Keep minnows, shiners, and other baitfish alive and active while chasing crappie, walleye, or trout with the Marine Metal Bubbles Air Pump, a compact aerator capable of handling up to 8 gallons. The precision motor runs about 100 hours on two alkaline D batteries and will still operate on one, pumping 1.0 STL per minute through a weighted air stone and 30 inches of silicone tubing. A rugged, impact- and water-resistant case with neoprene seals, a rubber booted switch, and beryllium copper battery contacts extends durability and battery life. Each pump is tank-tested for quality and comes with a large, adjustable stainless-steel clip for easy attachment to any container, plus a Dry Box clamshell package that keeps the unit protected during use in both fresh and saltwater.Aerates up to 8 gallons with 1.0 STL/minute outputRuns about 100 hours on 2 alkaline D batteries, also operates on 1 batteryWeighted air stone with 30' silicone tubing enclosed in pumpImpact- and water-resistant case with neoprene seals and rubber booted switch
