Assembly of this in the field will take only a minute or two.

First, carefully attach the 1-1/2 inch piece to the 4-inch piece with the drafting tape. This is the one step where you have to use care to insure that the 1-1/2 inch piece is at a right angle to the 4-inch piece and at the correct end. Remember measuring starts at the bottom of the 1-1/2 inch piece.

Next, slip the folded portion of the 3-inch piece over the 4-inch piece. Slide the paper clip over this portion to help in loosely securing it. The paper clip may need to be spread a little so as not to bind, just not so much as to be ineffective.

When completed it will look like a capital “F” with the lower arm movable to set measurements. See Figure I.

Always start with the caliper larger than the track so you do not damage the track while adjusting the caliper. Lay the caliper next to the track with the extended 1-1/2 inch piece very close to the top of the imprint. Slide the 3-inch piece up until it is even with the bottom of the track. The point of the 3-inch section will be at the measurement. Note this measurement in your field book and take several photographs to insure at least one good, clear photo. Good luck, we look forward to seeing your properly measured, photographed and documented finds from the field.
