Excellent, thanks for taking the time to share Rob, looked like an inspiring trip.

Slightly different machine and I’m coming from the local authority perspective so don’t pay for the calibration out of my own pocket, but do have to justify the annual cost of calibration to senior management. The PD series flashes up that it requires calibration after a thousand drills or a callender year, which ever comes first. (Usually the latter for us) We use the Resi PD400 a fair bit and the graphs do go in to reports for where we are condemning or retaining a tree. Having an in date calibration certificate as an appendix to a report gives the report more weight in my opinion. Also gives us confidence in knowing the motors are being looked at and service where necessary. I would think from your perspective (as you’ve already alluded to) it will depend on how often you utilise it as a tool.

Suspect this beech union would fail if one or both of these natural braces were compromised. Would be fascinating to sever one and see how long the union withstood the load.

Nice

Tried getting on but already booked, met Giovanni in Poland a few years ago, very engaging. Hopefully catch it at conference.

It is as Nepia suggests, Ps 👍

Some nice examples

Great edit Reg, an easy watch. Particularly like the reflection of the stick falling in the window @ 2:50 and the cat running away ! What makes you choose the battery topper for the stripping?

Poked it a few times over a number of years, so had a good idea of the level of decay.

I've posted this Red Oak before (evidence of both Ganoderma resinaceum & Ganoderma australe) but on passing today it was worth noting the decay process over the two years since it was felled. It appears that the reaction boundaries between the two decay zones of the G. resinaceum and G. australe colonies still remain quite lignified.

Apparently it does

Impressive that you have your own branded fungi !

Ganoderma spp. Possibly G. australe. Cocoa brown spore on the bracket surface and ivy leaves and white pore layer is the key here. Phaeolus schweinitzii has pale yellow spore.
