The Badger-Eclipse Drills are modified Eclipse Drills originally manufactured by Icefield Instruments, Inc. The drill is an electromechanical system capable of collecting 81 mm (3.2-inch) diameter core to depths of approximately 300 meters. The drill system is transportable by small aircraft or helicopter. IDP has two Badger-Eclipse Drill systems that it regularly deploys and a third Eclipse Drill that was transferred from the University of New Hampshire to IDP at the University of Wisconsin in 2010.
In 2013, IDP designed and fabricated a solar and wind power system for use with the drill, which has proven particularly useful at field sites where environmental impact is of concern and where use of a generator is not desirable or permitted. IDP also owns two Mountain Hardwear Space Station tents for use with the Badger-Eclipse Drill systems. The tents have allowed drilling operations to continue safely and reliably during inclement weather in Alaska, Greenland and Antarctica. In 2017, IDP completed a redesign of the aging control boxes and readout boxes to provide for simplified operation, weight reduction and new sealed cases. In 2018, new cover panels were implemented for the traversing system. New cases were also procured for the motor section and tower frame. New load pins and load pin amplifiers were implemented to make the load sense circuit more robust.
Two Badger-Eclipse drills are available for use. One is referred to as the ‘standard’ Badger-Eclipse Drill and the other as the ‘traversing’ Badger-Eclipse Drill, since it is sled-mounted. In late 2016 and early 2017, IDP performed a thorough assessment of the Eclipse Drills and has since implemented numerous minor, but very beneficial modifications to the drills.
