Discussion: Has anyone tried a Fence Devil

We have an event coming up where the forest is bounded by fairly high barbed wire fence. We will probably use stiles, but I did see this easy alternative and wondered if any club (probably in the US) was using them:

great idea but I wouldn't pay $200+ for it. Get some PVC pipe - cut in half lengthways for the horizontal parts. Cut into appropriate lengths for the vertical parts, shape the ends to match the curve of the horizontal parts. Assemble in the field with duct tape.

Presuming that the Course Setter would install and map these things, it would be an interesting calculation for runners to figure out how far to divert from an intended course, in order to enjoy crossing at a Fence Devil. As opposed to just rolling under the lower wire, and continuing on without diversion.

I think most orienteers would rather do the old 'duck and roll' instead of wasting time looking for an installed Fence Devil.

Unless you put the fence devils at the most likely crossing points, or adjacent to controls.

Just remember, as per the manufacturers' instructions, to unload your weapons before using it.

Why bother with PVC, just use a stick

We have to get 200 people through the same crossings multiple times and minimise fence damage, not sure a stick is going to cut it.

If you want to cut the fence then I'd suggest boltcutters

How about an above ground pool ladder?

....or any of the dozens of traditional farm stiles, still in use worldwide.

A fence devil, whether commercial or homemade, is going to be a lot easier to carry than many of the alternatives.

Yep, going down a fence devil type route looks most likely. Thanks for the suggestions, I'll be using traditional stiles the same time I convince my dad to fly down and build dry stone walls for the start lanes.

I recall seeing hot water pipe insulation used, with duct tape. (This insulation looks a bit like the pool noodles sometimes used as flotation aids when swimming, but hollow core.)

A cheap and ultra-lightweight alternative might be using nylon cable ties to hold 2 or 3 fence strands together (creating a gap), and possibly adding JimBaker's pipe insulation and duct tape to cover any barbs.

Fence devil? What an odd name!
Why not call it what it is - a Fence Wire Prier?

Spoken like a true orienteer, Gord. :p

Bunnings to the rescue - 32 mm split conduit seems to work well on the gauge of wire in use on that property.

(trip down was the first time I've driven through a ford and met a turtle swimming the other way)
