Your job is to log that forest the environmental protesters may or may not have sabotaged last week.  Are you going to cut it by hand because it’s too dangerous to use a chainsaw?  Heck no!  You break out your RENS P-4000 Metal Detector.

RENZ designed this self-calibrating, fully automated metal detector especially for logging.  It doesn’t require any manual adjustments, so there’s little or no training needed to operate it.  Just make sure there’s no metal nearby, then pass over the entire surface of the log or tree with overlapping sweeps to ensure you’ve scanned the whole thing.

Weighing in at 7-1/2 pounds, the durable, battery-powered unit runs for 10 hours on a charge, and the power’s regulated so as the battery runs down, the sensitivity won’t decline.  You can adjust the sound level from 0-100 dB, and the unit adjusts from 51-1/2″ to 57″ in length.

The P-4000 ships with earphones, shoulder strap, battery pack, charger, and poly-form carrying case.  You’re going to pay $1,400 for this metal detector, but saving your crew from a chainsaw-related injury is worth it.

    Eco-terrorists in the Pacific Northwest switched from ferrous spikes to ones made of a ceramic material to avoid detection. IIRC, several loggers were seriously injured by chains broken by those units. IMO, anyone cowardly enough to spike a tree should get to meet a chipper up-close and personal.

    yeah, make them one with the earth they love so much

  3. Old-Coot: I hadn’t heard about the ceramic spikes, but it doesn’t surprise me.

    I didn’t really want this post to be about eco-terrorists, but I wrote it knowing full well why products like this exist.

    It’s a shame that some people value other peoples lives so little — yet I’m sure they value their own life above all else.

    It’s not like logging is the safest profession in the world, but they don’t need the added risk. These are just guys like us trying to feed their family.

    I personally think anybody found spiking trees needs to be charged with nothing less then attempted murder (premeditated at that) and given the maximum penalty the first time.

  4. Old Coot says:

    Below is the url for a long dissertation about tree spiking written by someone who supports the concept. The use of ceramic spikes is noted at the top of page #5.


  5. After reading the above link the guy even though he tries to frame a rational argument his final paragraph betrays his true nature.

    “If people in the future do get hurt through responsible Spiking, it is the responsibility of the Forest Service and and timber companies involved; they had been warned.”

    I think that says it all.

    Calling this “eco-terrorism” is off base. if I get on a crowded bus with a bomb that is wrapped with nails and set it off, I am a terrorist. To call this a terrorist act waters down the word. Trees often have foreign objects in them, like rocks, nails from old wires or fencing. This all goes back to a single incident over 20 years ago. The cause of that incident is debatable. So if someone runs a company and does not follow safety guidelines and that kills a worker are they a “empoyo- terrorist’? Are drunk drivers (20,000 deaths a year) auto-terrorists.?

    Can’t we all just talk about tools?

  7. Eion says:

    Asbestos: the presence of foreign objects in trees is one thing, deliberately putting them there to slow down logging (at the risk of injuring loggers – especially given that the spikes can’t be seen) is quite another. Your analogies of negligent employers and drunk drivers are not on point, because in those other cases the underlying intent is not there. Terrorism may be a little strong, but the people involved style themselves as ‘eco-warriors’, so it doesn’t seem totally overblown to me.

    If you want to slow down a logging operation, there are peaceful ways of doing it that aren’t likely to injure anyone: sit-ins, for example, or deflagging trees that are marked to be felled. Spiking is just low.

  8. Davo says:

    Tree-spking has been denounced by environmentalists for years…I find it very hard to believe that this is still a common hazard encountered by loggers.

  9. cliff says:

    @ davo, even though tree spiking has been “denounced” it still happens quite a bit, even their own people admit that the “denouncement” was just lip service to get the FBI off their a$$. and yes drunk drivers are auto terrorists.
