Hi and welcome to the forum.
I just played with you on the Siege of Tobruk map, IIRC. I sat in the leFH18 and you spotted.
Your spots became better and better during the game, just a tip:
Sometimes if you spot a tank e.g., you shouldn't aim for the tank itself, but the floor under it, because the spot might go "through" the tank and then you'll have plain desert as a spot.
