Inside Spread (At Widest Point) – Inside spread is done by holding the clip of the tape against the inside of the beam on one side, while the outside of the neck of the Rackulator is held on the inside of the beam on the other side. Be sure current measurement is zeroed. The lock button is pushed and the measurement is taken while the tape is manually pushed back in. The width of the clip and the neck of the Rackulator are automatically added in. (See Scoring Instructions)
Circumference – Circumference is done by using the tape. Pull out the tape and put it around the antler where the measurement is taken. Hook the clip on the tape, while holding the tape around the beam; push the Rackulator against the beam. This will align the tape straight into the Rackulator where the clip and Rackulator meet. This will avoid kinking of the tape. Be sure current measurement is zeroed. The lock button is pushed and the measurement is taken while the tape is manually pushed back in. It is necessary to pull out more tape to release the clip. This will not alter the measurement. The length of the clip will automatically be added in. (See Scoring Instructions)
Beam – Measurement taken with the wheel, starting at the tip of the beam following the center along the outer curve of the beam to the lowest point of the burr. (See Scoring Instructions)
Tines – Tines should be marked off with a pencil line. Use wheel starting at tip of tine, roll down center and outer curve of tine stopping at intersection of beam and tine. (See Scoring Instructions)
Wheel – The wheel will add while rolling in either direction. If you change directions it will minus.
Tape Measure – The tape measure can be used as an electronic tape by pushing the lock button while the tape is out. It is measured by the wheel when the tape is manually pushed back in. While using the tape electronically, the numbers on the tape will not coincide with the numbers on the screen. The tape can be used to make measurements manually or electronically. Manual measurements are made in the same manner as with a regular tape measure. The results may then be entered into the Rackulator by rolling the wheel manually until the display shows the desired measurement. It is necessary to assist tape measure retraction when lock is engaged by manually pushing the tape back in.
Lock Button – Pushing lock button toward wheel engages tape. Pushing away from wheel disengages tape.
Pointer – Start and finish point alignment.
Beeper – The beeper will sound while the wheel is in motion.
Computer Interface Jack – Link to computer (requires optional software & cable).
Extra – Extra is a mode that was put in the Rackulator for multipurpose use. You can use this mode at any time while scoring and it will not add in any measurement taken. This mode can be used to find the proper location for circumference measurements on a 4 X 4 whitetail. The 4th circumference is taken halfway between the last tine and the point of the main beam. You can roll this distance with the wheel. Push the ÷ 2 button, remember that figure, push clear, roll from beam tip until that figure appears on the screen, now mark that circumference location and take measurement. This method also works on horned game to find the quarter measurements by pushing the ÷ 2 button twice
