko sterling which are ok but not as good as Hawke , mtc which I have tried a few different models but just find reticules are all to fussy and mamba did suffer from white out in low light a long with fussy lines everywhere.
Discovery which I have 3-12-44 sf recital are very clear 1/2 mildot with plenty of aim point for air riffle same with the glass ,very clear, come with flip up scope caps and a very nice side wheel which is very handy indeed ,specially with Addon NV from CRS . Normally these side wheels are far to big but this one is about 50mm Spec is on par with Hawke vantage 3-12-44 sf but has no side wheel . IMO it is just as good as the Hawke if not better and about £70-75 cheaper
If any one is looking for a new scope , defiantly have a look at Discovery scopes https://discoveryoptics.co.uk/vt-z-sf-range/
