You're assuming they are trainable...If I owned a casino the first thing I would do is train my PBs how to count.

Some company is marketing a glorified ruler for casino surveillance to keep track of the running count. That's just silly. And it won't help if a counter is not using the Hi-Lo method.
There's many more like him. Just saw a floor person advise a player not to split 9's against dealer 4. "Never break up a made hand".
Most players don't know how to play a pair of 9's including casino personal so he might be telling the player how he would play the hand.

I'm assuming they can add 1, 0, and -1.
yes, because multi billion dollar establishments that have swings daily of 100k+ and multi million dollar surveillance systems cant afford a computer to count
Device laws based on the Nevada model do not allow either the casino or the player to use any device to count cards in real time. If the casino uses this device to decide to order shuffles during play it could very well be illegal.
What morons would need that stupid stick? Many of our opponents, that's who. LOL.
Better off to assume in general that our opponents are smart and dedicated. But of course in reality this is often not the case. Just need to think through how most companies hire and treat their employees, its "expensive" retaining talented and experienced employees.
