In October 2009, Arnold and geologist Philip Mani located and recovered the largest oriented pallasite ever found, in Brenham, Kansas, using a metal detector he created himself and a unique mapping technique.

[7] The pallasite has been exhibited at:[8] In 2011, Arnold and Notkin found two irons, weighing approximately 544 grams (0.544 kg) and 34 kilograms (34,000 g), at 30 centimetres (0.98 ft) and 156 centimetres (5.12 ft) deep, respectively, while filming Episode 1 of Season 3 of Meteorite Men in the Morasko Meteorite Nature Reserve in Poland.

[9] The discovery of these specimens below the depth of previously recorded finds suggested that further, more detailed surveys should be conducted with improved metal detecting equipment.

Furthermore, the larger specimen was found embedded in a Miocene clay, which proves that it fell at that exact spot and was not transported by glaciers, disproving an earlier theory.

[12] In 2012, Detective Ryan Piotrowski of the Grand Junction Police Department charged Steve Curry with misdemeanor theft and fraud for selling false meteorites.
