How powerful is the track

I'm working on a project which scenario is repair the Gasoline engine.

first of all, i'm going to detect my toolbox  by tracking Vumark. (i put the Vumark on top of toolbox.)

second, i'm going to detect my engine by doing model target.

The engine is on the opposite side of the toolbox, so you can't see it all at once.

While looking at the engine, arrow going to point out where the toolbox.

is this possible ?? How powerful is the track ?? and How long is the track??

PLEASE HELP me !!
