NateChrony ExtremeBallistic Help

You didnt read the instructions, read the instructions.

Aim for an accuracy confidence score in the range of 90-100. 85-90 will ensure you are within 3-5fps of actual speed. Above this will be 0-2fps of actual speed, it is really sensitive by design.

Detection Error: A typical number for an air rifle pellet is 20-30 @1,000fps. If you get an alignment error with a number a low lower than this (<15), this indicates the sensors were blocked for a really short time, then you need to increase the sensitivity of the sensors (closer to the blocked/clear state).
If you get a number a lot larger (>50), this indicates the sensors were blocked for a really long time, then you need to perform the cleaning process.

Aim for either perfect alignment (no error), or an alignment error indicating the neighbouring sensor detected the pellet first, for example 2-6 is perfect, 2-7 is fine and indicates the neighbouring rear sensor detected the projectile first. 2-8 indicates either the shot wasnt straight through the unit, or the 2nd/8th sensor is too sensitive.

Below are the onboard LED flash sequences for the NateChrony, in order of bootup.

System Start

3 Long white flashes: Indicates that the NateChrony is starting up, from a power up or rebooted/reset

Environmental Sensor Check

• 1 fast blue: Checking the environmental sensor
• 2 fast green: Sensor OK
• 1 long red: Sensor check failed, Sensor not available
  
  

Update Mode

If you are performing an update:

• 2 fast blue: Entering update mode and starting the update
• 1 slow green: Update succeeded
• 2 slow red: Update failed
  
  

Wi-Fi Connect

If the NateChrony has been to configured to connect to an existing Wi-Fi access point:

• 3 fast blue: Attempting to connect to an existing Wi-Fi network
• 1 slow red: Connection attempt failed, could not connect to the configured existing network
• 2 fast green: Successfully connected to the configured Wi-Fi network
  
  

Running

• Solid white: OK, normal operation
• Solid blue: OK, normal operation & connected to existing Wi-Fi hotspot
• Solid red: Critical error
• Solid yellow: Sensor error

Cleaning Process

• Remove the NateChrony ExtremeBallistic & take it somewhere clean
• Blow some clean air and use a soft brush or cloth on the lower sensor emitters (5x thinys in the lower half)
• Blow some clean air inside the upper sensor covers
  

Thorough Cleaning Process

• Remove the NateChrony ExtremeBallistic & take it somewhere clean
• Remove the 2 top screws in the protection plate
• Remove the 2 side screws in the top cover
• Remove the top cover by genly pulling it upwards
• There are 4 silver screws in the top of the black cover that secure the sensor guides, remove these
• The plastic guides will drop/fall out below
• Check inside & clean the guides, a cotton tip works well
• Gently clean the 8x sensors in the upper portion with a soft cloth or brush, blow with clean air
• Replace the sensor covers & screw into place
• Replace the top cover, and 2 side screws
• Replace the 2 protection plate screws
  

Sensor/Alignment Errors

Do not worry too much, we made this device so you can REALLY dial it in for accuracy. If you’re not seeing 100% confidence and no alignment errors you can still be within 2-3fps of actual speeds.

The ExtremeBallistic uses the REAR of the pellet for the most realible detection, critical with airgun pellets - domes, pointed, wadcutters, .177 caliber can all perform a little different on the leading edge.

Alignment Errors: The alignment errors show which sensor detected the FRONT of the pellet first. This does not trigger the timing, which uses the rear of the pellet. Possible causes:

• You didnt shoot directly through the unit & were potentially shooting through it at an angle
• One sensor was more sensitive than the others (most common), if its a neighbouring sensor - no issues

Detection Errors: These occur when the accuracy confidence score drops below ~70%. It means that the projetile didnt “look the same” at the front and the rear sensors. Possible causes:

• Calibration required: the sensitivity of sensors is very different
• Cleaning required: multiple emitters or sensors are dirty & require cleaning

Cannot Connect to the Device

Make sure you follow the instructions!!! (yes, i get grumpy)
Ensure you follow these steps before reaching out for support:

• Turn off any VPN or other software that will stop you connecting to a http page on a LOCAL network
• Connect to the Chrony/Target/ExtremeBallistic Wi-Fi network (the device page is NOT on the internet, you MUST connect to the device)
• If using an apple device use the chrome browser
• Open the device page: http://192.168.4.1 or http://192.168.5.1 (if ballistic mode on a steadyshot/extremeballistic unit)
• Double check you are STILL connected to the device Wi-Fi (especially on apple products)
• Use a laptop or a PC instead of a phone/tablet
• Turn on airplane mode, then turn on Wi-Fi and connect
• Turn off mobile data, and try to connect and open the page
• If your mobile doesnt want to play & you dont like to turn off the settings - buy a super cheap android tablet! (this is why it doesnt have a screen, i’ll never beat the price of a cheap tablet, and you get a free tablet!)
• Perform a drop test with the supplied pellet, or use a large >30cal pellet/object
• If none of these resolve the issues, please reach out & tell me the resutl of each step above
  
  

Alignment issues

This happens when the pellet doesn’t pass both sensors the same way as expected. Perform the following checks:

• Ensure the adapter is inserted correctly in the Chrony and fastened with the side screw
• Ensure the adapter is correctly installed onto the barrel, fully screw or push the adapter on & ensure it does not wiggle/move
• Your barrel/moderator/shroud may not be concentric with the bore, remove any accessories and install the NateChrony directly to the barrel if possible
• Rotate the NateChrony 90 degress and test again, do this 3 times to see if it rectifies the issue
• Reach out and let us know
  
  
  

Sensor Error

Cause: One of the 8 sensors appears permanently blocked, can be due to calibration being required, dirt/fouling of the emitters on the lower board, or dirt/fouling of the sensors on the upper board.

Resolution:

• Perform the cleaning procedure on the lower board
• Perform the calibration procedure
• If there are still issues, clean the sensors on the upper board & re-calibrate
  
  

Random Shots Appear on the Screen

Cause: At least one of the front sensors, AND at least one of the rear sensors is too close to the blocked/clear state, it is triggering a shot. Resolution: Perform the calibration process - make sure you do it where the ExtremeBallistic will be used, make sure it is in the shade, and make sure after the sensor turns “clear” you do another 1/8th turn.

ExtremeBallistic randomly reboots Wi-Fi drops

Cause: One of the front sensors is too close to the blocked/clear state, it is triggering a shot.
Resolution: Perform the calibration process - make sure you do it where the ExtremeBallistic will be used, make sure it is in the shade, and make sure after the sensor turns “clear” you do another 1/8th turn.

ExtremeBallistic doesnt detect a shot

Cause: The sensors are not close enough to the blocked/clear state, they are not being blocked enough to detect a shot.

Resolution: Perform the calibration process - make sure you do it where the ExtremeBallistic will be used, make sure it is in the shade, and make sure after the sensor turns “clear” you do another 1/8th turn. If you do more than 1/8th turn (good for .177 caliber) more blocking of the sensors is needed to trigger a shot.
