Turn the switch fully counterclockwise to OFF to turn off the power. Turn clockwise away from OFF to turn on the power. When you rotate SENS from 0 to 10, the sensitivity will gradually increase. 0 is the lowest position of SENS; and 10 is the highest position. Generally, users can set SENS to high position. However, in mineralized areas or areas where electronic interference is used, it is best to reduce SENS appropriately.GREAT FOR KIDS - A telescoping arm provides length adjustment while a padded arm strap and comfort grip make this metal detector easy to use for kids of all sizes.
