Our Story

Transitional Systems Mfg. was born out of an irrigation service and repair business in 1985. It was originally named The Sprinkler Man by the founder Jim Geiger. While the TSM acronym remained - the mission changed. After years of successfully repairing irrigation systems with a product he developed, it was offered to other irrigation professionals. It was so well received that Jim needed to manufacture it in larger volume. That product was the original Doubler.

Doubler was designed to eliminate the time and expense of fixing broken wires by allowing you to bypass them all together. An all day job could now be done in less than an hour. Doublers' ease of use and durability led to it being used in greater numbers and became the standard in the industry as the solution to broken field wires. No digging or trenching required! Many backs were saved! 🙂

In 1994, Sean Siebern came on board as an assembly technician and to handle service calls. He soon began working on product design and development as well. As the company and products grew, the TSM name came to be synonymous with solving problems in the irrigation industry. TSM was incorporated in 2001 with Sean acting as VP/COO and by October 2005 he was named as President/CEO.

Over the years we have received many calls from people just like you - many looking for solutions or needing help troubleshooting irrigation systems. We always listen to our customers' needs and your input has even resulted in new products and design updates. As the technologies in the irrigation industry have evolved over time, TSM has updated its products to make use of these new technologies. We continue to invest heavily in R&D to refine and update designs ensuring long service life and equipment compatibility.
