XL Pro and the 15" coil
- Thread starter landman
- Start date
I am out of town until next week and left my 15" at home, so can't test it for you right now. If nobody else jumps up, I'll test it for you next week. However, my experiences lead me to believe it would pick up a soda can at 3 feet in the air. I did find a soda can at 2 feet in the ground once.

My guess would be no more than 2.5 feet based on the following tests.

Remember 2.5 cm to an inch. This is also in European soil.
Enjoy all you cache hunters out there!

Well, here's what I found:
Settings -
Tuner - preset
Power - hot rock reject
Sig Bal - maximum
Mode - TR Disc
GEB - locked
Disc - set to extreme left (gnd rej) then turned clockwise until threshold was quiet
Coil - Blue Max 1500
First, let me say this doesn't qualify as a 'test' as such. There is no control detector, or much in the way of scientific method applied to the operation. However, the results are interesting, none-the-less. Other factors are that I wasn't using headphones, I have electrical tape over my speaker holes, and I'm about deaf in one ear (and don't hear so good out of the other!).
The first issue I encountered was the fact that the end of the metal 'S' rod is only 13 inches away from the top of the coil, and the control box is only 3 feet away from the coil. My solution was to simply adjust the Disc knob clockwise until the threshold was silent. I imagine this cut down on the detection range a bit, but since it isn't practical to detect without a rod or control box, I figured that it wasn't worth fretting over.
With the detector mounted on a wooden table, I had a tape measure laid out on the floor. I approached the coil with the aluminum can end facing the coil starting at six feet. I was able to hear an increase in threshold right around 3 feet. I approached again in the same fashion with the can perpendicular (sideways) to the coil. I heard the threshold shift at about 3.5 feet.
I wouldn't be a bit surprised if someone approaching this a bit more scientifically managed to record a threshold shift in excess of 4 feet.

That's freakin' amazing! I stand corrected said the man with orthopedic shoes!
Wonder what depth would be with an I.D. on the meter? Might be time to sell my 2 box machine and find a 15" Bluemax coil just to save the space! Great machine the XL Pro, I'm lucky enough to own one.

Well, I wouldn't run out and sell the farm just yet! 
That 15 inch coil, while impressive enough to cause coil envy among your friends, is somewhat limited in its application.
I've had mine for over a year, and haven't really used it yet. I took it out and played with it right after I got it, but didn't find anything significant. I must admit, I was pretty ignorant about how to use it too.
There are a couple places I know of that I want to get out and try it, though. My thought is that it will be best used in TR Disc, moving slow.
It would be great if someone with actual experience using the 1500 were to chime in here and tell what kind of stuff they have found and how deep, etc...

Don't worry I won't sell my spread just yet! My 2 box coil is attached to my much loved analog Master Hunter 7 which I've owned since 1990. A great manual GB detector, very versatile unit, even today.
On the large coils, 14" and up, coin sized objects start to become invisible, which is a good thing for cache hunting as small trash is ignored, especially with the Bloodhound 2 box coil on my Master Hunter 7.
My recent acquisition of the Whites XL Pro which is one of Whites finest, is one of the best relic hunters out there especially teamed up with the 15" coil. Sure is alot easier to swing than the Master Hunter.
Definitely I'll be keeping both units. Really like the XL Pro and am lucky to have her.
Your best depths achieved with the Whites Pro detectors will be in GEB/NORM or true all metal as with other detectors with this capability. Not many current detector have a true all metal mode anymore, never mind TR which is very useful for ore testing and extreme trash discrimination. All metal is how the Garretts is set for the Bloodhound 2 box configuration.
