Spear Shack at 1956 Sunset Cliffs Boulevard is a specialty spearfishing pro shop stocking spearguns, pole spears, freedive wetsuits, low-volume masks, and long-blade fins calibrated for Southern California kelp-bed hunting. The shop's custom rigging service assembles and tunes speargun setups to individual shooting style, adjusting band load, shaft weight, and reel drag for the specific species a diver targets, using the same coastal access points served by Mike's Boat Rentals nearby. Inventory covers both entry-level Hawaiian-sling kits for beginners and competition-grade enclosed-track rail guns for bluewater hunters chasing yellowtail and white seabass offshore. Wetsuit selection runs from 3mm shorties for summer reef dives to 7mm hooded full suits rated for the 55°F thermocline drops common below the Point Loma kelp canopy. The Sunset Cliffs Boulevard location sits within OB's broader watersports retail strip that includes surfboard and skate gear at Ocean Beach Surf & Skate on Newport Avenue. Bluewater speargun builds for offshore tuna and yellowtail runs represent the shop's highest-complexity work, with custom shaft lengths, breakaway rigs, and float-line systems assembled to order.
