Discover Superior Underwater Detection with the Furuno CA200B-12H

Upgrade your marine electronics setup with a transducer engineered for precision and durability in demanding saltwater environments. This rubber-coated powerhouse delivers exceptional clarity for spotting fish, structure, and bottom contours at impressive depths. Ideal for serious anglers and commercial operators who demand reliable performance without the hassle of frequent replacements.

Crafted from robust materials that withstand constant submersion and hull vibrations, it mounts seamlessly in a tank for protected, thru-hull-style operation. The narrow beam focuses energy for pinpoint accuracy, making it a go-to choice for targeting species in deeper waters where broad coverage falls short.

Expanded Features for Peak Performance

• High-Power Output: 5kW of raw power punches through thermoclines and murky water, revealing details others miss.
• Precise Frequency: Operating at 200kHz, it balances resolution and range perfectly for mid-to-deep water scanning.
• Narrow Beam Design: A tight 4-degree beam angle concentrates sonar energy, offering crystal-clear images of tightly schooled fish or wrecks.
• Durable Construction: Rubber coating shields against impacts, corrosion, and marine growth, ensuring longevity in rough conditions.
• Practical Weight and Cable: At 11 pounds, it's manageable for most installations, paired with a 15-meter cable for flexible routing—no plug means customizable connectivity to your sounder.

Unlike plastic or bronze alternatives, the rubber coat provides superior shock absorption, reducing noise from boat motion and delivering cleaner returns on your display.

Effortless Tank Mounting Installation

Setting up this transducer is straightforward for DIY boat owners or pros. Position it in a dedicated tank below the waterline for optimal signal transmission. Drill a precise hole matching the transducer's footprint, secure with marine sealant, and route the cable through existing conduits to your Furuno black box or multifunction display.

1. Clean and fair the tank surface for a flush fit.
2. Apply polyurethane sealant around the mounting flange.
3. Torque bolts evenly to prevent leaks.
4. Test alignment using your sounder's calibration tools—aim for a dead-ahead orientation to maximize beam effectiveness.

Pro tip: In high-speed applications, angle it slightly forward (2-5 degrees) to compensate for hull deadrise and maintain bottom lock at planing speeds.

Real-World Applications and Performance Edge

Fishermen chasing tuna or swordfish in offshore canyons swear by its ability to separate targets from bait balls at 1,000+ feet. Charter captains appreciate the consistent bottom tracking over reefs and ledges, while surveyors value the detailed contour mapping for navigation charts.

In choppy seas, the rubber coating minimizes air entrainment, keeping your screen free of clutter. Pair it with high-end Furuno processors for A-Scope views that highlight fish size and movement direction, giving you the intel to set lines right.

"Switched to this from a standard thru-hull—night and day difference in deep-water resolution. Worth every bit of install time."

Long-Term Maintenance for Reliability

Keep it performing like new with simple routines. After every trip, rinse with fresh water to flush salt. Inspect the rubber coat annually for cracks—touch up with marine-grade silicone if needed. Avoid antifouling paints on the face to prevent signal attenuation. Store the boat with the transducer de-watered during layups to dodge freezing damage.

Monitor cable integrity during haul-outs; splice and heat-shrink any frays for uninterrupted service.
