Spent $150 on a new anti-two block sensor and it paid off already

I had a cheap knockoff sensor on my Grove RT and it kept giving false alarms. Finally dropped $150 on a proper one from a local dealer in Birmingham. Second day with it, I was lifting a steel beam near a power line and it caught a close call I almost missed. Anyone else had a cheap sensor nearly cost them a job?

Yeah that's not really an anti-two block sensor though is it. An anti-two block is for crane boom tip height, not for power line proximity. You're talking about a proximity alarm or some kind of line voltage detector. Those are different things. The anti-two block prevents the hook block from hitting the boom tip, it doesn't sense nearby power lines. But honestly for $150 I'd be curious what brand you actually got cause most decent voltage detectors run way more than that. Hopefully it does the job though cause power line accidents are no joke even if the name's wrong.

Yeah you hit the nail on the head @tara345, the name is all wrong but it happens all the time with this kind of equipment. It reminds me of how people call every brand of tissue Kleenex or every photocopier a Xerox. The name just sticks even when it is not accurate. I have run into guys on job sites who call any safety sensor an anti-two block because that is the one they hear the most. It can be confusing if you are actually trying to order the right part or troubleshoot something. Hopefully that voltage detector works out for them anyway, because even if the name is wrong, anything that keeps you away from live lines is money well spent in my book.
