Sportsman's Warehouse opened its Santee location in October 2022, filling an 18,500-square-foot former Office Depot space at 240 Town Center Parkway with over 60,000 SKUs of hunting, fishing, camping, shooting, boating, and outdoor-cooking gear. The firearms department holds a Federal Firearms License and offers national gunsmithing services, while an interactive digital board near the entrance displays real-time San Diego County fishing reports including stocking schedules for Santee Lakes — a resource that complements the outdoor-lifestyle feed and supply inventory at Hawthorne Country Store Santee on Woodside Avenue. Region-specific product curation targets East County San Diego conditions, stocking tackle rigs for warm-water bass and catfish at Santee Lakes alongside cold-weather layering systems for alpine deer and elk seasons in the Cuyamaca and Laguna ranges. The chain, founded in 1986 and now operating over 110 stores, anchors a Town Center Parkway outdoor-recreation cluster that includes the craft-beer taproom at BNS Brewing and Distillery. on nearby Wheatlands Avenue. Highest-value services include custom rifle-scope mounting with bore-sighting calibration and trigger-pull adjustments performed to manufacturer specifications by the in-house gunsmith.
