VM-540 探測器定位器標配 512Hz、640Hz 和 33kHz 的探測器/攝像機頻率，使其與市場上主要的推式攝像機和履帶式攝像機兼容。 除了在探測器上方達到峰值的可視峰值條形圖外，還可以聽到匹配的聲音，在探測器上方時聲音最大。 VM-540 中的點陣顯示器以條形圖顯示峰值響應，以及匹配的信號強度數字、電池狀況、揚聲器電平、頻率設置和按下按鈕的探測器深度。
VM-540 探測器定位器配備“被動”電源模式，可檢測電源線的存在，以及一些從附近或架空電源線輻射 60Hz 的金屬管道。
VM-540 由兩節 AA 鹼性電池供電，通常可提供 20 小時的使用時間，專為可靠的日常使用而設計。

The VM-540 Sonde Locator comes standard with sonde/camera frequencies of 512Hz, 640Hz and 33kHz, making it compatible with the major push cameras and crawler cameras on the market. In addition to a visual peak bar graph that reaches its peak when over the sonde, a matching audible tone is heard which is loudest when over the sonde. The dot matrix display in the VM-540 shows a peak response in a bar graph with matching signal strength numbers, battery condition, speaker level, frequency setting and depth to the sonde with the push of a button.
The VM-540 sonde locator is equipped with a “Passive” Power Mode which will detect the presence of power lines, and some metallic pipes which radiate 60Hz from nearby or overhead power lines.
Powered by two AA alkaline batteries that typically provide 20 hours of use, the VM-540 is designed for reliable daily use.
