The Go Direct® Science Sensors and Interfaces, developed and manufactured by Vernier Science Education, are a family of modern, all-in-one sensors built for real-time data collection in classrooms and labs. These devices feature multiple types of connectivity, including the ability to communicate directly with calculators such as the TI-84 Plus CE, the TI-Nspire CX II, and the Ti-Nspire CX II CAS. Students can collect, graph, and analyze scientific data through software like Vernier’s free Graphical Analysis apps or TI calculator integrations. Designed for hands-on experimentation in subjects like chemistry, physics, and environmental science, the sensors include built-in rechargeable batteries, many different sensor types, and are simple to use, which helps support STEM learning at all levels. Go Direct sensors streamline experiments, enhance engagement, and help students make real-world connections through science.

I have ordered calculators from Underwood Distributing for so many years that I have last track of the time. They are always quick to answer my emails and they get the product I need shipped out asap! 10/10 recommend Underwood!
Fantastic company and product. Stellar to work with year after year.
The Ti 84 launchpad board and RGB led board are hard to find new for just a single user and definitely not at such a good price. Prompt shipping and everything arrived well packed. Seriously great source if you are looking for small quantity at great value. Thanks!
I teach middle school and wanted reliable calculators, at a good priced, and in a distinct color so everyone knows who they belong to. They were well-packed and arrived quickly! I am so pleased with my purchase and will keep this company in mind for future needs.
I have be searching for this cable for over a year! I went to Circuit City, Best Buy and Amazon. NONE of them had this cable. FINALLY I found this cable and I bought in on a desperate hope that it would be the right cable. IT IS!!!! THIS CABLE WORKS FOR CALCULATOR to CALCULATOR DATA TRANSFER!!!
My current order of graphing calculators was placed and ordered so quickly. Underwood Distributing Company made this process easy and I appreciate the timeliness along with the great price. THANKS!
Underwood Distributing was so easy to work with on getting calculators for my classroom! They were so nice and kept me up-to-date with the status of my order. I received my order very quickly, and I am very happy with the purchase.
I am very satisfied with the promptness and diligence in which my order was processed. The teachers were able to receive their needed supplies on time.
I needed to replace a calculator from a Teacher Pack. Found the perfect replacement here. It works great. Exactly what I needed. Delivery was very quick.
Great communication, Karen and Jacob took good care of us. Shipping was fast. Product is excellent quality. Thank you. -Arnold
Works perfectly! Couldn’t find these cables anywhere but once I saw them so reasonably priced here I couldn’t say no! More than happy with my purchase! Thank you!
I search something and they have it, sent an email about it with instant response and Jake helped me order it in a few mins, product arrived much earlier than I expect and in excellent condition.
I ordered a calculator late Monday night that I needed by Wednesday. I communicated with Jake several times via email and once on the phone throughout the next day. Had my calculator before noon on Wednesday. Every response to me was quick, helpful, and very courteous!! Great company and customer service. I will order through them in the future and highly recommend others to do the same.
I am a first-time customer but will definitely purchase items from Underwood Distributing Company if I have a need for their products in the future. I purchased an authentic Texas Instruments battery and replacement charging cord for a TI-84 calculator. The cost of these two name brand products with shipping was still less than the cost of the battery alone through Amazon! Each item came wrapped individually in bubble wrap then placed in a bubble wrap mailer. Shipping was also very quick. I can't say enough about how impressed I have been from start to finish with my purchase.
