Affordable Replacement Sondes for Contractors Using Digitrak Locators

Looking for affordable replacement sondes for your Digitrak locator? HDD contractors trust Cortek Power for high-quality, fully tested transmitters that perform under pressure—without breaking the bank.

Every directional drilling contractor knows the value of reliable tracking equipment. Your Digitrak locator is only as accurate as the sonde powering it. These transmitters are the heart of your guidance system, feeding live data on pitch, depth, temperature, and more from beneath the surface. But when a sonde fails—or when you need to gear up for a new project—replacing it shouldn’t mean spending a small fortune. That’s why contractors using Digitrak locators turn to Cortek Power for affordable, dependable replacement sondes that are ready for the field.

Why You Need a Reliable Replacement Sonde

Horizontal directional drilling (HDD) projects live and die by the accuracy of their tracking systems. A weak or failing sonde can result in a misaligned bore path, delays, or even costly underground damage. That’s why having a reliable, high-performance sonde isn’t optional—it’s a necessity.

Digitrak sondes are designed for compatibility with their respective locators, whether it’s from the Mark Series, Eclipse Series, F2, FT2, or F5 lineup. Each model delivers precise information tailored to your drill’s current conditions. However, when that sonde goes out of spec, it’s critical to have a replacement on hand—one you can trust to perform just as well as a new unit.

But replacing your transmitter with a brand-new one directly from the manufacturer can cost between $1,100 and $2,000. That’s a serious hit to the budget for any contractor running a small team or managing multiple drills.

Why Refurbished Sondes Are the Smart Choice

Refurbished doesn’t mean second-rate—it means smart, strategic savings. At Cortek Power, we specialize in refurbished Digitrak sondes that are fully tested, calibrated, and rebuilt to meet original manufacturer specifications. Contractors save hundreds per unit without sacrificing the performance they rely on in the field.

Whether you’re replacing a sonde that finally wore out or need extras to support multiple drilling crews, our transmitters are ready to go. We stock sondes for every Digitrak locator series, and we make sure each one is locator-ready before it ships.
