THKFISH Fishing Tackle Box 3700S Tackle Tray - Floating Waterproof

In this review of the THKFISH Fishing Tackle Box 3700S, the bottom line is simple: it is a compact, durable organizer best for anglers who want a lightweight, floating solution to keep small lures and terminal tackle tidy and protected. The most convincing reason to buy is the combination of a floating, sealed lid and an array of removable dividers that let you customize storage for different-sized baits, making it a practical companion for boat, kayak or shore fishing.

Key Features

• Floating design: The box floats if dropped in water, so loose gear can be recovered quickly and kept from soaking.
• Waterproof lid with gasket: A blue silicone gasket and three cam-action latches form a tight seal that helps keep contents dry from splashes.
• Thick, tough construction: Made from high toughness PE material with a thickened frame and one-piece box to resist cracking and long-term wear.
• Transparent lid and sun-proof body: The translucent lid makes contents easy to identify while the blue-black body reduces sun exposure to help extend bait life.
• Adjustable dividers: Fifteen removable dividers provide flexible compartment layouts so anglers can organize oversize and small lures.

Who It's For

The 3700S is ideal for anglers who need a portable, lightweight tackle solution for small to medium baits and terminal tackle while fishing from a boat, kayak or shore. Its floating capability and secure latches make it especially useful when working near water where drops and splashes are likely.

It may be less suitable for anglers who require very large multi-layer storage or someone looking for a rigid, heavy-duty desktop chest to hold dozens of large hard baits; those users should consider larger multi-tier systems. Also, while the seal is good for splashes, anyone requiring guaranteed submersion-proof storage for electronics or sensitive items should use a dedicated dry box.

Pros & Cons

Pros

• Floats on water, reducing the risk of losing a box overboard.
• Sturdy PE construction and strong cam-action latches for reliable everyday use.
• Fifteen removable dividers allow flexible, personalized layouts.
• Translucent lid speeds identification while the sun-proof body helps protect baits.

Cons

• Some customers report mixed experiences about full waterproof performance, so it is best treated as splash-resistant rather than guaranteed submersion-proof.
