The Ortz Ultrasonic Dog Whistle is the budget-friendly ultrasonic option that appeals to owners who want high-frequency cues beyond human hearing without spending on top-tier brands; its low price and simple adjustable slider make it accessible for casual training and recall. Technically it trades some consistency and brand trust for value—useful for discreet signaling but less robust in windy or noisy conditions compared with metal or competition-grade whistles here.
