Congrats with the purchase of the BHTR !
Here's something I posted on another forum some days ago. :
After 28 outings with it, I have found exactly 1427 coins, 17x silver and several artifacts of various interest.
My findings are that the detector is a real multi purpose unit. With the 3 disc programs, one cane hunt very easily just after turning the unit ON, while the target disc program, with ALL notches programmable and 4 levels of iron disc (the "cousin" F4 has only 3), I can tweak it to my needs or moods.
The sensitivity is preset at 5. Very often, the detector will false at this setting, this unit is kinda "hot" ! So with sens at 4 AND the 8" standard coil, I dig coins up to 7 inches.
The 4" coil allows to run the unit "hotter", I use sens at 7 or even 8, and get good results. But be wary the recovery speed is slow (it's not an F2), and the small coil will benefit from a low sweep speed in junky areas.
With the 10" Magnum coil, the unit seems to mimic the Fisher CZ-3D in enhanced mode. Any reading above 40 will give a HIGH pitch response, While iron (low) and aluminium/small gold) retain the medium tone.
This means deep older coins will probably respond with the high pitch (bronze, brass, copper alloys, silver alloys, etc.).
The all metal mode benefits from the possibility of "on demand" GBing, and that is just a matter of pushing a knob. The GB setting also rules in the prospecting mode (P4).
This last mode, combined with the 4 or 8" coils is VERY sensitive. I am hunting the high tide mark, where most of the small jewelry lost while entering the water are lost. The darn 4" coil will get tiny gold chains and very small earring (or parts of).
Drawback of all metal and Prospecting : iron !. So it has to be used carefully, but results are impressive;
So my experience has been that the Time Ranger is a HOT thing ! Hot on silver (locks like a pit bull) in disc mode, and hot on gold in P4 mode.
As far as the ID is concerned, it is bang on up to 4". At 6, there is a small jumping show, and at 8+, for what concerns coin-sized targets, it will OVER estimate the conductivity of the target. This is normal for single frequency units.
A very jumpy ID tends to announce trash, while slight (1 or 2 numbers) OR NO variation announce goodies, with of course exceptions (round shaped, like Scaps etc).
When the "DEEP TARGET" indicator lites, just check the signal in all metal. If there is evidence of a target, try to better ID id by scrapping some soil away, or just take your chance and dig.
As a conclusion, I would say that I do not regret the purchase. I mainly hunt in target disc notching out the first three iron ranges leaving it open from iron4 to $1. Iron4 sometimes surprises me with good iron alloy objects.
It also detects, under iron 4, most of the annoying (Canada, UK, Euro cents) coins made of a steel core in a thin copper skin. Pure nickel coins are also no problems.
What surprises me is that I recently tested a very recent unit of the First Texas products line, and the newer one had many problems in coping with bottle caps, while the 10yrs older TR does not.
Hope this helps.
