You could leave a laminated sign on a wooden post saying something like 'This site is being monitored by concealed video cameras'. They could spend all day looking for them. On a purely abstract level I do like the photo of the plastic ;)

The residential home has a roof terrace so they can watch the cricket - when it's not raining!

That does look interesting actually, if a bit pricey - but if the pricey translates into tough, then I guess it's worth it - certainly for work. But it's a lot of money for caving use only.

This guy has sort of a skateboard:

Isn't that the case with all insurance everywhere though? Statistically, I suspect most people paying insurance 'lose their money' - in the sense that nothing bad ever happened, and so they never made a claim, and just paid off their premium. It's much rarer for something bad to happen, and you...

More than once in the last couple of months I've had to shoo people away from deep open holes on CROW land - and their dogs in some cases, which weren't on leads, and with sheep grazing on the same land. In that case the owner was completely uninterested in my reasoning, so I walked away and...

Same here! From the amount still stuck on me from work, Sikaflex All-in-One is probably the best bet. But yes, don't get it on your carpet... I also use clear Gorilla Glue for repairs, which is very flexible.

On a roof in Settle and this just went past.

90% of my caving is (inevitably in Derbyshire) on very dirty ropes ;)

Yep - pretty much sums up all my concerns! Aluminium is too soft for much friction - I replaced my Banana bobbins with custom stainless ones for that reason - only recently flipped them after four years of solid use. Plus you can use a Raumer Handy for - well, I've had mine six years, and I...

I use Excalibur 8mm screws and have generally been happy with them. Last week I pulled some out of a bolt-climb and reinstalled them higher up, but they'd only been in a week, and not in very hard rock, so I figured they'd be OK. I always use a nylon washer between the screw and the hanger as...

I've never used a Freino, partly as I was so happy with the Raumer Handy I've never used anything else. My main concern with the Freino is the friction spur appears to be 90° off-line for the descender rope path. But I know Andrew swears by them, so I wouldn't want to diss them when I've not...
