Beaver Dam Black Hole Covers (3-Pack): Complete Freeze Protection & Multi-Hole Stealth

Equip your entire tip-up spread with the Beaver Dam Black Hole Covers 3-Pack (BD-HC3). Designed for hard-core ice anglers, this convenient multi-pack gives you full coverage across multiple setups, keeping your holes completely slush-free and ready for action. Each heavy-duty insulated cover seals out howling sub-zero winds while trapping geothermal heat rising from the water beneath. By stopping skim ice before it starts, these covers preserve your bait's natural movement and eliminate the hassle of constant re-clearing.

Constructed from ultra-durable dark black composite, these covers naturally absorb ambient solar heat while blocking surface light from penetrating down into the water column. Eliminating light beams keeps shallow-water trophy walleye, crappie, and pike from spooking, creating a calm, natural strike zone directly below your rigs.

Key Features

• Value 3-Pack Coverage: Protects up to three holes simultaneously, giving you a complete thermal barrier for your main tip-up line or ice shelter footprint.

• Thermal Freeze Shield: Insulates drilled holes against extreme sub-zero temperatures, drastically slowing ice formation and letting your line run smooth.

• Light-Blocking Stealth: Deep black material prevents surface glare and sunbeams from shining through, keeping wary fish confident in clear or shallow water.

• Cold-Weather Durability: Molded from flexible, crack-resistant materials built to withstand brutal arctic conditions without shattering or warping.

• Quick-Access Slot: Features a pre-cut notch so you can slip the cover on or off around active fishing line without disturbing your tip-up trigger or depth setting.

Technical Specifications

Pro Tip: Pack a ring of soft snow around the outer perimeter of each hole cover after setting your line. Pressing snow along the lip creates an airtight gasket that prevents freezing drafts from blowing underneath, keeping your holes wide open even through sub-zero overnight sets.
