HC-SR04 max practical range outdoors — ano experience niyo?

Datasheet ng HC-SR04 sabi 4 meters max range, lab conditions yan I assume. For our outdoor obstacle course (sumo bot territory border detection), kelangan ko ng reliable detection at 2 meters minimum.
May nag-test na ba ng HC-SR04 sa real outdoor conditions? Wind, surfaces of different reflectivity (cardboard vs metal vs cloth), bright sunlight — does it actually hit 4m or am I capped at 1.5m practical?
If HC-SR04 is unreliable outdoors, ano gamit niyo? VL53L0X laser? Sharp IR rangers? Curious what survives field conditions.
