Welcome to Youna.com! We are glad you found us and we hope we can be of service to you.
Youna.com has been our online shopping platform since 1999. The site is serviced out of our 2 physical stores located in Southern California more exact would be City of San Diego store named "Electro-Optical Inst Co" which I started in 1989 and in the City of Colton which started in the 1970s as "Colton Camera" and later became known as "Colton Surveying Instruments".
Our experience has been maturing over those decades, supplying Land Surveyors, Engineers, and builders with some of their daily use tools, measuring instruments, and field supplies as well servicing, repairing, and calibration.
We promise to do our best to provide you with quality and secure service and product, so feel free to contact us any time with any questions or comments.
Please enjoy browsing around the store, we do have more than we listed, so if you don't see it, there is still a good chance we have it.
