Makita DWD181ZJ 14,4 V/18 V Li-ion LXT wandscanner geleverd in een Makpac-behuizing - batterijen en oplader niet inbegrepen

L'avevo comprato per utilizzarlo come pacometro, ossia per rilevare la presenza di barre di armature all'interno del calcestruzzo. Lo strumento ha fornito indicazioni molto contrastanti nel corso dell'utilizzo: effettuando piu' passaggi sulle stesse aree (spostando lo strumento in avanti e all'indietro) sembra fornire informazioni piu' accurate.Mi ha molto deluso in occasione dell'indagine eseguita all'intradosso di una trave emergente in c.a. dove ha segnalato la presenza di 2 ferri, mentre alla rimozione dell'intonaco e del copriferro sono uscite ben 6 barre di acciaio a solo 1 cm di profondita' (le barre erano distanziate e non particolarmente ossidate).Insomma lo strumento funziona in maniera troppo random.Sconsigliato per un uso professionale.Peccato perche' e' un prodotto molto ben fatto e con display all'altezza.La durata della batteria e' piuttosto lunga: per sessioni lunghe dotarsi di una seconda batteria, oppure portarsi appresso un caricabatterie (la carica e' piuttosto veloce, e si puo' caricare la batteria mentre si fanno altri lavori).Nel complesso: giudizio negativo

update: I was on makita site looking for more information and I realized there was a manual that should have come with the tool. Talk about simplifying the process…i’m not much for manuals, but this one is a must or at least saves a lot of trial and error, bumbling around. So if you get one without a manual - head to makita’s website and read it first.There is hardly any documentation and learning to interpret what it tells me is probably the bigger issue. I am also color blind, but truthfully don’t know whether that matters or not. I have to say that if makita made a 10 minute video on interpreting results, this would be worth six stars! The impetus for buying this came with me needing to try and locate a drain line in a concrete slab to tie into. Yes I could just start jack hammering, but all the duct work and some of the electrical is buried in the slab as well as the plumbing. The last thing I want to do is make a nightmare out of a bad dream.So what I have done, is started using it where I know there are stuff in the slab. Like next to a register where I know duct work ties in. Unexpectedly, the duct work doesn’t make a dot, but you can see the void in the concrete. Amazingly, this slab has welded wire and the machine actually measures the spacing. I have figured out that the dots are not to scale - which was my initial quandary - is it rebar or is it refrigerant piping??? I can tell one by depth and secondly because of the repeating pattern.I have also found that a dim room makes the tool much easier to read the subtleties of the display. in radar mode it doesn’t display the depth. I believe that the display from top to bottom represents a cross section of the slab from top to bottom, sort of like a slice from an MRI and not an x-ray like I originally anticipated.The last picture is in “panel mode.”. There is a 3” copper pipe at this location which is indicated by the bright display. in panel mode studs seem to appear as a dull linear artifact.As I said, I think there is quite a bit that an experienced user could tell me and with trial and error, I hope to get there. it really is an amazing piece of tech…however, 5 years from now it will probably look like an Atari 2600 as opposed to a PS5😊.

All is good!

It was suppose to scan through wood, and penetrate at least 4 inches. It didn't. I was hoping to find my floor joists. I think it found something but the images where not clear. The wood floor was 1-1/4 inch plywood. I had no confidence in the device. I tried to find my roof joists but the results were worse. It would not scan through composition roof tiles and 5/8 inch thick plywood. The directions did not address any of these, what I thought was common things the homeowners would scan for. I particularly wanted to find my roof joists as I am adding solar. There is really nothing out there to scan for roof joists that I could find.
