Your favorite crankbaits and jigs are only as good as the box that keeps them dry, rust-free, and organized. A poorly sealed 3700 tray can leave your terminal tackle corroded after a single wet trip, turning an expensive collection into scrap. The right box doesn’t just store gear—it protects your investment with a watertight seal, durable latches, and smart dividers that keep every hook and swivel in its place.
I’m Rikta — the co-founder and writer behind FitlyFast. I’ve spent dozens of hours analyzing seal integrity, plastic thickness, divider adjustability, and rust-prevention technologies across the most popular 3700 tackle trays to pin down which boxes truly deliver on their promises.
Whether you’re an ice angler, kayak fisherman, or weekend bass chaser, choosing a 3700 tackle box means balancing waterproofing, build density, and compartment flexibility against your specific loadout and storage conditions.
How To Choose The Best 3700 Tackle Box
Selecting a 3700 tray goes beyond just matching dimensions. Focus on the seal quality, divider system, and material thickness, as these directly determine how well your lures survive the ride.
Seal and Waterproofing
Look for a continuous O-ring gasket (like Dri-Loc or a full 360° silicone seal) rather than a single compression strip. Cam-action latches that provide even pressure across the lid edge are critical—bargain boxes with a single center latch often let moisture seep in at the corners. Desiccant cartridges are a bonus for humid climates.
Divider System and Usable Depth
Pre-cut, vented dividers let you tailor compartment sizes for everything from bulkier spinnerbaits to tiny ice jigs. Dividers that lock into place against the bottom prevent hooks from migrating between cells. A depth of at least 1.8 inches is ideal for storing 3-inch crankbaits upright, while 2-inch profiles handle larger saltwater lures without crushing trebles.
Material and Build Toughness
Polypropylene (PP) boxes that measure 2 to 3 mm in wall thickness resist cracking when dropped on a boat deck or packed tightly in a bag. Avoid thin, brittle plastics—they flex under weight and can pop open on impact. Some premium trays add a rust-inhibitor infused base, which actively prevents corrosion inside the box.

In‑Depth Reviews
1. KastKing Karryall Fishing Tackle Bag with 4x 3700 Trays
This is the complete solution for anglers who want a single carry-all that includes four 3700 trays. The bag’s main compartment is wide-mouth with a double-loop zipper, giving you fast access to the trays without wrestling with a narrow opening. The 600D Oxford outer layer with a hydrophobic coating sheds rain and splashes, while the inner PVC layer adds a second moisture barrier—critical for kayak or boat trips where gear gets sprayed.
The 13 internal and external pockets are intelligently placed: a large back mesh pocket for quick-grab items, a front dual-zippered section, a hidden water bottle pocket with a retention strap, and integrated pliers and scale holsters on the sides. The MOLLE panel on the front lets you clip on accessory pouches or a net. The included 3700 trays have removable dividers, so you can adjust compartments for everything from bulky swimbaits to tiny split shots.
Rubber non-slip foot pads keep the bag planted on wet boat decks or muddy banks. The padded shoulder strap and reinforced web handle distribute weight evenly, making it comfortable even when fully loaded with 4 trays plus tools. For the angler who needs a ready-to-go system, this bundle saves the hassle of buying trays and a bag separately.
Why it’s great
- Trays are included—no extra purchase needed
- Water-resistant 600D Oxford with inner PVC layer
- 13 pockets including pliers and scale holsters
Good to know
- Bag weighs about 2.3 lbs empty before adding trays
- Mesh pockets on the lid can invert when fully unzipped
2. Plano EDGE 3700 Premium Tackle Utility Box
Plano’s EDGE 3700 is the choice for anyone who prioritizes rust prevention above all else. The base is infused with Rustrictor technology, which releases volatile corrosion inhibitors (VCI) that coat metal surfaces inside the box and stop oxidation at the molecular level. Pair that with the Dri-Loc O-ring watertight seal, and your hooks and jigs stay pristine even after a dunking.
The EZ Label system includes pre-cut, vented dividers that lock into place, allowing you to create customized compartments without any tools. The vent holes promote airflow, which helps moisture evaporate faster, and the included Water Wick packet actively absorbs humidity inside the box. The DuraView crystal-clear lid lets you spot the exact lure you need without popping the latches, saving time when the bite is hot.
The oversized latch opens easily with one hand, and the steel-pin hinges add durability. While this box holds 1.88 pounds of tackle max, it’s more than enough for a focused selection of 3-inch cranks, topwater plugs, and terminal tackle. It stacks neatly with other EDGE units thanks to the ribbed lid and base design.
Why it’s great
- Rustrictor base actively prevents corrosion
- Dri-Loc O-ring seal is fully waterproof
- Vented, pre-cut dividers for custom layouts
Good to know
- Shallower depth than some competing 3700 trays
- No desiccant cartridge included (Water Wick separate)
3. MoiShow Fishing Tackle Bag (Holds 4x 3700 Boxes)
If you already own a collection of 3700 boxes and just need a rugged carrier, the MoiShow bag is the practical choice. It holds up to four 3700 trays (plus one 3600) inside the main compartment, and the five mesh pockets on the interior and exterior handle pliers, scissors, and smaller tool pouches. The sandwich waterproof bottom—three layers of PU coating, EVA foam, and sewn fabric—keeps moisture from wicking up when you set the bag on a wet dock or in a boat bilge.
The KAM zippers are the standout hardware here: they have a smooth two-way action, meaning you can open the bag partially to grab a tray without unzipping the entire length. The non-slip shoulder strap material stays put even when you’re hauling a full load across uneven terrain. Externally, the bag measures 20 by 11.8 by 9.8 inches, which is a compact footprint for what it carries.
Reviewers have repurposed this bag as a lunch carrier or gear organizer, showing its versatility beyond fishing. For the dedicated angler, it excels as a modular storage system—buy your favorite 3700 trays separately, and this bag transports them all in one weather-resistant package.
Why it’s great
- Three-layer waterproof bottom prevents wicking
- Two-way KAM zippers for partial access
- Compact 20-inch length fits in smaller boat hatches
Good to know
- Does not include any tackle trays
- Shoulder strap padding is adequate but not plush
4. Ghosthorn 3-Pack 3700 Tackle Trays
The Ghosthorn 3-pack is a smart buy for anglers who need to organize multiple categories of tackle—say, one tray for soft plastics, one for hard baits, and one for terminal tackle. Each tray stands out with a 2-inch internal height, which is noticeably deeper than the standard 1.65-inch profile and allows you to store 3-inch cranks and larger saltwater lures without crushing the treble hooks against the lid.
Each box uses pre-cut adjustable dividers that rest flat against the bottom, preventing small hooks from crawling between compartments. The fully waterproof O-ring seal, combined with three cam-action latches, creates a tight closure that testers have confirmed stays dry even after being submerged. The hard plastic and resin shell is twice as thick as typical budget trays, so it resists cracking under the weight of heavy sinkers or when dropped on concrete.
The transparent lid lets you see contents at a glance, and the compact 10.63 by 6.61 by 1.97-inch footprint means you can pack three boxes side by side inside a medium duffel or backpack. A great middle-ground between the no-frills budget options and the premium single trays.
Why it’s great
- Extra 2-inch depth fits bigger lures
- Three latches per box for even sealing pressure
- Thick wall plastic resists cracks
Good to know
- No rust-inhibitor treatment on the base
- Three latches can feel stiff on newer units
5. Calamus DryVault Waterproof Tackle Box (3700)
Calamus’s DryVault 3700 is built for the angler who wants maximum waterproofing without paying a premium. The 360° waterproof gasket creates a complete seal, and the included desiccant cartridge actively absorbs any residual moisture inside the box, which is a rare feature at this tier. The shock-resistant and wear-resistant frame means it survives being tossed in a kayak hatch or stuffed into an ice fishing sled.
The adjustable dividers snap into place and feature small ventilation holes that allow air to circulate, speeding up drying after a wet trip. A built-in scale marker on the lid lets you measure fish or check hook sizes quickly—a subtle but practical addition. The see-through lid and removable label system make it easy to identify contents without opening every box in your bag.
Customer reviews consistently note that these boxes fit KastKing and other standard tackle backpacks perfectly. The single heavy-duty locking latch is easy to operate with one hand, though some users prefer dual latches for added security. For a dedicated dry-box solution for jigs, ice flies, or fragile terminal tackle, the DryVault delivers solid performance at a fair price point.
Why it’s great
- Includes a desiccant cartridge for moisture control
- 360° waterproof gasket provides reliable seal
- Scale marker on lid is a handy bonus
Good to know
- Single latch—less redundant security than triple-latch boxes
- Polyester material feels less rigid than hard plastic
6. LARIPOP 4-Pack 3700 Tackle Boxes
The LARIPOP 4-pack is the budget-friendly entry point for anglers who need to outfit multiple storage bags or give each fishing spot its own dedicated box. Each tray measures 11.49 by 7.28 by 1.65 inches, making them compatible with standard 3700-size bags and backpacks. The clear PP plastic gives you full visibility into each compartment, so you can spot the right color jig or hook without flipping lids.
The adjustable dividers are removable, allowing you to configure the interior for different lure shapes. The latches are sturdy for the price point, and the bottom of each tray has a groove cutout that makes it easier to pull the box out of a tight bag or boat compartment. Customers have repurposed these as snackle boxes for kids, craft organizers, and hardware storage, which speaks to the versatile design.
While the 1.65-inch depth is fine for standard crankbaits and soft plastics, larger saltwater lures or bulky swimbaits may not fit without pressing against the lid. The waterproofing is adequate for splashes but not intended for submersion. For the price-conscious angler who needs quantity over extreme durability, this 4-pack delivers reliable organization without breaking the budget.
Why it’s great
- Great per-unit price for a 4-pack
- Clear lid provides quick visual identification
- Adjustable dividers for custom layouts
Good to know
- 1.65-inch depth limits large lure storage
- Not rated for full submersion water protection
