Si-Tex Fishfinders, GPS & Chartplotters

Si-Tex Navigation and Fish-Finding Electronics

Si-Tex has been building marine electronics on Long Island, New York, since 1975, and its chartplotters and sounders reflect that long track record with working boats. The company describes its mission as delivering the features boaters actually need, with durability and value. In the Fishfinders, GPS & Chartplotters category, that approach shows up in practical combination units that put navigation and sonar on a single screen.

The SVS Series: Compact Chartplotter/Sounder Combos

The SVS line is built for boaters who want charting and fish-finding without a complicated installation. The SVS-560 is a compact chartplotter/fishfinder with a 5-inch high-resolution color LCD and LED backlighting. It is designed to suit vessels ranging from center console skiffs to sailboats and light commercial boats. Its GPS is compatible with multiple global satellite systems, including Galileo, Glonass and QZSS, which helps with fast, dependable position fixes.

Moving up in screen size, the SVS-760CF pairs a 600W dual-frequency echo sounder with an external 50-channel GPS antenna. The SVS-880CF offers an 8-inch display and can be configured as a chartplotter only or with built-in dual-frequency sonar. A 50/200 kHz setup is a sensible choice for anglers: the lower frequency reaches deeper water and gives wider coverage, while the higher frequency delivers sharper detail on bottom structure and fish targets.

NavPro: Hybrid-Touch Multifunction Displays

The NavPro family is Si-Tex's modern multifunction platform. The NavPro 900F has a 9-inch high-resolution display with a built-in GPS receiver and antenna. It uses Hybrid Control, so you can operate it by touchscreen, hard keys, a directional pad or a rotary knob. That flexibility matters on a bouncing deck, when wet fingers or gloves make touch input unreliable. NavPro units also include Wi-Fi and Bluetooth and integrate with NMEA 2000 accessories, so the display can become the hub of a larger electronics network. The line is also offered in larger 12-inch formats, and the Orion series adds a 10.4-inch hybrid-touch display that can be mounted in portrait or landscape orientation.

Choosing the Right Si-Tex Unit

• Screen size: Compact 5-inch SVS models suit small skiffs and tight consoles, while 9-inch and larger NavPro displays give more room for split-screen chart and sonar views.
• Chartplotter only or with sonar: Several models come in both versions, so you can add sounder capability now or later, depending on your fishing and navigation needs.
• Transducer pairing: Sonar performance depends heavily on the transducer, so match the transducer to your hull type, typical depths and cruising speed.
• Connectivity: If you plan to add AIS, radar or autopilot, look for NMEA 2000 support and wireless features.

Support Behind the Hardware

Si-Tex backs its products with a 2-year warranty and a Long Island-based service department, which is a real benefit for electronics that live in a salt-spray environment. Whether you fish inshore, run offshore or simply need reliable charting for coastal cruising, Si-Tex offers a straightforward path to dependable navigation and sonar.
