Your Guide to Choosing the Best Side Image Fish Finder
Finding the right side image fish finder can change how you fish. These tools let you see what is under the water to your left and right. This guide helps you pick the perfect model for your needs.
Key Features to Look For
When shopping, keep these important features in mind. They make a big difference in how well the finder works.
Transducer Type and Beam Angle
- Transducer: This is the part that sends and receives signals underwater. Look for models with high-quality transducers.
- Beam Angle: Side imaging works best with wider beams. Wider angles show you more area to the sides. A wider view is usually better for covering ground quickly.
Resolution and Display Quality
- Screen Size: Bigger screens are easier to read, especially when moving fast.
- Pixel Resolution: Higher resolution means clearer pictures. Clear pictures help you spot small details, like thin lines of baitfish or submerged logs.
GPS and Mapping Capabilities
- Built-in GPS: Good GPS lets you mark hot spots. You can save the exact location of a great fishing spot.
- Mapping: Some units come with pre-loaded maps. Others allow you to download detailed charts of lakes and rivers.
Waterproof Rating
Your finder will get wet. Make sure it has a good waterproof rating (like IPX7). This keeps the electronics safe from rain and spray.
Important Materials and Build Quality
The materials used affect how long your fish finder lasts. Durable construction is essential for time spent on the water.
Transducer Material
The outside casing of the transducer should be strong. Plastic is common, but high-quality, impact-resistant plastic is best. Some high-end models use bronze, which lasts a very long time.
Screen Durability
The screen needs protection. Look for scratch-resistant glass or tough, glare-free plastic screens. Sunlight reflection can make the screen hard to see.
Factors That Improve or Reduce Quality
What makes one side imaging unit better than another? It often comes down to processing power and software.
Improving Factors (Better Quality)
- Software Updates: Manufacturers who regularly update their software improve performance and add features.
- Chirp Technology: Chirp sonar sends a range of frequencies, which gives much clearer images than older, single-frequency sonar. This greatly improves target separation.
- Processing Speed: Faster processors update the image quickly. This is important when you drive your boat fast.
Reducing Factors (Lower Quality)
- Interference: Poorly shielded electronics can pick up interference from your boat’s motor or other electronics. This creates “noise” on the screen.
- Shallow Water Performance: If the unit struggles to give clear readings in shallow water, its overall usefulness is reduced.
User Experience and Use Cases
A great fish finder should be easy to use, even for beginners.
Ease of Use
Test the menu system if possible. Simple, intuitive menus let you change settings fast. You do not want to spend lots of time fiddling with buttons when the fish are biting.
Ideal Use Cases
- Structure Scanning: Side imaging excels at finding submerged structure like rock piles, old roadbeds, and sunken timber off to the sides of your boat.
- Bait Ball Detection: It helps you see schools of baitfish holding underneath your boat, which tells you where the bigger predators might be hiding.
- Kayak Fishing: Smaller, battery-efficient units are perfect for anglers using kayaks or smaller boats where space is limited.
Frequently Asked Questions (FAQ)
Q: How much better is side image than traditional down-looking sonar?
A: Side image scans wide areas to the left and right of your boat. Traditional sonar only looks straight down. Side image helps you cover much more water horizontally, finding structure faster.
Q: Do I need a special transducer for side imaging?
A: Yes, you do. Side imaging requires a specialized transducer designed to send signals out sideways, not just down.
Q: Can I use a side image finder in very clear water?
A: Yes, clear water often shows the best results with side imaging. The sharp contrast between the water and the bottom structure appears very clear on the screen.
Q: Will side imaging work well in muddy water?
A: Side imaging struggles more in muddy or silty water than traditional down-looking sonar. Murky water scatters the side signals more easily.
Q: What is “Chirp” technology in fish finders?
A: Chirp sends multiple frequencies at once. This sends clearer signals back to the unit. Clearer signals mean you see fish and structure better separated from each other.
Q: Is GPS mapping necessary for side imaging?
A: While not strictly necessary just to *see* the bottom, GPS is highly recommended. It lets you save the exact coordinates of every good spot you find using the side view.
Q: How do I mount the transducer correctly?
A: The transducer must be mounted so the bottom of the unit sits just below the hull. It must point straight out to the side and remain in clean, undisturbed water when the boat moves.
Q: What is the typical price range for a good unit?
A: Entry-level side imaging units start around $300 to $500. High-end, multi-function displays with advanced mapping can cost well over $2,000.
Q: How much battery power do these units use?
A: Larger screens and high-powered units use more power. Always check the manufacturer’s listed amperage draw to ensure your battery lasts a full day of fishing.
Q: Do I need special training to read the side images?
A: Some practice is needed, but most modern units use color coding to help. Hard bottoms appear dark, while suspended objects or soft bottoms appear lighter. Most manufacturers provide excellent tutorials online.
