I was actually thinking more of the Shocker Blackheart board - no tournament lock on that one. No tournament lock on the stock Shocker board for that matter.
You can't change the programming of the board without opening the grips, so as long as the grips are on the marker, it is tournament legal. Due to that, SP never included a tournament lock on their Shocker boards - not the only company that have taken that route to tournament legality either.
You shouldn't have tools on the field, so you shouldn't be able to open the grips mid game (SP have now released screws that allow you to open your grips without the use of tools, but those weren't around when these boards were designed) so your board should be secure as long as the grips are closed.
The fact that there are now tool-less grip screws kind of mucks that logic up.....
