Bunkers will play differently throughout the golf course. Based on their size, location to the green, the amount of play that they receive and where they are located in relation to sunlight, wind and shade will all affect the playing surfaces of the bunkers..
The photo below is an example of two bunkers, in close proximity, that might play differently.
The small bunker in front of red #1 green will likely be a bit "fluffier" than the bunker just behind it to the left of the green for two reasons. The bunker is very small and will "catch" more balls because it is in front of the green. Ball will roll to and accumulate in the very small area of the floor of the bunker. Numerous golf shots will result in more disturbed sand, more footprints and increased raking. The bunker located slightly behind and to the left of the green is located more in the shade and will slower to dry following a rainfall. Thus, both bunkers, constructed the same and with the exact same sand will play differently.
The video below is a good explanation of why all bunkers will not play consistently.
The aesthetics and playability of the new bunkers new bunkers are tremendous.
