• Application: Commercial river fishing, deep sea fishing, and fishery research

Why Choose This Commercial Fish Finder Device?

1. Choose Your Power – From 600W to 3000W

Not every fishing operation needs the same power. This fish finder device is available in multiple output power configurations:

• 600W-1000W – ideal for coastal, inshore, and river fishing
• 1500W – for offshore and deeper continental shelf fishing
• 3000W – for deep sea, longline, and commercial trawling operations

Tell us your typical fishing depth and target species – we'll recommend the right power option.

2. Daylight-Viewable TFT Display with Night Mode

The TFT LCD color display is specifically engineered for marine use:

• Daylight viewing – high brightness, anti-glare for direct sun conditions
• Dimmable backlight – preserves night vision during early morning or late evening fishing
• 8 or 12 color bar – different colors represent different echo strengths, making it easy to distinguish bottom hardness, vegetation, and fish schools at a glance

3. Dual-Frequency Versatility (50/200 kHz)

Switch between frequencies based on your needs:

• 50 kHz – wide beam angle, broader coverage for searching large areas, better depth penetration
• 200 kHz – narrow beam, higher detail for bottom structure and target separation

4. Flexible Installation – Table or Flush Mount

Choose the mounting style that fits your helm:

• Table mounting – simple bracket installation, easy to adjust or remove
• Flush mounting – clean, professional look, recessed into dash or console

5. Advanced Functions for Commercial Use

• Zoom function – magnify specific depth ranges to see bottom detail or fish holding near structure
• Relay display – remote viewing capability (for second station or crew monitoring)
• Units selectable – display depth in meters (M) or fathoms (FM) as preferred

ISO9000 Quality Assurance – From Raw Material to Shipment

SAIYANG follows ISO9000 standards throughout the manufacturing process:

• Raw material inspection before production
• In-process quality checks during assembly

Frequently Asked Questions

Which power option is right for my fishing?

As a guideline: 600W-1000W for coastal and river (to ~400m), 1500W for offshore to ~1000m, 3000W for deep sea beyond 1000m. Contact us with your target depth and typical bottom type – we'll provide a specific recommendation.

Can I use this for both fresh and saltwater?

Yes. This commercial fish finder device is built for both freshwater and saltwater environments. Select the appropriate transducer for your application (contact us for saltwater-specific options).

What's the difference between table mount and flush mount?

Table mount uses a bracket that sits on top of a surface – easy to install and remove. Flush mount cuts the display into the dashboard for a seamless, permanent installation. Choose based on your helm layout and preference.

How does the color bar help me?

The 8 or 12 color bar assigns different colors to different echo return strengths. Typically: red/orange = strong return (hard bottom, large fish), blue/green = weaker return (soft bottom, smaller targets). This allows immediate visual interpretation without analyzing numbers.

Do you offer OEM or custom branding?

Yes. As a manufacturer with 18+ years of experience, we provide OEM/ODM services, custom labeling, and specific power/transducer configurations for fleet operators and distributors.
