3M 1710 Overhead Projector Overview
The 3M 7100 overhead projector is as fine a projection unit as most anyone could want. Well designed, it is extremely durable, with attention given to portability. It is ready to go once you remove it from the box--there is nothing that needs to be assembled. Simple to use, one switch turns the device on and off.
The post assembly, which holds the projection head aloft, has an elbow joint that adjusts with the turn of a knob, operating the focus. The closed projection head is sleek and strong--in keeping with the unit as a whole. One of the things that sets this model apart from others is the inclusion of a backup projection lamp. A covered control panel allows you to change over to a second projection lamp if the one in use has burned out, which is a most reassuring feature (typical lifespan for the lamps required is about 130 hours). The lamp bulb is easily changed, and the power cord can be neatly wrapped around twin brackets at the bottom front.
The instruction manual is simple and straightforward and is primarily useful for its easy troubleshooting tips, should any problems arise. It even covers such things as a faulty bulb or projecting onto a screen that is not perpendicular to the projector. The 3M 7100 model would be ideal for classrooms, business meetings, or large presentations of any sort. --David Greenberger
