Multiple factors come into play that may limit the maximum size of your course. Generally: Chase course size up to approximately 100' - Home Original up to 200'-300' & Home Plus courses up to 750'
Anything that adds a load, or "drag" to the system may affect the maximum course size you'll successfully run. Some examples (but not limited to):
Long grass, weeds, or debris such as leaves and sticks in the path of the line
Setup on an incline; the steeper the incline, the more load or drag
Adding more pulleys
Uneven ground, where the line would touch the high spots
Adjusting the line too tightly
Adding more than one flag, or using other lures like those that come in the critter pack
Bulky knots, particularly when tying the lure
