The 7/8” AMS adjustable foot step works on all 7/8” diameter AMS soil probes and 5/8” AMS extensions. The 1” foot step is used with the 1”x36” replaceable tip soil probe.
The adjustable foot step allows for additional down pressure to be used to drive the probe. The foot step can be adjusted to fit anywhere on the soil probe or extension so that deeper samples can be taken.
*Note: The AMS Adjustable Footstep does not work with AMS gas vapor probe or tile probe extensions.
