The tip below is not mine, but picked it up somewhere on this forum:
Bunkers from 50 yards and in requires 1 very simple calculation.
for 15-20 bunkers, no change. Hit it normal.
for 30-40 bunkers, multiply your distance by .3 (30%). Add that plus or minus elevation.
for 40-50 bunkers, multiply your distance by .375 (37,5%). Add that plus or minus elevation.
for 50-60 bunkers, multiply your distance by .4 (40%). Add that plus or minus elevation.
I have been using it for some time now and it's pretty accurate (at least for me).You may need some tweaking (depending on balls etc) and of course, you need to know your wedge distances related to percentage on the meter. But I assume you have those mapped out.
So, for your example: 33 yrds x 0.4 = 13.2.
Add that to your 33 yrd distance = 46.2
Add 4 ft uphill = 1.3 yrds
So a total of 46.2 + 1.3 = 47.5 yrds
Then you know what % to hit on your wedge, hit it clean and perhaps allow for some roll, you should get it close to the hole.
