These are the questions we get asked the most. And we've got the answers!
For more in-depth explanations on maintaining your TechnoHUNT system, please refer to our user manuals, available on the downloads page.
Make sure that your system is set to use the "2 sensor" setting. (On TH100 system, this will be the default setting. For TH300 systems, it is likely that your system is set to "4 sensor" mode so it will need to be temporarily changed while the kids shoot.)
This will tell the system to only use the down-range sensors. Anyone can now shoot from any distance. However the True Yardage, Wind, and multi-player features cannot be used while in this mode.
You can add and remove players from your league at any time.
Select the League you want to play. Under the current list of names already in that league is a checkbox that says 'Show Only Players In League'. Uncheck this box, and your complete database will be shown. Simply select the new player to shoot the league, start the game, and he is now saved in that league.
Generally, your TechnoHUNT system only needs to be calibrated if it is mistracking arrows. There is no need to do a regular re-calibration of the system. However, if you make any alignment changes to the sensors or to the projector, it's a good idea to re-calibrate.
Your graphs should be checked every morning before shooting the system. Any trouble spots (dips below 60 or thin spikes) should be taken care of immediately.
Additionally, your reflective tape should be wiped down every morning (never use any cleaning solution), and any scratches or bad scuff marks should be patched.
Keeping the threads on your screen trimmed down will also help your TechnoHUNT system perform optimally.
A good graph will have a definite beginning and end, not a 'curve' at either end. It will be free of any dips below 60 and thin spikes. It should have an overall light level that stays above the 60 mark, generally between the 512 and 1536 marks.
There are a few basic steps you can take to keep your TechnoHUNT system working like it should. These maintenance steps take very little time, and can make a huge difference in how your system operates.
1) Keep your tape clean! Wipe down your tape each morning before your shooters come in. You may even want to check it throughout the day to ensure that dirt, fletchings, etc., are not on the tape. Don't let anyone walk on the tape! A dry soft cloth works well to wipe the tape down. If needed, a damp cloth can be used, just be sure to follow it immediately with a dry cloth to avoid any water spots. Never Use Any Cleaning Solution (Windex, etc.) On The Tape! Cleaning solutions have chemicals that can reduce the reflectiveness of the tape.
2) Check your graphs!! It takes only a couple of minutes to pull up your graphs and ensure there are no dips or spikes that might confuse the system. It takes much longer to have to reboot the system and start a game over if errors start to occur in the middle of a game.
3) Keep the screen threads trimmed! If the threads are more than a couple of inches long, they can enter the sensor array after an arrow hits the screen, potentially causing the system to mistrack the shot.
The average TechnoHUNT scenario lasts between 15-25 seconds. This comes out to around 600-800 frames of video. Hit-zones are drawn on every frame around the animals' body area, vital area, heart, and in some cases (mostly small game) the head. Body shots are worth 5 points, Vital or kill shots are worth 8 points, and Bullseyes (Heart and sometimes Head shots) are worth 10. Please note that not all scenarios present a valid heart shot, and thus may not have a Bullseye. Neck shots and limb shots are always counted as misses. While most small game animals have a Hit-zone drawn around the head and body, there is never a Hit-zone drawn around the neck. Hitting the animal between the head and the body will result in a miss.
We have found that over time the bungee cord is stretching and relaxing. This is normal. However, if the screen relaxes too much it can cause problems in tracking the arrows, especially shots to the middle of the screen. A general rule-of-thumb is that if the screen presses in with an arrow, more than 4” with light pressure, then it is time to tighten the screen. Below are the instructions to do this.
- Untie all the knots at the ends of the Bungee Cord. (Notice how they are tied so you can tie them again, Take a picture if possible).
- Starting in the middle at the top of the screen, grab the bungee between the 1st space between the eyebolt screws on the right hand side of the middle.
- Pull until tight (not too tight: just enough to stretch the bungee down to 3/8” diameter).
- Hold the slack that you have pulled in your left hand and grab the bungee in the next space with your right hand and pull. Allow the slack that you are holding in your left hand to pass through into the right hand.
- Repeat this procedure until you get to the end of the rope.
- When you are finished with the first rope start again in the middle at the top but this time go to your left.
- When you have tightened the entire screen, check the screen for tightness by pushing in the middle. The screen should push in approximately 2-4 inches.

This number refers to how far off the calibration is from being "perfect". For every ten points, the system will be off by an inch. Therefore, the lower the calibration result number, the better the tracking will be.
i.e. A calibration rating of 10.00 is equal to 1 inch off for arrow marking. 5.263 equals about 1/2 inch off for arrow marking.
The lower the calibration number (closer to zero), the tighter the tolerance. Don't worry if the calibration rating is not exactly 0. A low number (anywhere from 0 to 10) will be perfectly adequate for the operation of your TechnoHUNT system. If your calibration scores a number higher than 10, the calibration will fail. If this happens, check your graphs for spikes.
It should also be noted that using an arrow with a smaller diameter for the calibration process can help with a more accurate calibration.
We strongly suggest unplugging all components of the TechnoHUNT system before an electrical storm. This is especially important for the 125' and 90' Cat5 cables that run from your computer to your Master sensors. Both ends of these should be unplugged.
Anything connected to a wall outlet should remain disconnected until you are certain it is safe to plug them back in. Your warranty will not cover damage caused by an electrical storm, as it is considered an act of nature.
It is a good idea to make a habit of unplugging the system at the close of the day just to be safe, especially if a storm is nearby. Even a powered-off system is at risk if it is still connected to an outlet or if the Cat5 cables are still connected at either end. The Cat5 cables can act like antennas for picking up static electricity and can easily harm your system.
The mouse arrow may show up on the video during gameplay. This can occur from having reset your game's defaults. Use the following directions, or, for a more detailed description of how to turn this feature back off, download the following document:

At the TechnoHUNT start-up screen, select "Options". On the next screen, click on "Game Options", then select "Advanced Options". This will cause a window to pop up, asking whether you would like to continue. Select "Yes". Another window will appear with four options. Choose "Change Registry". In the next window, make sure that the white box in front of "Mouse Clicks On" is empty. Click "Apply" at the bottom of the window, then choose "OK" which will close the window.
Summary: Downrange sensors (in front of your screen) cannot communicate. Uprange sensors may or may not work.
Error Message: "Sensor 3 not responding on Port COM4" in graphs
Summary: Downrange sensors communicate, but the uprange sensors don't.
Summary: Computer can't communicate with all the sensors.
- Sensors turned off
- Loose cable(s)
- Malfunctioning Sensor
- A second Atrack process running (confirm this in your task manager window, by pressing control, Alt, Delete keys simultaneously on your keyboard.)
After every game, you must, exit out of TechnoHUNT to the desktop, WAIT 10 SECONDS, and then double click on the “TechnoHunt Menu” icon to restart the game. Click on Launch and you are ready to play
If you do not do this the system may freeze.
Press these keys on your keyboard simultaneously; Control, Alt, Delete and end the drawing window only in the Task Manager window. Then quit or exit out of Technohunt and restart the Technohunt program to begin a game.
System confused means one of the following things happened:
Too much data (errant readings). Possible causes:
- high Sensor Sensitivity setting
- obstructions on tape [remove/clean/patch]
- cable hanging in array [tie cable up]
- vibration [reconstruct screen frame and sensors]
- electrical interference [remove fluorescent lights and appliances from the circuit and remove from proximity to sensors]
- loose screen [tighten bungee]
- screen threads [singe or cut loose threads]
- spider webs [clean]
Too little data (sensor(s) missed a shot) Possible causes:
- low Sensor Sensitivity setting
- misaligned sensor/s causing a blind spot
- misaligned array boards
- ambient light [eliminate light]
- Unintelligible data (can't figure out shot
Arrow shots do not register ("no shot" message when one was actually taken):
- Sensors out of alignment
- Sensor light level too low. Adjust sensor sensitivity.
- Dirty Tape
- Align sensors and recalibrate.
- Clean tape.
- Increase light level for respective sensor.
Arrow shots registers in wrong location:
- Out of calibration
- video image from projector is offset or has moved
- Run Calibration program
- Center the projector's image on the screen and then recalibrate
