Choosing Your Perfect Fishfinder GPS Combo: A Buyer’s Guide
Picking the right fishfinder GPS combo makes a huge difference on the water. This device helps you find fish and know exactly where you are. We break down what you need to look for before you buy.
Key Features to Look For
A great combo unit offers a mix of powerful searching tools and easy navigation. These features are crucial:
- Transducer Type and Frequency: The transducer sends signals into the water. Look for dual-beam or CHIRP technology. CHIRP sends a wide range of frequencies, giving you clearer images of fish and structure.
- Screen Size and Resolution: Bigger screens (7 inches and up) are easier to read in bright sunlight. High resolution means sharper images of what is below your boat.
- GPS Accuracy and Mapping: The GPS needs to lock on fast. Check if it comes with pre-loaded maps of your local waters. Advanced units let you save waypoints (favorite fishing spots) easily.
- Sonar Technology: Look for Down Imaging (shows what is directly underneath) and Side Imaging (shows what is to the sides). These tools help you cover more water.
Important Materials and Build Quality
Your fishfinder will face water, sun, and bumps. Quality construction keeps it working for years.
- Waterproofing Rating: Check the IP rating. An IPX7 rating means the unit can handle splashes and brief submersion. This is very important for marine electronics.
- Display Durability: The screen should use tough, scratch-resistant glass or plastic. Buttons and knobs must feel solid, not flimsy.
- Mounting Hardware: Good stainless steel or heavy-duty plastic mounts keep the unit stable, even when your boat speeds across choppy water. Cheap mounts often break first.
Factors That Improve or Reduce Quality
What makes one unit better than another? It usually comes down to processing power and software.
- Processor Speed: A fast processor handles complex sonar returns quickly. This means less lag when you change settings or scroll through maps. Slow processors frustrate users.
- Network Capability: Modern units often connect to other devices, like trolling motors or additional displays, using Ethernet or Wi-Fi. This expands the unit’s usefulness.
- Software Updates: Manufacturers who frequently update their software usually provide better performance and new features over time.
User Experience and Use Cases
How you plan to use the device guides your purchase. A small kayak angler needs something different than someone on a large bass boat.
- Ease of Use: Can you navigate the menus quickly? If the menus are too complex, you waste precious fishing time fiddling with settings. Touchscreen models are often faster to operate than button-only models.
- Power Consumption: If you fish all day without a big battery, look for units known for low power draw.
- Use Cases:
- Trolling: You need excellent Side Imaging to scan wide areas.
- Kayaking/Small Boats: Portability and a smaller screen might be better, but you still need strong sonar.
- Deep Water Fishing: You must have a transducer capable of reaching greater depths accurately.
10 Frequently Asked Questions (FAQ) About Fishfinder GPS Combos
Q: What is the main difference between a fishfinder and a GPS combo?
A: A fishfinder shows you what is under the boat (fish, depth, structure). The GPS tracks your location, lets you save spots, and helps you navigate back to them.
Q: Do I need CHIRP sonar?
A: CHIRP gives you much clearer, more detailed images than older fixed-frequency sonar. Most serious anglers recommend it for better target separation.
Q: How important is the screen size?
A: Screen size is very important for visibility. Larger screens let you view sonar and GPS maps side-by-side without squinting, especially when moving fast.
Q: Can I install a fishfinder GPS combo myself?
A: Yes, many combos are designed for DIY installation. You need to mount the display unit and securely place the transducer in the water.
Q: What does ‘Transducer Shoot-Thru-Hull’ mean?
A: This means the transducer is mounted inside the hull of a fiberglass boat, shooting the sonar signal through the bottom material. This protects it from damage.
Q: Will the GPS work if I am far from the shore?
A: Yes. GPS relies on satellites orbiting the Earth, not cell towers. It works almost anywhere on the water.
Q: How do I save a good fishing spot?
A: You use the GPS function to drop a “waypoint” marker on the screen right when you catch a fish or see great structure. You can then navigate back to that exact spot later.
Q: Is it okay if my unit gets wet?
A: Only if it has a good waterproofing rating (like IPX7). Always check the specific rating for the model you purchase.
Q: Are expensive units always better?
A: Not always, but higher prices usually mean better processors, brighter screens, and more advanced features like high-definition imaging.
Q: Can I use my existing trolling motor with a new fishfinder?
A: Sometimes. Many modern units connect through networking cables (like Ethernet) to share GPS data or control advanced trolling motors, but you must check compatibility first.
