Prepare the wooden skewers by soaking them in water for one hour.
Preheat your Z Grills pellet smoker to two distinct grill zones: one medium (325°F-350 °F) and one medium-high (375°F-450°F).
While your pellet smoker preheats, prepare the scallops. Gently peel away the side muscle from each scallop, if needed. Pat scallops dry with paper towels.
Carefully thread four scallops onto each skewer and place them in the fridge.
When the grill is preheated, place a small saucepan over the medium heat zone. Add butter to pan and cook, occasionally stirring, until the butter is brown and nutty (4-5 minutes).
Remove from heat and immediately add minced garlic and the juice from half a lemon. Season to taste with kosher salt and more lemon juice. Set aside.
Prepare the grill grates over the medium-high heat zone by rubbing them with a paper towel soaked in vegetable oil.
Lightly brush the scallops on both sides with vegetable oil. Then, lightly salt them with ½ tsp of kosher salt.
Grill uncovered until you see dark grill marks on the bottom of the scallops (about 3 minutes). Then, flip and grill for 2-3 minutes more until the scallops are just barely cooked through.
Transfer scallops to a serving platter and drizzle with the lemon garlic butter. Serve with lemon wedges.
