WGTS is an aid, not an official. Its role is to make the jack, the bowls, and the measured relationship easier for the group to read together.
Start with a shared view.
A close head becomes harder to discuss when everyone is looking from a different angle. The camera view gives the group a common reference before the distance appears. That shared reference matters as much as the final number.
The person holding the phone can help by narrating the short sequence: framing the head, confirming the read, and showing the result. There is no need to hide the process or treat the device as a black box.
Agree on the role before the measure.
Clubs already have their own match procedures, markers, umpires, and trusted habits. A digital tool should fit around those practices. Before using it in a close call, decide who will hold the phone, who will confirm the head is ready, and how the result will be shared.
That small agreement keeps the tool in its proper place. It supports the call; it does not invent a new authority.
Use a routine everyone can repeat.
- Pause the head and make sure the bowls are clear to view.
- Choose one person to operate the phone.
- Keep the screen visible while the head is framed.
- Read the result aloud and show it to the players.
- Return to the club’s normal process if the view is unclear.
A repeatable routine removes uncertainty without adding ceremony. New players can follow it, and experienced players can see exactly where the device fits.
Keep a human path open.
No camera view will be right for every head, device, or lighting condition. A clear interface should say when it cannot confirm the read, and the group should be able to return to its established method without friction.
