Acurasee Circle Target (Actual Size: 8' x 8')

Circle Target: A player is given 4 points for hitting the center circle, or bullseye, of the Circle target. A player is given 3 points for hitting the ring that directly surrounds the bulls-eye, 2 points for hitting the next outer ring, which is two rings over from the bulls-eye, and 1 point for hitting the most outer ring.

Acurasee Rectangle Target (Actual Size: 3.25' x 13.5')

Rectangle Target: A player is given 4 points for hitting the center strip of the Rectangle target, and 3 points for hitting either of the two outer strips of the Rectangle target.

Acurasee Scoreboard (Actual Size: 13.5' x 3') Must be purchased with target

The lower corner of the scoreboard will alternately display both the point total and the number of times each target section has been hit. If the LED power button on the side of the display is pressed and not held, the score display will light up for a period of five seconds for easier viewing.

1) On the side of the scoreboard, switch number 1 (Side Close Up) is the channel switch. Set the channel mode of the scoreboard to match the channel mode which you set on the transmitter. 2) On the side of the scoreboard, button number 4 (Side Close Up) is the power button. Press for 2 seconds to turn on the power.
3) There are five levels of volume. The volume can be adjusted with the buttons labeled 2 and 3. The speaker can be turned off by pressing the button labeled 3 until the volume is past the lowest level. The speaker can be turned on by pressing the button labeled 2.
4) If the speaker is on, you will hear one of four distinct sounds each time one of the four areas of the Circle target is hit. You will hear the expression “scorchin” at random times when the target is hit. You will hear one of two distinctive sounds each time one of the areas of the Rectangle target is hit. A total point announcement will also be broadcast when you equal or exceed a total point score threshold of 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 150, and 200 points. See Section III below for explanation on the point system.
5) To activate the flashing light feature, press the switch labeled 5, LED power switch, to the on position. This will activate one flashing light when a one-point area of the target is hit, two flashing lights when a two-point area of the target is hit, three flashing lights when a three-point area of the target is hit, and all four flashing lights when a four-point area of the target is hit. See Section III below for explanation on the point system. To turn the flashing light feedback feature off, press the switch labeled 5, LED power switch, to the off position.

TO BEGIN TO PLAY

1) Unroll target and place onto the desired location of the tennis court. For best results, brush the target flat against the court if there are any areas of the target that are rising up from the flat surface of the court.
2) Plug the wire from the target into the outlet of the transmitter.

3) Set the channel mode on the transmitter to channel 1 or 2. If there is a user of the Acurasee® System on the court next to you, set your channel to be different from the court next to you so that their target hits will not register a score on your scoreboard.
Position the scoreboard in a spot where the player can view the flashing light feedback and also where the scoreboard will not be in the way of the player’s practice session. See Below:

 

PRODUCT CARE • Top

  • Recharging: The charger light will display red when the scoreboard unit is charging. A green light will display when the scoreboard unit is fully charged. The target and transmitter do not need to be charged. The transmitter uses one standard 9 volt replaceable battery.
  • Do not jump on the target.
  • Remove the target, scoreboard, and transmitter immediately from the court and into a sheltered area in the event of rain, or the threat of rain.
  • When the scoreboard battery charge becomes too low, you will hear an announcement saying, “warning, battery low” from the scoreboard and the scoreboard will shut itself off. In the event this happens, recharge the scoreboard battery within one week to avoid a permanent decrease in the battery durability.
  • When you are finished using the Acurasee® Training System for the day, in order to prevent a permanent decrease in the battery durability: Charge the scoreboard battery in full. Turn off the scoreboard. Disconnect the transmitter from the target to prevent transmitter battery drain. Store all items at room temperature in a dry area.

CIRCLE TARGET SYSTEM • Top

Use of the Acurasee® Circle Target encourages players and coaches to think about the most important element in tennis – where will the shot hit the court.  The Circle Target encourages players to have a specific shot location in mind whenever they hit a stroke.


The Circle Target is particularly useful to train players in skill areas such as:

  • Hitting forehands, backhands, and volleys deep in the corners of the court (cross-court or down the line)
  • Hitting sharp angled shots
  • Hitting drop shots
  • Hitting serves to various locations in the service box

Since the Acurasee® Circle Target is a portable device, the target can be moved to any court location desired.  This enables practice in hitting to any specific location on the court. The Circle Target enhances drills for both players and instructors.  Due to the automatic, accurate feedback provided by the Circle Target, the coach can focus on how balls are fed and the players’ form in hitting shots.  The player can focus on shot production knowing that automatic feedback will be forthcoming.

CROSS-COURT FOREHAND DRILL • Top

One of the basic shots in tennis is the crosscourt forehand.  By placing the Acurasee® Circle Target with the center of the target on the desired court contact location, the player is taught to hit to a specific court location as opposed to simply hitting crosscourt.  See Figure 1 below:

Crosscourt Forehand Tennis Drill

DOWN THE LINE & SHARP ANGLE DRILLS • Top

The use of two Acurasee® Circle Targets provides opportunities for advanced drills. For example, players can be encouraged to alternate between down the line shots and sharp angles as depicted in Figure 2 below:

Down The Line | Sharp Angle Drill
  • Do not allow players to alter their pace or form in an attempt to achieve greater accuracy. Insist that they hit with the pace and form you want to see in match play.
  • Devote part of each drill session to a standard drill that can be replicated each session for the purpose of monitoring progress.  Record scores under this standard condition and chart the results over time (refer to the section on charting Acurasee® results). Players enjoy seeing written records of their progress.
  • If you are involved with a tennis club, post the top 5 scores for different types of shots.
  • If you are involved with a tennis club, provide rewards for categories such as the top score each day and the most improved score.

SERVING FROM THE DEUCE SIDE DRILL • Top

The 8-foot  Acurasee® Circle Target is particularly well suited as a training device to develop placement accuracy for serves.  Figure 3 illustrates placement of the 8-foot target to teach a right-handed player to pull the service returner off the court when serving from the deuce side:

Serving From the Deuce Side Drill

RECTANGLE TARGET SYSTEM • Top

Use of the Acurasee® Rectangle Target System encourages players and coaches to think about the most important element in tennis – where will the shot hit the court.  The Rectangle Target System encourages players to have a specific shot location in mind whenever they hit a stroke. The Rectangle Target is particularly useful to train players in skill areas such as:

  • Serves deep in the service box
  • Serves close to the sidelines
  • Serves close to the service box “T”
  • Forehands, backhands, and volleys “down the line”
  • Deep shots near the baseline
  • Angled crosscourt shots close to the line
  • Drop shots to designated locations

Since the Rectangle Target is a portable device, the target can be moved to any court location desired. This enables practice in hitting to any specific location on the court. The system enhances drills for both players and instructors.  Due to the automatic, accurate feedback provided by Acurasee® Rectangle Target, the coach can focus on how balls are fed and the players’ form in hitting shots.  The player can focus on shot production knowing that automatic feedback will be forthcoming.

DEEP SERVE DRILLS • Top

An example of a drill using the Acurasee® Rectangle Target to train players to hit serves deep in the service box is shown in Figure 4.  In this example, the player is of moderate ability, so the Rectangle Target is placed well within the “out” line.  This teaches the player to hit deep while minimizing balls hit too deep.  As the player’s ability to serve to locations improves, the coach would move the target deeper into the service box.

Deep Serve Drills

DOWN THE LINE BACKHAND DRILLS • Top

Figure 6 shows the placement of two Acurasee® Rectangle Targets to develop a right-handed player’s accuracy in hitting down-the-line backhands.  In this instance it is an advanced player so two Rectangle Targets are placed with their outer edge covering the line.

Down the Line Backhands

COMBINATION CROSS-COURT & DOWN THE LINE BACKHANDS • Top

The Acurasee® Rectangle Target, when combined with the Acurasee® Circle Target, can be used in a wide variety of drills to teach players to hit specific court locations. One example of a combination drill is shown in Figure 8.  In this drill, the player is taught to hit either down the line or crosscourt from the same hitting location while disguising their target location.  The coach, observing from across the player, can concentrate and comment on stroke form and quality of the disguise while the Circle Target and Rectangle Target automatically record results.

Combination Cross-Court | Down the Line Backhands

The variety of drills enhanced by the use of Acurasee® Rectangle Target is unlimited. Listed below are a few suggestions regarding drills based from our extensive experience with the system. 

  • Encourage players to return to a central court position after each shot with proper speed and footwork. This will best mimic actual match conditions.
  • Do not allow players to alter their pace or form in an attempt to achieve greater accuracy. Insist that they hit with the pace and form you want to see in match play.
  • Devote part of each drill session to a standard drill that can be replicated each session for the purpose of monitoring progress. Record scores under this standard condition and chart the results over time (refer to the section on charting Acurasee® results). Players enjoy seeing written records of their progress.
  • When players achieve a high level of accuracy, consider increasing difficulty by altering the ball feeding method and/or target location (such as closer to the sideline, deeper in the court, etc.).  
  • If you are involved with a tennis club, post the top 5 scores for different types of shots.
  • If you are involved with a tennis club, provide rewards for categories such as the top score each day and the most improved score.

DEEP SERVICE LINE & DOWN THE MIDDLE SERVE DRILLS • Top

The Acurasee® Rectangle Target is also highly effective in training players to hit serves down the middle, also known as down the “T”.  The use of two Acurasee® Rectangle Targets can be used to alternate between deep service line serves and down the middle serves.  See Figure 5:

Deep Service Line Serves | Down The Middle Serves

HITTING DEEP BALL DRILLS • Top

The Acurasee® Rectangle Target is ideally suited to improve a player’s ability to hit the ball deep. The use of two Rectangle targets will cover the entire length of the baseline. The target depth should be moved closer and closer to the baseline as the player’s skills improve. See Figure 7:

Hitting Deep Ball

CHARTING  RESULTS • Top

Another advantage of the Acurasee® System is its capability to produce data that can be used to monitor progress in a reliable manner. This enables the preparation of written records and charts to monitor the progress of a player.  For an example, see the chart below:


PLAYERS ACURASEE® RATING* FOR 100 CROSS-COURT FOREHANDS

Charting Result

Note that with the Acurasee® rating system an excellent shot can score more than one “point.” (See the section on operating the system).


In order for any progress chart to be reliable and valid, it is important to do the drill under similar conditions each day. Key variables include: 

  • How the balls are fed
  • Court conditions (wind, temperature, etc.)
  • Player stroke production

When charting progress, the Acurasee® Target should be placed in the exact same location each day. The instructor can feed balls at the same difficulty level and the player reminded to try and achieve accuracy using their best form and a consistent pace. If practice sessions are indoors this adds another dimension of reliable measurement by minimizing the influence of court conditions. If drills are being done outdoors, results on days with highly unusual conditions (extremely windy, cold, etc.) should not be compared to results from normal condition days, since player performance will probably be unduly influenced by conditions. The Acurasee® System should be used on unusual weather days, however, as a precise and  reliable means of demonstrating to players how to adjust their shots to the unusual conditions. Note that players can generate highly reliable progress charts by using the Acurasee® System with a ball machine or in practicing serves.


The Acurasee® System is designed to promote the development of tennis skills by incorporating basic principles that support the learning of psychomotor skills.  However, there is no substitute for proper coaching. We encourage players seeking advanced skills to use the system in conjunction with guidance from professional tennis instructors.  We are confident that the use of the system by professional instructors will enable them to devote more of their valuable time to the direct instruction of their students.
