Useful precision, Bosch GMS120 is sold under (at least!) Two different names "Professional" and "Wall Scanner" according to its destination market Europe, North America ... (still under item no. 0601081000 Bosch) .They differ that by replacing mode "Drywall" with "wood" without impacting performance and still appears to date at a very competitive price under the name Bosch GMS120 "Wall Scanner" at West Audio FR. Apart from the most favorable Research configurations for which the results are reliable, the device is sensitive to many parameters such as static electricity, humidity, magnetic fields and its direct environment .. indications are sometimes confusing. With practice and compliance with statements generally happens by cross between different detection modes to target so (more or less) accurate metal, electrical cables and sometimes wood (less convincing), but not in all cases .. .and not for sure (in the knowledge that no detector in this category is 100% reliable!) .Before buying, I tested the Bosch PMD10, the operation and the results are finally very close ( the price of the 2 models are sometimes neighbors, rather prefer the "pro", otherwise the PMD10 is a valid alternative) and I had the opportunity to use the most simple but effective Bosch PDO 6 for those who have only metal or energized cables to detect (but limited in depth performance), again the price difference with the model pro GMS100M (bulkier but more powerful) is sometimes tenuous and worth thinking ... Note the possibility to register on the Bosch website "Pro" or "special" (type "Bosch 3 year warranty") for a free extended warranty to 3 years!
I acquired from the Skil F0150550AA (Skil Bosch using the technology for its devices, for the story is the clone of Bosch PDO Multi plus distributed by Bosch under its own brand, a shame given its good performance compared to the "pros" models of the "official" ???? range) and can confirm positive tests (eg. short video on Youtube but proven comparative aves Bosch GMS120) that make it probably the best quality / price search detectors, with superior sensitivity (despite a lower depth detection ???) in the metal and cable research, for wood of 2 does not allowed me to find my reliably beams under 1 to 2cm plaster .... I recommend it, even if it is not immune to defects of this type of aircraft, its indications have been more reliable and honest as its "big brother" pro, for a contained price. Only regret, the lack of backlight, display less "successful" and fragile felt skids.
