Save your back with the AMS Sure-Lock soil probe handle. Take samples up to 36" deep. Hand-crafted from 1018 steel which has been gold-zinc plated for added rust resistance. The handle height stays at the same level the entire time you're sampling which eliminates back strain. The hand-activated lever allows you to adjust the length of your extension rod. The Sure-Lock system eliminates the possibility of slippage unlike any other foot-pedal operated systems on the market. Choose from three different soil probe models or get them all in the complete sampling kit.
