In a blender, combine the vinegar, capers, honey and about half of the dill and tarragon and blend until smooth. While blending, slowly add the olive oil to emulsify. Season with salt and pepper. Reserve at room temperature for finishing.
Score the scallops by making 1/8-inch-deep crosshatches across the top side of each (like a checkerboard). Season with freshly cracked black pepper. Dry the scallops thoroughly on paper towels.
In a medium saute pan, heat the canola oil over medium-high heat until it just begins to show ripples. Place the scallops scored-side down into the oil for 2 to 3 minutes. Add the butter to the pan and flip the scallops over; cook for 1 more minute for medium rare. Season with salt.
Place the scallops on a serving plate and spoon some of the caper-honey sauce over the top. Top with the remaining tarragon and dill.
