What is the difference between the deluxe model and the drop-tine model?

What are the advantages of those two over the standard model?

Rangeball

The deluxe has graduated marks, the drop tine doesn't. Both adjust easily in the vertical and horizontal planes.

The regular is much harder to get lined up in both planes, but once set it does the job. Walmart carries this model

Basically, you spend a bit more cabbage to save some P in the A time...
