I think that from today's test results (thanks Reg and Wombat) that we can safely assume that the QED can detect larger targets at depth.So it would appear that the QED has the sensitivity to small gold comparable to the SDC and at the same time will be able to detect deeper nuggets if they are there. The independent test results confirm earlier test results.
Yep totally agree Doug.
Without cherry picking, some analysis from the chart for the yet-to-be-formed "QED Marketing Dept"
Comparing brands / models & giving the 243* aggregate score as 100% to the GPX 5000, the industry PI standard (some say), the following shows a comparison as a %
(* Using Aggregate Scores, all round score on small - large metal targets on ground in air tests)
Aggregate Model Score Comments
Score* (rel. to GPX 5000)
157 2300 64% lower cost, easy to use standard for smaller gold
163 ATX 67% US made PI standard, affordable
226 GPX 4500 (12” EVO) 93% the PI target for GR & critics
232 GPZ 7000 (14”) 95% "the disappointer" BUT may offer some advantages
241 QED (12” EVO) 99% Aust made challenger: most affordable, lightweight & good performer
243 GPX 5000 (12” EVO) 100% the industry PI performance standard, good all rounder
* on 17 metal (mostly standardised ie reproduceable) targets (v. small - large, gold, coin alloys & aluminium)
Comparative test results gathered since April 2016.
The test distances are in Inches.
The AL* test pieces are all 3mm thick except the AL block.
Might be worth interested parties looking at the COMPARATIVE TEST RESULTS BUGs posted between the QED, 7000 & 5000 again in the light of what Reg & Wombat found. Its found on post #64, P4 I believe.
Some doubters / scrutiniers may may still ask if the results posted earlier are consistent with what Reg & Wombat found. I suggest they are. But I agree with YF that some of Wombats comments, which suggest annoyances (eg re-tuning after changing coils), are really an attribute with the QED.
Sounds like the 5.5 oz slug of lead at 22" was invisible to to the 19" / GPZ because that was a hole
in signal response
In summary, it sounds like the QED is (so far) living up to its long-touted & well-deserved reputation, here anyway. The True Believers are Vindicated! PS
: Biggold, I don't post & haven't posted elsewhere, other than as Huego or (rarely as a) guest, for many years. There is simply no need to post anywhere else.
