The ST-510 uses a rechargeable battery. To replace it, remove the battery compartment cover (usually located on the back) and disconnect the old battery. Consult the user manual for detailed instructions.
The ST-510 transmits at multiple frequencies, typically 512 Hz, 8 kHz, and 33 kHz, to adapt to different line conditions. Check the manual for exact frequencies.
No, this transmitter is for tracing metallic lines. For non-metallic pipes, you would need a sonde probe or other specialized equipment.
While it's professional-grade, its compact size and ease of use make it suitable for contractors and serious DIYers who need to locate underground lines.
Locates cables perfectly. Worth every penny.
I rented one of these before, so I knew it worked. This is a great price. It's easy to use and the signal is strong. Only downside is that it's heavy, but it's professional gear.
I'm a plumber and often need to find underground lines. This transmitter is a life-saver. It connects easily to any metallic pipe or cable. The 10-watt signal is powerful and gets detected reliably even at depth. The build quality is rugged. I've used it in wet conditions with no issues. A fantastic investment for any professional.
You need some training to use this properly. The manual is not very helpful. With a locator receiver (sold separately), it works, but don't expect plug-and-play.
I've been wanting one of these for a while. At this price, I couldn't pass it up. It's the real RIDGID unit, no knockoff. Works perfectly with my SeekTech receiver. Highly recommend.
Feels durable and the controls are intuitive. The battery charge lasts a good while. It does its job. I wish it came with a carrying case, but that's minor.
I use this for locating utility lines on construction sites. It's accurate and reliable. The multiple frequency options are useful. It's a bit pricey even on sale, but it's a tool you'll have for years. Definitely worth it.
The output connector didn't work. I could attach the leads, but the signal wouldn't transmit. Sent it back for a refund. Maybe I got a lemon, but be cautious.
