The Ultimate Buying Guide for Your New Fish Finder
Ready to catch more fish? A fish locator, or fish finder, is a crucial tool. It helps you see what lies beneath the water’s surface. This guide will help you pick the best one for your needs.
Key Features to Look For
When shopping, look closely at these important parts. They make a big difference in how well the finder works.
Display Quality and Size
- Screen Resolution: A clearer screen shows you better details of the bottom and the fish. Look for high-pixel screens.
- Screen Size: Bigger screens are easier to read, especially when you are moving fast or far away. Small boats might need smaller screens.
Sonar Technology
Sonar sends sound waves into the water. The echo tells the finder what is down there.
- Frequency: Lower frequencies (like 50 kHz) see deeper. Higher frequencies (like 200 kHz) give clearer, more detailed pictures close to the boat. Dual-beam or multi-beam sonar is often best.
- CHIRP Technology: CHIRP sends a range of frequencies. This gives much better target separation—you can easily tell a bait ball from a big fish!
GPS and Mapping
Good fish finders include GPS. This lets you mark spots where you found fish.
- Waypoint Storage: Make sure it stores many waypoints. This lets you return to secret spots later.
- Base Maps: Some units come with basic maps already loaded. Upgrade options can show detailed bathymetric charts (depth maps).
Important Materials and Durability
Your fish finder needs to survive water, sun, and bumps. The materials matter.
- Transducer Material: The part that goes in the water (the transducer) is usually tough plastic or bronze. Bronze lasts longer but costs more.
- Housing: The main unit should have a strong, waterproof casing. Look for high IP ratings (like IP67) which mean it resists water splashes and dust well.
Factors That Improve or Reduce Quality
What makes one fish finder better than another? It often comes down to power and processing.
Quality Boosters
- Higher Power Output (Wattage): More power lets the sonar reach deeper and gives a stronger signal return.
- Advanced Software: Modern processors handle complex images quickly. This means faster updates on your screen.
- Down Imaging/Side Imaging: These features give near-photographic views below and to the sides of your boat. They greatly improve target identification.
Quality Reducers (Things to watch out for)
- Poor Screen Glare: If you cannot see the screen in bright sunlight, the unit is hard to use. Check reviews for daytime visibility.
- Slow Refresh Rate: If the screen takes too long to update, you miss fish swimming by quickly.
User Experience and Use Cases
How you plan to use the finder changes what you should buy.
Kayaks and Small Boats
These users need portable, smaller units. Battery life is very important since you might be far from shore. Transom-mount or shoot-thru-hull transducers are common choices.
Larger Boats and Deep Sea Fishing
These require powerful units with advanced networking capabilities. They often need high-powered CHIRP and detailed mapping features to cover large areas effectively.
Ease of Use
Think about how easy the menus are. Some advanced units can be complex for beginners. If you are new, choose a model known for its simple interface. Most modern units offer automatic settings that adjust sonar power for you.
10 Frequently Asked Questions (FAQ) About Fish Locators
Q: Do I need a transducer with my fish finder?
A: Yes, absolutely. The transducer sends and receives the sonar signals. Most fish finders come with one, but sometimes you buy a more powerful one separately.
Q: What is the difference between Down Imaging and traditional sonar?
A: Traditional sonar shows fish and the bottom as arches or lines. Down Imaging shows a picture-like view directly beneath your boat, making objects look more real.
Q: Can I use a fish finder in freshwater and saltwater?
A: Most modern units work in both. However, saltwater often requires a lower frequency setting for better deep-water penetration.
Q: How important is GPS on a fish finder?
A: GPS is very important. It lets you save the exact location of fish, underwater structures, and safe routes.
Q: What is CHIRP and why should I want it?
A: CHIRP sends many sonar frequencies at once. This gives you much clearer images and helps you separate individual fish from bait schools.
Q: How is the unit powered?
A: Most units use a 12-volt battery, like a small marine battery. Battery life varies greatly depending on screen brightness and how often you use features like GPS.
Q: Will a fish finder work if I mount it inside the hull of my fiberglass boat?
A: Yes, this is called “shoot-thru-hull” mounting. It works well with fiberglass, but the material must not have air bubbles or thick layers that block the signal.
Q: Are expensive fish finders always better?
A: Not always, but more expensive models usually offer better screen resolution, deeper range, and advanced features like Side Imaging. For casual fishing, a mid-range unit is often perfect.
Q: How do I install the transducer?
A: For most trolling motors or transoms, the transducer must be fully submerged in the water when the boat is moving, but not so deep that it causes too much drag.
Q: What is the ideal screen size for a beginner?
A: A screen between 5 and 7 inches is usually ideal for beginners. It offers a good balance between visibility and portability.
