From the descriptions, it sounds like Proximity and Finders Keypers do the same thing. It seems you can detect which hand someone is holding one of the devices. Is this accurate? If so, what are the advantages of getting Finders Keypers at the higher price?

I'm sure that this thread will be moved to Inner Thoughts.

Anyway, to answer your question, a friend of mine allowed me to test Finders Keypers, after he tested it on me. Whether the hand holding the gimmick is behind his back or not, or the object is left on the table while you're standing up, you get the same signal. When you raise your hand, holding the object, you get two different buzzes, depending on which size you hold it. The distance is great, really great. The transmitter chip is very small, and can be hidden in many, many other small objects, just like Proximity. I was so impressed that I asked him to set this one aside for me (I don't have the money to purchase it right now) and I will get it probably toward the end of October. I will be able to test it in many different ways. I'm pretty sure I will be able to create a routine with it, where a spectator is asked to choose between keeping the object or giving it to another person (if he does so, he will have to stretch his hand, and the second person will grab it). The nice thing is that, during the entire time, I can be far away from the spectators. That is what I wanted.

Isn't finders a key?

The other is a thing you can put in other things.

Actually a key fob, not a key.

let the difference be known.

Yes, but isn't the effect the same?

Basically a which hand. could easier and more natural with the finders. I always wanted one but they were never available. So I got a die instead.

So Finders Keepers can be a longer range effect? Thank you.
