second hand resistographs

[arnoldbuchsassinger]

Anyone know if they are available, if so in decent condition, need one but cannot justify £4000, i want a device which creates a paper trail, logs the output.

Is that the price these days, 4k?

 

whats the new 400 priced at

 

you could look at rinntech prices too

Was talking with Sorbus yesterday about the 400, as it happens.

 

I believe it's around £6.5 k

 

Will probably look down that route when the DmP is no more.

 

t/R is generally what I need & Tomographs draw too much atttention & take too long to set up imo.

they would do well to offer thee and me one at trade:001_rolleyes:

 

if they did, they would get lots of coverage!

Picus is revamping theirs to eliminate the need to connect 2 cables together, etc; rollout early 2012 i am told. others only have 1 cable now and are quicker; just fyi not selling, though i like tomos in general because i do not like t/r--bollocks imo. then again attention is not such an issue for us as it is for muni folk--wait, doesn't resistographing draw attention too?

 

i looked at the snazzy new resisto last month at a trade show; digital all the way, quick pic etc. $8000 US. coincidentally after i got home the chaps from the power company to test my pole (the one holding up the wires) with the very same tool. The lads were not excited about using it--they knew they could "see" signs of inner defects quite well without. cheeky youth.

The micro drills are far quicker to set up and extract useable data than the tomographs.

 

As for the spermatazoidal containers you refer to, formula is a necessity for basing a report on, whether that be the one our long haired friend from the Karlsrue Institute originated or the one Iowas own Dr Coder devised.

 

An additional tool to for the armoury, that adds to the decay detection devices, probes, hammers or good old gut instinct

"The micro drills are far quicker to set up and extract useable data than the homographs."

 

While it's not a good idea to race when assessing risk, I wonder how much quicker vs. how usable the data is. Using fakopp's arborsonic takes us < 15 minutes of field time, to get an image at one level.

 

"...formula is a necessity for basing a report on, whether that be the one our long haired friend from the Karlsrue Institute originated or the one Iowas own Dr Coder devised."

 

t/r or any formula may be useful for some trees, but (in a different land) i've only found it a necessity to use for a few. for significant muni trees i'd be more likely to use formulae, so i think i understand your perspective. but as far as the basis of a report, see #7 here http://www.fs.fed.us/foresthealth/technology/htwc/Docs/04-Matheny-Top_10_Lessons.pdf

 

I've studied biology at the feet of the iowan for lo these many years, but the engineering calculations that are applied to trees, from that or any source, I--and several others more skilled than I-- have found wanting. "Trees are not pipes" as Nelda puts it. I much prefer introducing mitigation scenarios and prognoses of residual risk much earlier in the assessment process, while most unfortunately seem to prefer quixotically questing for The Number.

 

From what i've seen of your work, i could learn a lot about mitigation from you, so maybe we take slightly different routes to the same goal. But Iowa is next to Missouri, and in the US "I'm from Missouri" is a saying that reflects skepticism, which is where I'm at on applying, or certainly relying on, engineering formulae to most biodynamic entities, whatever their contents.

 

That's why the tomo far outstrips the drill in terms of usable data imho. Maybe they could sell shrouds for you high-profile guys--"Pay no attention to the man behind the curtain!"--or set up some kind of nearby distraction...?

Now there's a thought.
