The Gardner ATTa Underlit Alarm is an ultra-compact and waterproof bite alarm that combines maximum reliability with a minimalist design. Thanks to its built-in transmitter, it works seamlessly with the V2 ATTx and Deluxe Receiver, while the anti-rock system prevents unwanted beeps. The rubberized soft-touch coating provides a quiet, non-reflective finish, ideal for stealthy sessions. The hard case serves as an on/off switch and protects the detector during transport. With snag ears, brass 3/8 threads and space for Tritium Max Betalights, it is fully customizable and durable. Low battery status is transmitted through the receiver. Available in multiple colors and comes with test battery. Compact, stylish and built for reliable performance on the waterfront!
