Continuity mistake: When El Blanco is outside Burt's home, and leaves, there isn't any hole in the ground after him. Later, in the movie, when El Blanco gets underneath the earth, he leaves a big hole after him. Why wasn't it like that the first time?
Continuity mistake: When Burt is at the gas station, he makes change with the box top of the pump. he closes the box. Jack approaches to meet him and the shot cuts to Jack and the rock is all ready on top of the box. we cut back to Burt and he is placing the rock on top of the box.

Continuity mistake: In the first Tremors when driving into Perfection the city limits sign list the elevation as 2135 feet. In this film the same sign shows the elevation at 2835 feet. In subsequent films, including the TV show and the Tremors 4 prequel, the sign says 2135 feet again.
Continuity mistake: After Jack digs down to the graboid he throws the shovel down, the next shot the shovel has moved next to the chainsaw.

Continuity mistake: When the gang first meets an ass-blaster, it flies into the sky, circles back and flies down towards them, quickly. The camera angle changes to its point of view, and for several seconds the view does not change - as if he'd just stopped in mid-air.
Continuity mistake: When the government guys come into the store in the evening they arrive, the wall clock shows 8:20, but the head guy's watch shows 6:28.
Suggested correction: I can't remember the last time I went into a house and saw a working clock on the wall. Very simple to explain, they just haven't changed the battery in the clock due to sheer laziness.
