Some of the old farts on here might recall a electronic Gizmo that uses a light beam to cut off a power powder trickler when the beam of scales reach the set weight. I recall seeing in in Target Gun and even Guns Review I recall. The first one the electronics were housed in a plastic tupperware type tube then as they got into production a new special casing was sourced.
Well now the one I saw being demonstrated in the clubhouse yesterday at Reepham Moor range is much improved and very professioanl looking. The price is not too bad either at just under £100.
A useful Gizmo if you have the room for it on the bench. As for me I will have to continue with the Mk1 Eyeball and a manual finger twiddled trickler or as have recently being used the Lee Powder Dippers and the scales.
