What Si-Tex does

SI-TEX Marine Electronics is a privately held, US-based marine electronics company founded in 1975 and headquartered in Riverhead, New York, with a staff of roughly 11-50 employees. The company designs and markets marine navigation and fishfinding hardware for both recreational boaters and commercial fishermen/professional mariners worldwide, spanning small center-console skiffs and sailboats through IMO-certified equipment for tugboats, workboats, ferries and high-seas commercial vessels. Its portfolio covers GPS chartplotters, sonar/fishfinders and echo sounders, radar systems, AIS transceivers (Class A and Class B/SO), autopilots and autopilot drive units, heading sensors/satellite compasses, digital displays, and stabilized binoculars.

The company operates two product lines: SI-TEX-branded products (NavPro, SVS, ORION, EXPLORER chartplotters; SP-series autopilots; MDA/SAS AIS; T-series radar; CVS/ES/SVS sonar) and Koden-branded professional/commercial products manufactured by Japanese OEM Koden Electronics Co., Ltd. (established 1947, with a US sales/service presence since 1981). Products embed proprietary technologies including Guardian anti-grounding, COAST (differential position hold), Rmax (AIS range optimization), Hyper-Digital Processing radar, Koden Digital Filtering and DSP sonar filtering, and Sona-Tone fish identification. Devices interoperate through NMEA-0183 and NMEA-2000 protocols and support C-MAP, Navionics and Polaris cartography, with numerous FCC, USCG, IEC, SOLAS and IMO Wheelmark certifications.

The business model is hardware sales, monetized through a network of authorized dealers and marine specialty retailers (accessed via a 'Where To Buy' locator) plus a direct-to-consumer outlet shop for refurbished/certified pre-owned equipment. Pricing is unit-based and spans entry-level chartplotters to commercial systems (e.g., SP-38 commercial autopilot from $2,699 MSRP; Sirius 12 binoculars at $699), supplemented by manufacturer rebate programs ($150-$350) that bundle NavPro chartplotters with Echonautics transducers. Revenue is supplemented by accessories such as transducers, remote controls and antennas.

Broad incumbents

• Garmin: Global leader in marine electronics (GPSMAP chartplotters, Fantom radar, Panoptix sonar, AIS) with far broader portfolio across fitness, aviation, and outdoor. Directly competes with SI-TEX across recreational chartplotter, sonar, and radar categories while also dominating OEM boat-builder integrations.

Direct peers

• Raymarine: Specialist marine electronics brand (Axiom MFDs, Quantum radar, HyperVision sonar, AIS) under Teledyne FLIR. Closely comparable product line to SI-TEX across chartplotters, radar, sonar, and AIS, serving overlapping recreational and light-commercial segments.
• Furuno: Long-established Japanese marine electronics manufacturer (radar, sonar, GPS, AIS) with strong commercial-fishing and IMO-grade product lines. Closely parallels Koden/SI-TEX in professional fishing, IMO compliance, and transducer-rich echo sounder portfolios.
• Icom: Marine VHF and AIS specialist (M605, M510, MA-510TR Class B AIS) with overlapping communications and AIS transceiver product lines. Comparable NMEA integration ecosystem and recreational-to-commercial customer base.
• Humminbird: Johnson Outdoors-owned marine electronics brand specializing in fishfinders, chartplotters (HELIX, SOLIX), and sonar (MEGA Imaging). Directly competes with SI-TEX's SVS and CVS sonar/sonar-combo product lines in the recreational fishing segment.
• Navico (Simrad / Lowrance / B&G): Multi-brand marine electronics conglomerate whose Simrad, Lowrance, and B&G lines cover the recreational-to-commercial spectrum — directly comparable to SI-TEX's recreational/commercial split and overlapping chartplotter/sonar/radar feature set.

Emerging players

• Navionics (Garmin): Marine electronic charting and bathymetric data provider integrated into SI-TEX chartplotters. Strategic partner/comparable in chart data and SonarChart bathymetric recording capabilities layered on chartplotter hardware.
• C-MAP: Marine cartography provider whose C-MAP MAX/NT+ and C-MAP 4D chart data is integrated into SI-TEX NavPro, TRAWL PLOT, and EXPLORER NavPro systems via the Guardian anti-grounding feature. Direct technology/integration partnership parallel.

Others

• Airmar Technology: Marine transducer manufacturer whose CHIRP transducers with TX ID are integrated with SI-TEX NavPro fishfinder systems. Comparable in transducer/sensor technology and an enabling supplier within SI-TEX's sonar stack rather than a direct competitor.
• Echonautics: Transducer technology partner supplying thru-hull transducers for SI-TEX NavPro chartplotter/sonar bundles (CB101D, BT70 series). Closely tied commercially via rebate program; comparable in transducer technology but not a chartplotter competitor.
