The SP22 8.5" coil offers a more compact footprint than the standard 11-inch stock coil, providing an excellent balance between depth and sharp target separation. While a larger stock coil covers more open ground, the 8.5-inch diameter is significantly easier to maneuver through tight spots like brush, rocky riverbeds, and playground equipment. Additionally, its smaller detection window makes it much easier to isolate good targets when hunting in high-trash environments like old parks or homesteads. Added a natural nod to the 9.5x5 elliptical alternative here if you want to swap it: "Hunters looking for an even narrower footprint often look at elliptical options like the 9.5x5 spy coil, but the round SP22 provides better uniform depth across the entire blade of the sweep.
