Transform Your Fish Finder into a Go-Anywhere Powerhouse
Picture this: you're chasing bass on a secluded pond, probing depths from a kayak, or setting up for ice fishing far from shore. With the right portable setup, your favorite Humminbird unit becomes your ultimate fishing companion, untethered from boat power. The PTC U2 portable conversion kit turns fixed-mount HELIX and other series models into lightweight, battery-powered systems ready for adventure.
This soft-sided carry case isn't just a bag—it's a complete mobility solution designed by anglers for anglers. Its thoughtful compartments keep everything organized, protected, and instantly deployable, so you spend more time on the water and less fumbling with gear.
Everything You Need for Instant Portability
-
Custom-Fit Soft Bag: Durable, padded design with a sturdy carry handle for easy transport over rough terrain or tight kayak hatches.
-
Dedicated Storage: Separate spots for your transducer, control head, rechargeable 12V battery, smart charger, cables, and accessories—no more tangled messes.
-
Quick-Convert Hardware: Includes gimbal mounts tailored for HELIX 5 and HELIX 7 series, plus universal fittings for seamless swap from boat to portable mode.
-
Power On-Demand: Built-in battery delivers reliable runtime for full-day sessions, with the smart charger preventing overcharge and extending lifespan.
Engineered for real-world fishing, this kit withstands splashes, bumps, and the elements while staying compact enough to stow in your vehicle trunk or tackle box.
Perfect for Kayak, Ice, Shore, and Small Boat Fishing
Kayak anglers love how the lightweight setup mounts securely without drilling or permanent mods. Ice fishermen appreciate the transducer compartment's easy access for tip-up or VIVID puck deployment. From riverbanks to jon boats, it unlocks sonar intel wherever fish hide.
Setup takes minutes: slide your unit into the gimbal, connect the battery, drop the transducer, and you're scanning structure with CHIRP clarity or Side Imaging precision. Pro tip: Pair it with a suction-cup transducer mount for versatile positioning on smooth surfaces.
Broad Compatibility Across Humminbird Lineup
Works flawlessly with HELIX 7 and HELIX 5 series for high-res detail, plus all 100, 300, 500, 600, and 700 series units. Whether you're running a compact 5-inch screen or a feature-packed 7-incher, this kit adapts to your setup without custom tweaks.
Verify your model's gimbal compatibility for the smoothest install—most users report plug-and-play ease, preserving your unit's warranty while adding portability.
Maximize Longevity and Performance
Keep your portable rig humming by rinsing with fresh water after saltwater use, drying compartments fully, and storing the battery at half-charge in cool conditions. The smart charger handles the rest, optimizing cycles to avoid deep discharges that shorten life.
For extended trips, carry a spare battery or solar maintainer. Regularly inspect gimbal mounts and zippers for wear—these small habits ensure seasons of reliable service.
