Setting Up the Coaxial Cable for a Shot with the ShotTrack VoD Unit
Using the ShotTrack VoD unit is straightforward, especially with a few best practices to achieve optimal results. Our recommended steps are marked on the RG59 Mini cable we supply, chosen for its usability and convenience. While our preferred cable is the RG59 Mini, any high-quality, 75-ohm coaxial cable will work.
Recommended Cable Types:
RG6U – Highest quality but bulkier; best suited for larger-diameter holes.
RG59 – Compact yet versatile; a mid-sized option.
RG59 Mini – 3.7mm diameter; lightweight and easy to handle, ideal for small-diameter holes and underground use (the following instructions are printed on all our RG59-Mini cables)
Instructions for Deploying ShotTrack VoD Cable Down Blast Holes
A: Create a Trigger Loop
The ShotTrack VoD unit needs a quick 2m reduction in cable length to trigger. Form a 2m loop near the end of the cable. This loop allows the cable to be “cut” by the blast, activating the unit.
B: Secure and Lower the Cable
After creating the loop, tape the cable to the booster or attach a weight to lower it into the hole. Ensure the cable is taut and free of kinks or twists.
Position the cable end in the initiating hole, ideally one of the first firing holes.
C: Place Cable in Subsequent Holes
For each additional hole, insert the cable so it runs in and out. Use a loose cable tie and weight to drop the cable easily. These holes should be later in the firing sequence.
D: Allow for Cable Slack
As the blast initiates, ground movement may pull the cable between holes. To prevent snapping, leave enough slack between each hole and the unit.
E: Record Cable Length Markers
Note the length markers on the cable as it enters and exits each hole. These markings help identify data points or troubleshoot issues in case of a misfire.
F: Ensure Sufficient Slack Throughout
Leave slack in all areas where ground movement may pull the cable, from the unit to the first hole and between all other holes.
