Why Choose Built-In Dual Spectrum CHIRP?

Built-In Dual Spectrum CHIRP provides outstanding traditional sonar performance with excellent fish separation, bottom detail, and target clarity. It’s an ideal choice for anglers who already use Live Sonar, don’t need Side Imaging, or simply prefer a cleaner, more cost-effective electronics setup — while still benefiting from the Ulterra QUEST’s premium automation and GPS features.

Humminbird’s CHIRP technology uses a broad frequency range to deliver more detailed returns than traditional fixed-frequency sonar. The result is sharper fish arches, better bottom definition, and superior target separation at depth — especially in the deep water column where MEGA Side Imaging loses its advantage.

Why Built-In CHIRP Matters

• Superior fish target separation at depth — distinguish individual fish from each other and from structure where traditional sonar blurs the picture
• Clear fish arches — precise fish identification even in deep water columns
• Enhanced bottom detail — clearly define hard vs. soft bottom, rock transitions, and subtle structure changes
• Dual spectrum operation — wide beam for broad coverage, narrow beam for precise depth targeting
• Ideal pairing with Live Sonar — if you already run Humminbird MEGA Live or Garmin LiveScope, CHIRP complements Live Sonar without redundancy
• Lower overall system cost — CHIRP version is priced below the MEGA imaging version; savings can go toward your Humminbird display or battery system
• Protected transducer integrated into the lower unit — no exposed transducer to snag weeds or damage on launch
• Cleaner installation — motor and sonar share a single cable run to your Humminbird display

CHIRP vs. MEGA Side Imaging — Which Is Right for You?

If You Want…	Best Choice
Traditional sonar performance with superior depth detail	✅ Dual Spectrum CHIRP (this product)
Side Imaging of structure, timber, and flats	MEGA Down/Side Imaging — 60"
Maximum imaging detail and wide-area scanning	MEGA Down/Side Imaging — 60"
Lower overall system cost	✅ Dual Spectrum CHIRP (this product)
Already own Live Sonar (MEGA Live, LiveScope)	✅ Dual Spectrum CHIRP (this product)
Deep water vertical jigging and suspended fish	✅ Dual Spectrum CHIRP (this product)
Scanning brush piles, standing timber, offshore structure	MEGA Down/Side Imaging — 60"

Note: Dual Spectrum CHIRP requires a compatible Humminbird fish finder to display sonar. Contact us if you need help confirming compatibility with your existing electronics.

Why Choose the Ulterra QUEST Instead of the Instinct QUEST?

Both the Ulterra QUEST and the Riptide Instinct QUEST share Auto Stow & Deploy, Power Trim, and the QUEST brushless platform. The key differences are environment and sonar integration.

Feature	Ulterra QUEST	Riptide Instinct QUEST
Water type	Freshwater	Saltwater (Riptide-rated)
Integrated sonar	Dual Spectrum CHIRP or MEGA Down/Side Imaging	No integrated sonar
Auto Stow & Deploy	Yes	Yes
Power Trim	Yes	Yes
QUEST brushless motor	Yes	Yes
Spot-Lock with Jog	Yes	Yes
One-Boat Network	Yes	Yes
Best for	Tournament bass, walleye, muskie, deep structure, Great Lakes	Saltwater inshore, offshore center consoles, coastal fishing

If you fish freshwater and want integrated CHIRP sonar, the Ulterra QUEST is the correct motor. If you fish saltwater, see the Minn Kota Riptide Instinct QUEST lineup.

Frequently Asked Questions

What is the difference between Dual Spectrum CHIRP and MEGA Side Imaging?

Dual Spectrum CHIRP delivers superior 2D sonar target separation at depth — ideal for identifying suspended fish, deep structure, and bottom composition with precision. MEGA Side Imaging provides high-resolution, wide-area scanning to both sides of the boat, making it better for locating fish and structure quickly across a large area. If you primarily fish deep water vertically or already run Live Sonar, choose CHIRP. If you scan flats, timber, and offshore structure, see the MEGA Down/Side Imaging — 60" version.

Does this model include a foot pedal?

Yes. The Ulterra QUEST includes both a programmable heel-toe electric foot pedal and a wireless remote, giving you multiple control options from anywhere on the boat.

Can this motor run on both 24V and 36V?

Yes. The Ulterra QUEST 90/115 is a dual-voltage platform — 90 lbs on 24V, 115 lbs on 36V. For boats over 20 ft, we recommend 36V for maximum thrust and runtime.

What size boat is the 60" shaft best suited for?

The 60" shaft is ideal for 18–24 ft tournament bass boats, deep-V fishing boats, and walleye rigs with moderate-to-high bow profiles. It’s the most popular shaft length in the Ulterra QUEST lineup.

Is CHIRP a good choice if I already run Live Sonar?

Yes — this is one of the best use cases for the CHIRP version. If you already run Humminbird MEGA Live or a similar Live Sonar system, Dual Spectrum CHIRP complements it without redundancy.

Is this motor saltwater-rated?

No. The Ulterra QUEST is a freshwater motor. For saltwater use, see the Minn Kota Riptide Instinct QUEST lineup.

What quick-release bracket fits this motor?

The Minn Kota RTA-62 Quick Release Bracket is compatible with the Ulterra QUEST.
