VM-480B“Split-Box”埋地公用設施定位器是一種多功能定位儀器，設計用於定位和追踪管道和電纜的路徑以及檢測通電的 50/60Hz 電力線。 分體箱設計可以輕鬆進行盲搜索、地面調查和定位地下金屬塊。 可以使用三角測量法計算掩埋公用設施的覆蓋深度。
VM-480B 因其獨特的設計而獲得了 Split-Box 的綽號。 盒子設計分為兩部分。 一個是發射器，它發出定位信號。 另一部分是接收器，它接收來自發射器或線路輻射 50/60Hz 的信號。
將定位器安裝在可選的搜索手柄附件上可以簡化盲搜索、地面調查和地下金屬塊定位的任務。

The VM-480B “Split-Box” buried utility locator is a versatile locating instrument designed for locating and tracing the path of pipes and cables and detecting energizing 50/60Hz power lines. The split-box design makes it easy to conduct blind searches, ground surveys, and locate underground metal masses. The depth of cover to the buried utility can be calculated using the triangulation method.
The VM-480B gets it’s Split-Box nickname by its unique design. The box design separates into two parts. One being the Transmitter, which sends out the locate signal. The other part being a Receiver which picks up the signal coming from the Transmitter or line radiating 50/60Hz.
Mounting the locator on the optional Search Handle accessory simplifies the task of conducting blind searches, ground surveys, and locating underground metal masses.
