Incorrect. They are turned on by passing past a Magnet that you attach to your shelf or riser so the arrow passes by it. After it's been shot and activated to turn it off you simply put the nock back by the magnet and it turns off. The magnet and nock are 2 seperate items.

If you did read the tracer nock thread, you'll see that of the first 2 pack that I bought, the first on failed. It was quickly replaced free of charge and they let me keep the one good one from the 2 pack. I have since shot the 3 I have hundreds of times without 1 failure. As of Now, I'm back on the bandwagon due to great Customer service (through Cabelas, NOT EASTON who's customer service STINKS!) and a product that works as advertised.
