Lowrance PDRT-WBL Shoot Thru-Hull

Unlock Reliable Depth Readings Without Drilling Holes

Imagine gliding across calm waters or navigating choppy lakes without compromising your boat's sleek lines or structural integrity. The PDRT-WBL transducer changes the game for anglers and boaters who prioritize clean installations and consistent performance. Mounted securely inside the hull, this innovative sensor sends sonar signals right through fiberglass or aluminum, delivering precise depth information and water temperature data straight to your display. Perfect for those upgrading their setup on bass boats, pontoons, or any vessel where external mounts just won't cut it.

At 200 kHz with a generous 20-degree beam angle, it paints a wide picture of the underwater world—ideal for spotting structure, baitfish schools, and contours in waters up to moderate depths. No more wrestling with thru-hull fittings or worrying about prop strike damage. Just pure, hassle-free connectivity via its 20-foot cable with the reliable blue connector.

Key Features That Stand Out on the Water

• Shoot-Thru-Hull Design: Bonds seamlessly to the inside of your hull, transmitting signals without penetration—preserving your boat's warranty and aesthetics.
• Wide 20-Degree Beam: Covers more bottom area for quicker target acquisition, especially in shallower bays or rivers where fish hug the edges.
• Integrated Remote Temperature Sensor: Tracks surface water temps accurately, helping you pinpoint thermoclines or prime feeding zones as conditions shift.
• Pod-Style Build: Compact and low-profile, it fits snugly in tight spaces like bilge areas or under decks.
• Durable Construction: Built to withstand vibration, moisture, and the rigors of repeated launches—ensuring years of dependable service.

Seamless Installation for DIY Enthusiasts

Getting this transducer up and running doesn't require a marine yard visit. Start by selecting a flat, solid section of your hull—away from strakes, engines, or aerated water zones. Clean the surface thoroughly, apply a marine-grade epoxy or adhesive, and press the pod firmly in place. Let it cure fully before testing. The 20-foot cable gives you flexibility for routing to your unit, and the blue connector ensures a plug-and-play fit with compatible Lowrance models.

Pro tip: For optimal signal strength, aim for hull thicknesses under 1 inch and avoid heavily cored materials. Test in shallow water first to fine-tune your gain and sensitivity settings. Many users report crystal-clear readings right out of the gate, rivaling traditional external pods.

Performance Tailored to Real-World Fishing Scenarios

In shallow freshwater haunts like reservoirs or coastal flats, the wide beam excels at revealing subtle drop-offs and weedlines that hold crappie or walleye. Switch to saltwater pursuits, and it holds its own tracking bottom fish along structure without the clutter of narrower beams. Pair it with your chartplotter for split-screen views of sonar and temp overlays, giving you the edge during dawn patrols or twilight bites.

Unlike some budget alternatives, this unit resists air bubbles and foam interference common in rough conditions, maintaining lock on the bottom when others falter. Anglers praise its sensitivity to small jigs and minnow imitations bouncing along the substrate.

Long-Term Reliability and Care Essentials

To keep performance peaking, inspect the pod periodically for hull delamination or cable wear. A quick freshwater rinse after brackish use prevents buildup. Over time, this transducer proves its worth by minimizing downtime and maximizing screen time focused on the hunt.
