I don't know that we'll see large improvements in depth from this or any other new machine. Why?
I wonder how much deeper or better EMI shielding can be accomplished whilst still complying with:
"This device complies with part 15 of theFCCRules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation"
Just a thought - hopefully the techos have the solutions for us?
Seen some interesting comments awhile ago from some testing that was carried out in the US with various machines from SD's through to I think they used a GPX4500. In the soil over there, which is much more benign than ours, there was no discernable or any great difference in obtainable depth. A similar test in Australia but only from SD series through to a GP3500 found similar results from memory.
Where new technology has had a perceived "depth advantage", & this is just my opinion - not technically or scientically proven by me, is all to do with improvement in the fine audio adjustments & timings that allow the operator to hear what some older machines couldn't tell them in harsher ground due to noise.
How many times have you heard/seen someone who says that they reckon their old SD2200D etc. punches as deep or deeper than their new GPX in the right conditions? I reckon their right but the new machines win out in the more harsh ground by being able to deal with that & still produce a more recognisable/audible signal due to audio & timings improvements, not outright depth improvement?
The new machines obviously also have better audio & timings for other shallower/smaller gold in harsher ground conditions too.
Despite some not wanting to speculate etc. on the new machine I think the possibilities of what could be to come are too exciting not to discuss at some level.
Imagine - a machine more capable than a GPX, better EMI shielding, more user friendly. Hmmm..... on second thoughts, maybe it's best not to have something like that in the hands of many. :lol:
