36IN STAINLESS STEEL DEEP CORE PROBE - The 36 in Deep Core Probe allows you to take soil; samples with a minimum of bending. The bulb end of the probe goes in easily and cuts a smooth soil core. You may core the same hole three times for nearly 3 feet of soil profile. The 304 stainless steel construction is strong and non-corrosive, and the slot back is heavily reinforced. The foot pedal helps you pull soil even in dry and stubborn soil. Breaks down into four pieces for compact storage.
