The Brunson 1.5THDN Drift Nest—often referred to as a "hockey puck"—is a temporary, magnetic SMR adapter designed for flexible placement in virtually any measurement environment. Its flat back allows you to adhere it to surfaces like machine tools, concrete floors, pillars, or stands using hot glue or general adhesive. While the magnet holds the SMR in place, the adapter itself is not self-securing.

Built from black anodized aluminum, this drift nest is durable, lightweight, and reusable—ideal for field setups or quick changes in reference points. Compatible with any 1.5" diameter SMR, it offers precise alignment with a center height of 1.125" (28.6 mm). For a budget-friendly alternative, consider the 1.5THEDN economy version.
