What are the long-term considerations of owning a DCP?
A1: Estimated 3-year maintenance cost of owning a DCP: 1. Unit is calibrated by the manufacturer. No further calibration is required. 2. There is a one-year warranty on all parts, provided they are used in the manner prescribed in the User’s Manual. 3. Upper and Lower Rods—The DCP is an impact instrument and its longevity is a function of the number of times it is used, the soil conditions, and the operator’s technique. Lower rods have failed at the weld below the anvil (4218 Models) because of fatigue, but most often because of abuse. 4. The Upper and Lower Rod on K-100 Models (with a quick connect pin) are more durable and last longer. This model uses stronger stainless steel rods and does not have a welded point at the anvil. 5. When used as recommended, the Kessler DCPs have lasted for years. After 13 years of manufacturing the DCP, we are delighted to report that only a few are no longer in service.
