The Ultimate Buying Guide: Choosing Your Side Imaging Fish Finder
Finding the right side imaging fish finder can change how you fish forever. These gadgets let you see what’s happening on both sides of your boat, not just directly underneath. This guide helps you pick the best one for your needs.
Key Features to Look For
When shopping, you need to check several important features. These make a big difference in how well the finder works.
Screen Size and Resolution
- Screen Size: Bigger screens show more detail. For casual boaters, 5 inches might work. Serious anglers often prefer 7 inches or larger.
- Resolution: Higher resolution means clearer pictures. Look for screens that are bright and easy to read, even in bright sunlight.
Transducer Quality
The transducer sends and receives the sonar signals. This is the heart of the system.
- Frequency: Lower frequencies (like 200 kHz) give you deeper coverage. Higher frequencies (like 455 kHz or 800 kHz) provide sharper, more detailed side images, but don’t reach as far down.
- Beam Angle: Side imaging works best with wider beam angles. This lets you scan a larger area to the left and right of your boat.
GPS Capabilities
Good GPS helps you mark good fishing spots. Make sure the unit has built-in GPS or can connect easily to an external one. You want to save waypoints quickly.
Software and Interface
The software should be easy to use. You should be able to switch between down imaging, traditional sonar, and side imaging without getting lost in menus. A simple, clean interface improves your fishing time.
Important Materials and Durability
Your fish finder must handle the tough marine environment. Quality construction matters a lot.
Housing and Casing
Most good units use strong, waterproof plastic casings. Check the IP rating (Ingress Protection). An IPX7 rating means the unit can handle splashes and brief submersion, which is crucial on the water.
Cables and Connectors
Poor cables cause headaches. Look for thick, shielded cables that resist corrosion. Secure, locking connectors keep the transducer signal strong.
Factors That Improve or Reduce Quality
Not all side imaging units perform the same. A few factors really boost performance, while others cause frustration.
Improving Quality: Processing Power
Faster processors handle high-frequency sonar data better. This results in less lag when scrolling the screen and clearer, near-real-time images. Better processing power lets the unit interpret complex underwater structures accurately.
Reducing Quality: Interference
Electrical interference from your boat’s motor or other electronics can ruin your image. Units with good noise-filtering technology reduce this interference. If the image looks fuzzy or has lines, interference is likely reducing the quality.
User Experience and Use Cases
Think about how and where you fish. This guides your purchase.
Kayakers and Small Boats
If you use a kayak or small aluminum boat, you need a compact unit with low power draw. Portable battery packs are often necessary. Side imaging helps kayakers see structure near shorelines without constantly turning the boat.
Larger Bass Boats and Cruisers
These users benefit from large, networked displays. They often integrate side imaging with trolling motor mounts (like LiveScope or ActiveTarget) for incredible real-time views. They can run multiple transducers simultaneously.
A good side imaging fish finder gives you an advantage. It shows you exactly where the fish are hiding near logs, drop-offs, and weed lines.
10 Frequently Asked Questions (FAQ) About Side Imaging Fish Finders
Q: What is the main difference between Down Imaging and Side Imaging?
A: Down Imaging shows you what is directly beneath your boat. Side Imaging sweeps the water to the left and right, creating a panoramic view of structures beside you.
Q: Do I need a separate transducer for side imaging?
A: Often, yes. Many modern units use a single transducer that provides traditional sonar, down imaging, and side imaging views, but the side imaging signals come from specialized elements within that transducer.
Q: How deep can I effectively use side imaging?
A: While side imaging can reach very deep, the clarity drops off significantly past 150–200 feet. It works best in shallow to medium depths (under 100 feet) where detail is critical.
Q: Is side imaging better than traditional 2D sonar?
A: They serve different purposes. Traditional sonar is great for marking fish directly below and judging depth. Side imaging is superior for mapping the bottom contour and finding cover objects.
Q: What does “Chirp” technology do?
A: Chirp sends a continuous sweep of frequencies instead of a single ping. This provides much better target separation, making it easier to distinguish a fish from a bait ball.
Q: Can I use side imaging while the boat is stopped?
A: Yes, but it works best when the boat is moving slowly (1 to 5 mph). Moving allows the side beams to sweep across new areas, painting a complete picture of the sides.
Q: What is the ideal boat speed for clear side imaging?
A: Generally, speeds between 3 and 6 mph give the best results. If you move too fast, the images blur because the unit cannot process the data quickly enough for the distance covered.
Q: Does side imaging work in saltwater?
A: Yes, side imaging works well in saltwater. However, salt water scatters the signal more than fresh water, so you might see slightly less range or detail at extreme depths.
Q: How much power do these units use?
A: Larger, networked units with bright screens use more power. Always check the maximum draw (in Amps) to ensure your battery bank can handle it for a full day of fishing.
Q: Can I connect my side imaging unit to my smartphone?
A: Many newer models offer Wi-Fi or Bluetooth connectivity. This lets you view the sonar image on your phone or tablet, or update the unit’s software easily.
