Best Fish Finder for Bennington Boats | Catch More & Navigate Shallow Lakes Like a Pro
You ease your Bennington into a quiet cove, cut the engine, and wonder—are the fish hiding just beneath you, or are you wasting your time in an empty spot?
Here’s the thing about fishing from a Bennington pontoon boat. These boats are incredible platforms for angling. They’re stable, spacious, and can slip into water that’s barely knee-deep. But without a good fish finder, you’re basically guessing. The right sonar unit turns your pontoon into a fish-finding machine, showing you exactly where the bass are hiding, how deep the water is, and what the bottom looks like—all without drilling a dozen holes in your beautiful boat.
TL;DR
The best fish finders for Bennington boats balance screen size, sonar clarity, and easy mounting. Garmin Striker Vivid 7sv leads for casual anglers with its 7-inch vivid display and ClearVü scanning. Humminbird Helix 7 MEGA DI offers pro-level imaging for serious fishermen. Lowrance HDS LIVE 9 is the premium choice with live sonar and networking. For simple depth and temp, the Garmin Striker 4 is a budget winner. Mount the display with a RAM mount and place the transducer on the transom, not behind a pontoon log.
Key Takeaways
- Screen size matters—5 to 7 inches is the sweet spot for pontoon consoles.
- CHIRP sonar cuts through murky water better than traditional sonar.
- Side imaging helps you scan wide areas—perfect for finding structure before you commit to a cove.
- Transducer placement is everything. Mount it on the transom, away from turbulent water behind the logs.
- GPS and mapping let you mark hotspots and return to them trip after trip.
Why a Fish Finder Belongs on Your Bennington
Bennington builds some of the most stable recreational boats on the market. That stability isn’t just good for family cruising—it’s a huge advantage for fishing . You can stand, cast, and fight a fish without feeling like you’re going overboard. But even the best lake cruising boat won’t help you find fish if you don’t know where they’re hiding.
A good fish finder does three things for you:
- Shows you structure—submerged logs, weed beds, drop-offs where fish love to hang out
- Reads depth—so you don’t run aground in shallow coves
- Tracks water temperature—fish move with temp changes, and knowing that gives you an edge
Ever spent an hour casting at nothing while the fish were ten feet to your left the whole time? A fish finder fixes that.
“Fish finders take a lot of the guesswork out of fishing by allowing you to easily determine fish and school size and location, water temperature, wave speeds, and bait depth.” — Bennington Marine
Rhetorical question: Would you drive blindfolded? Then why fish without seeing what’s under your boat?
Understanding Sonar Types for Pontoon Fishing
Before we get into specific models, let’s break down the tech. Pontoon boats are different from bass boats. You’re usually fishing in shallower water (5 to 30 feet), and you need sonar that performs at low speeds .
Traditional Sonar (2D)
The basic stuff. Sends a cone-shaped beam straight down. Shows fish as arches. Works fine, but you don’t see much detail.
CHIRP Sonar
Think of this as traditional sonar on steroids. It sends a range of frequencies instead of just one. The result? Cleaner images, better target separation, and less clutter. For murky lake water, CHIRP is a game-changer.
Down Imaging
This gives you a picture-like view of what’s directly under the boat. You can see individual rocks, logs, and even the shape of weed beds.
Side Imaging
The big one for pontoons. Side imaging scans to the left and right of your boat—sometimes 100 feet or more in each direction. You can spot structure before you even drive over it. Perfect for exploring new coves without risking your lower unit.
Rhetorical question: Have you ever motored into a beautiful cove only to realize it’s full of hidden stumps? Side imaging shows you those hazards before they find you.

Mounting Your Fish Finder on a Bennington
Here’s where Bennington owners run into trouble. Your pontoon doesn’t have a big fiberglass console like a bass boat. You need a smart mounting solution.
Display Mounting Options
RAM Mounts are the gold standard. They clamp onto rails, stick to flat surfaces with suction cups, or bolt through existing holes. One owner used a Scosche magnetic mount to attach their Striker 4 to the dash—no drilling required .
Pro tip: Use a quick-release mount so you can remove the head unit when the boat is parked. Theft and sun damage are real problems.
Factory locations: Some Bennington models come with a pre-wired spot for a Striker 4 right in the middle of the dash. Check if yours has this before drilling anything .
Rhetorical question: Ever drilled a hole in the wrong spot on a brand new boat? Measure twice, or better yet, use a clamp mount first.
Transducer Placement
This is the most critical part. The transducer sends out the sonar signal. If it’s in the wrong spot, you get noise, lost readings, or nothing at all.
The right way: Mount the transducer on the transom (back of the boat), positioned so it sits just below the bottom of the motor’s lower unit .
The wrong way: Mounting it directly behind a pontoon log. The turbulent water flow creates “noise” on your screen, making it impossible to get a clear reading at speed .
One owner solved their depth-reading issues by lowering their transducer just two inches. After that, they held depth readings at 28 mph without losing signal .
Safety reminder: Always wear life jackets and follow local boating laws when operating any vessel. A fish finder helps you navigate safely, but it doesn’t replace basic seamanship.
Screen Size vs. Readability at Distance
This chart shows why bigger screens matter on a pontoon, where you might be standing several feet from the helm while fishing.
Look at the jump from 5 to 7 inches. That extra two inches of screen doubles the distance you can read it from—huge when you’re fishing from the bow.
Wiring and Power Tips
Most Bennington pontoons have spare accessory switches on the helm. Use one. Connecting to a dead switch is much cleaner than wiring directly to the battery.
Step-by-step wiring:
- Find an unused accessory switch on your helm panel
- Run the fish finder’s power wire to that switch
- Use a wire tap or butt connector for a secure connection
- Ground to the common ground bus bar (usually near the fuse panel)
Pro tip: If you’re not comfortable with wiring, any marine electronics shop can do this for under $100. It’s worth it to avoid electrical gremlins later.
One owner shared: “I connected the power to the accessory switch using a wire tap. Works great” .
Rhetorical question: Have you ever dealt with a loose wire connection that cuts out every time you hit a wake? Take the extra five minutes to do it right the first time.
Integrating with Your Bennington’s Systems
Modern Benningtons with Advanced Digital Helm Displays can integrate directly with fish finders. If you have a Simrad or Garmin unit, you can often display engine data—RPM, fuel flow, trim—right on the fish finder screen .
One owner asked about connecting their fish finder to their Yamaha outboard for engine data. The answer? Yes, with a NMEA 2000 network gateway, you can see everything on one screen .
That’s the dream setup: sonar, GPS, and engine gauges all on one beautiful display.
Maintenance for Long Life
Pontoon boats live outside, and electronics take a beating. Follow these tips to keep your fish finder working for years:
- Wipe the screen after every trip with a microfiber cloth. Hard water spots etch the display over time .
- Never use household glass cleaners—they strip the anti-glare coating.
- Use dielectric grease on cable connections to prevent corrosion .
- Remove the head unit when the boat is stored, or use a protective cover. UV rays destroy LCD screens.
- Check transducer screws at the start of each season. Vibration loosens them.
Rhetorical question: Would you leave your phone in the sun and rain every day? Then why leave your fish finder exposed?
