Sandman's scoop looks very good for the job. It has the right angle to the scoop and a sturdy handle for lifting the load.
When buying a sand scoop, remember that the angle of the scoop to the handle is important. You want a sand scoop with an angle that will work well when pulled towards you.
First photo. Good angle for a sand scoop. Notice the angle of the scoop compared to the handle. Pulling it towards you will be easier, and it will hold the goodies inside the scoop better.
The next scoop is angled poorly. The handle will have to be held at an awkward angle in order to pull the scoop towards you. And you won't be able to use your foot to dig it into the sand deeper (if the target is deep). Not a good design, IMHO.
Basically, the angle made between the scoop head and the scoop handle should be less than 90 degrees -- for ease of use. An angle greater than 90 degrees will make the scoop hard to manipulate, especially when used in water or wet sand.
