How to Change the Measurements

Changing the size of the proportional measurement is easy, just clip it in the correct hole and use the ends to shrink or enlarge the scale. To change the proportions, you pull the little tab back to the side, away from the end that's forked. It comes off easily. Pull the peg off both sides and insert it into another hole - count the same number of holes on both pieces. Push the peg through your selected hole and slide the white plastic holder over it again till it snaps. Make sure that little ridge is sticking up and you can push it till the peg snaps into the far end of the notch. Then it's solid.

If you want to enlarge a small reference, move the legs till the small end of the X shaped tool is just touching the dimension you want to measure - say, the width of a head. Adjust it while it's on the reference. You can also do the same thing at arm's length holding it in front of you to look at a live model or static object you're drawing from life - as long as you don't move, the length of your arm is consistent and you'll get accurate relative proportions.

Without moving the legs, turn the X shaped Prospek so that the wide end is on your paper. Make tick marks where the points fall. This also lets you place your reference on the page easier - the proportion remains consistent wherever you put the wide end of the Prospek so you can decide to move the head farther from the edge of the paper or make it off center easier.

The legs move easily and stay at the same proportion once moved unless you move them again. Friction holds them firmly in place no matter how many times I use this little handy tool.

If you want to reduce a large subject, just reverse the process. Use the wide end of the tool to measure your object and the smaller end to make your tick marks on the paper. Once you have the tick marks in place, connect the dots with a freehand line.
