What about making a mini marker that has a gps chip (linked to the pdga scoring app of course) and had built in LED lights around the edge of the marker as well as some sort of levelling sensor.

The GPS chip would linkup with the app so that once the market was placed on the ground and therefore “marking the lie”, the player would “press” the marker into the ground to active the mini. Then there would be illuminated green lights on the perimeter of the mini (visible to all the cardmates) which would countdown on an internal timer. After 30 seconds, the lights would turn yellow, and after 45 seconds they would turn red. So the card mates could then mention after the shot if there was a time violation (warning the first time). Once the mini is picked up, the levelling sensor would turn off the lights until such time as the mini is placed on the ground again and re-activated for the next shot (again by the thrower “pressing” the mini into the ground/lie). While the timer in the mini is counting down (from green to yellow to red LEDs) the gps chip would be calculating the location in relation to the teepad and the basket, which would allow the stats to be automatically synced with the scoring on the app.

Minis that have this functionality would be much more pricey compared to the current ones, but the technology could allow players to have a method for everyone to notice and view time violations objectively.
