Steve,
thanx for your input.
There is absolutely nothing wrong to say a certain machine hits certain niches, but possibly not others. This has been true of all detectors since the dawn of time. No harm in that.
Example: I have machines that see through and around iron great! But they lack depth. Then I have other units that kick b*tt on depth! But they mask easily in iron. In this example, if the proponent of the first machine were to get his feathers ruffled when someone else said it lacked depth, is overlooking the bigger picture, that his machine kicks b*tt in iron riddled spots! Every machine has its pros and cons.
One thing is for sure: There has never been any pulse machine ever, that could be used for coin/relic sites, especially if they were nail ridden, junky, etc... It would just have been too punishing. Now at least, there IS a pulse that could be made to do it. That is a big step!
One thing for anyone to remember, if they are looking at any new machine, for deep coins, is that there is whole issue of sounds and tones to interpret. So for example: An Explorer ace would have no trouble discerning the tooty-fluty sound that tells him "this is deep silver/copper" right? BUT to the un-initiated person, they might hear that SAME sound, and dismiss it as nothing but background flutters. It is entirely possible that it will be the same with the TDI: Someone trying it over flagged targets, might dismiss whatever signal they can eak out over the flagged target, as simply non-distinguishable from all the other chirps and flutters. But to a proficient user of that machine, a certain sound or tone might be totally tell-tale! So as I get the chance to try this in the field, I will be totally aware of this psychology, and look for any tone/sounds at all, as something that could be used to push the limits of the machine. Whether or not I initially can tell those sounds from the rest of the symphony or not
