50% More Power To The Manticore Coil?

[Cal_Cobra]

I've seen a few comments that the 50% power increase only applies to single frequencies, but NASA Tom said no, it's across the board, single frequencies and SMF ?

Tx guage wire also effects depth, it isn't always just about voltage.

I still don't know why companies push such big coils, other than for clean plowed fields or sanded beaches large coils aren't all that necessary and can be very counter productive. More prone to EMI, heavier to swing, harder to separate around high trash areas.....

Majority of finds are well under the 10" mark and in parks expecially with so many people detecting now most the finds are near the surface and are fresh drops.

Not where I live, I'd say the complete opposite is true, the good old coins are very deep, the deeper a detector can go the better, anything less than the depth of my Carrot is usually the bad stuff, more recent drops, the deeper stuff is the good old coins.  Jewellery is anywhere obviously depending on how long ago it was lost.

Big coils are fantastic for me, the bigger the better and they do go deeper than the smaller coils.  The CTX 17x13" is my current favourite deep coin finding coil.

We don't know what we don't know right? 

At one particular site for years my hunt partner and I assumed that targets weren't deep, because in the beginning we were digging plenty of targets that were not deep.  Once those easier to detect targets dried up, I started investigating anything that made a beep.  After digging a measured 10" deep two reale, a 10" deep copper fractional reale (a rare one), a seated dime cache that was right at the 10" mark under an inch thick layer of scorched earth, and a solo seated dime that was 10-11" deep, I put that assumption to rest.  I think what we generally observe is that 10" is at the edge of the VLF detection capabilities before a machine calls the target iron IF it detects it at all.  After digging the aforementioned deep targets, I can only surmise that there is another layer of targets that my current arsenal simply cannot see.  

Would I want to dig 15" holes at a park? Nope.  Not because I don't believe there's targets potentially that deep, but the optics of digging such a hole in public has it's own ramifications.  I've detected several old park scrapes in San Francisco, you'd be surprised what we find after they scrape off 12" of dirt, there's plenty of old targets there like this 1916D key date Mercury dime I dug:

Deepest coins I dug were where dirt was moved and not from natural sinking from worm activity etc. I dug a reale at 12", couple silver dimes at more than 12". Majority of large cents here are in the 10" mark or less.

Big problem running large coils here is we have a lot of old iron bits and magnetite so bigger the coil the more it gets smothered. I'm sure other parts of the country the case is different.

Well it could if they are series but my money says they are parallel and still 3.7v. That would give it more current, the work horse of the battery.

I agree.

You generally want to use one cell instead of two, as that halves the chances for a bad cell to make the device inoperable. So why would Minelab go from one cell to two? Higher voltage requirements is one possibility, but like PimentoUK said, that's not a compelling reason as you can step up or down voltages fairly easily. So providing additional current is probably it...and my guess it's not that the Manticore pulls that much juice over extended periods of time. Rather, it's that the Manticore might have relatively high current draw at peak moments and Minelab engineers felt they could improve cell life by reducing the current draw on the cells.

I'm all about the depth, if it can give me 50% (More) power in the saltwater and can match the AQ I'll buy one, but if that 50% is like turning your high beams on in a snow storm ..it's just another steak on the grill..

That is a perfect analogy and exactly what happens here around in land. I do much better with smaller and more importantly eliptical coils over round coils. Not only do they run quieter, they have more accurate ground balancing and can separate much better.

NASA Tom stated that the Manticore would blow an Equinox coil right quick.

It makes sense that Minelab would want a comprehensive/whole system power system to boost the TX signal & run the next generation signal processing. If you want Horsepower you have to feed the horses. All this speculation is fun & there are many smart people here to learn from but it is still early in the learning curve.  I do see a need for the unit to be able to run an auxiliary power source.
