The Opti-Finder also has an added benefit over most other transceivers on the market. To misquote from Spinal Tap, “Yes, but ours goes to eleven.” According to Life-Link, the broader volume range “allows the searcher to increase the volume faster in a fine search and it makes it easier to detect subtle changes in signal strength.”
Also available is the Pieps 457 ($285) without the LED visual indicators. Both models come with a nylon webbing neck/body belt equipped with a positive locking buckle. Earphones for both models are optional and go for an additional 20 smackers.
