There are probably thousands of different ways to fish a buzzer depending on the buzzer, as with any fly or lure really

Ive fished em static mostly, but allowed them to drift with the wind under a bung, or very large foam bodied Daddy or Sedge Dry fly, alternatively if the fish have been further up in the water the Dry fly has been tied on the point with the buzzers fished on 2 droppers back towards the leader loop at about 3-4 foot distance and a 6" dropper, or a Daddy on the top dropper a Satanic on middle and a Sedge on point works very well indeed

again all left static or with a very very very slow retrieve, like a slow figure of 8 using 2 fingers

just to keep the line tight to the fly's. watching either the buoyant fly, bung or the end of the fly line which is always a floating line.
If however using an apps type bloodworm they fish better sometimes stripped back or rolypoly retrieve really fast bit like a blob really

problem is most people when they get back too re cast they lift straight off without waiting to see what has followed

result a boil where the fly just left the water

Always before recasting let the fly, lure, buzzer whatever hang before lifting off.
As Leon has said a simple alternative retrieve can sometimes trigger the fish into taking, lets face it natural buzzers do go up and down in the water, I start out with a simple count to 100 to allow the buzzers to sink to the maximum depth then just leave em static but keeping tight to them by retrieving the line a little , then next cast a slow figure of 8 retrieve, next retrieve would be a pull of about 6" then a rest then a pull of 6" continued, next a couple of figure of 8s then a pull of 6" followed by a rest to let buzzers sink again, alternate the retrieve can make all the difference as can changing the way you fish, a lot of people think they must cast to the middle of the lake straight out in order to catch a fish?
I have followed, well ok, tried to follow a rule that was showed to me a long time ago, instead of casting straight out as far as I can (which aint that far

) Cast around you from 9 to 3 (bank to bank) in an arc which really means you are covering a lot more water
