The Promar 2 Speed Bait Aerators are quiet and water resistant.
These high quality aerators have been tested and proven to perform day in and day out. The internal piston pump is controlled by a 2 speed setting switch.
The high setting allows for maximum aeration, while the low setting conserves battery life. Each aerator includes 2 sets of air tubing and air stones. The 720 model uses 2 D-cell 12v batteries and lasts 30 hours.
