CBR 2
In most situations, the CBR 2 (CBR2) is the best choice. The CBR 2 (Calculator Based Ranger) was developed primarily for math teachers who want to quickly collect data. It connects directly to TI-84 Plus and TI-Nspire calculators to collect motion data.

Motion Detector
A Motion Detector (MD-BTD) can be used with TI calculators, but the motion detector requires an interface. These interfaces do not work will all calculators, and some interfaces have been discontinued. Unless you already have an interface, do not purchase this motion detector for use with your calculator.
Calculator Interfaces that work with the Motion Detector
* This interface does not work with newer TI calculators (e.g., TI-84 Plus CE). See supported calculators.
