Explorer & Probe combination instruments give you a tactile caries explorer on one end and a calibrated periodontal probe on the other — a complete diagnostic pickup in a single instrument. Common pairings include Explorer 23 with CP-2, CP-2B, CP-12, CP-15, CP-18 and WHO 11.5mm ball-end probes, plus Explorer 8 / 9 / Holst with the same probe set. Available in our ErgoDenta, ErgoLite, and ErgoLite X handle ranges. Balanced grip, mirror-polished tips, and laser-marked probe graduations that survive repeated sterilization.
