Fishfinders & Combinations

Fishfinders & combo units: revealing the secrets of the seabed

Whether you're a recreational or professional fisherman, understanding what's happening beneath your hull is crucial. Skysat, with its extensive experience in competitive marine electronics, guides you in choosing and integrating your fishfinders and fishfinder combos. Discover here the key technologies and essential criteria for accurate and reliable detection.

Choosing the right fish finder for your fishing

The wide variety of fishfinders and fishfinder combos can make choosing the right one complex. Key factors include frequency (which affects depth and resolution), power (for increased range), and imaging technologies (for more intuitive bottom interpretation). A fishfinder suited to your fishing style and cruising areas will maximize your chances of success.

• CHIRP sonar: Frequency scanning technology for better target separation and a clearer image.
• Traditional fish finder (50/200 kHz): Versatile for deep-water and coastal fishing. Choose the frequency according to the depth and bottom type.
• DownVision/SideVision Sounder: 2D imaging of underwater and lateral structures for efficient prospecting. Requires moderate navigation speed for optimal image quality.
• 3D sonar: Three-dimensional representation of the seabed for an intuitive understanding of the environment. Higher power consumption.

integrating the handset into your network

A combined unit integrates the functions of a fishfinder and GPS plotter, offering space savings and data synchronization. Integration into an NMEA 2000 or SeaTalk NG network allows information to be shared with other instruments (autopilot, VHF radio, etc.) for safer and more efficient navigation. Verify protocol compatibility for seamless integration.

• NMEA 2000: Standard protocol for sharing data between instruments. Easy cabling and network expansion.
• SeaTalk NG: Raymarine proprietary protocol, compatible with NMEA 2000 via an adapter. Optimized integration with Raymarine products.
• Mapping: Choose a map compatible with your device (Navionics, C-MAP). Regular map updates are essential.
• Touchscreen: Facilitates menu navigation and function use. Sensitivity varies depending on the model and weather conditions.

💡 Skysat's advice

Before investing, simulate the use of the fishfinder/combinet in a store or at a boat show. Screen clarity, menu ergonomics, and ease of data interpretation are essential criteria for optimal use at sea.
