Commercial captains, sportfishermen, cruisers, and sailors around the world trust SI‑TEX because our products are engineered for real conditions, real work, and real results.
Our lineup covers the full spectrum of modern marine electronics — professional‑grade radar, high‑performance echosounders, advanced MFD chartplotter/sounder/radar systems, precision GPS navigation, heading sensors, autopilots, VHF communications, and more. Every SI‑TEX product is backed by a 2‑Year Warranty and supported by our Long Island, New York‑based Service Department, delivering the kind of customer care only a seasoned, hands‑on team can provide.
SI‑TEX is built on people who know this industry inside and out.
President Ted Bodtmann has been shaping marine electronics since 1967 and has been part of SI‑TEX from day one.
Across five decades, our mission hasn’t changed: deliver the features boaters actually need, the durability they expect, and the value they appreciate. Every new SI‑TEX product carries that legacy forward with modern performance, intuitive operation, and the toughness our name is known for.
