Tracer Projector Drawing Murals More

The lens on the EZ Tracer are not very powerful, so when I attempt to project an effigy onto a canvas it is either too big or too small.

i must say, i am slightly disappointed. the zoom feature, if any, is not existent. i thought that you would be capable to twist & turn 4 dandier accuracy. NOPE, you have to push & pull. plus you cannot in truth make the effigy super big, as i was hoping for. i wonder if the more expensive ones may do this.
