Where to find the equipment

The 'net is a wonderful resource for finding things. I found out a great deal about the extent of Vernier probes and sensors that connect with our existing TI calculators. With the purchase of a couple of CBL's (Calculator-Based Laboratory™) and some probes, we could be off and running in no time. This could be quicker by purchasing probes that hook directly into the calculator. This is a decision that needs to be made before purchasing hardware.
