Differences between AT Pro and AT Max

[Tony N (Michigan)]

These are the most notable differences between the AT Pro and AT Max. I didn't put in the wireless differences.

Search Modes AT Pro 6 . . . . AT Max 4

Ground Balance AT Pro: Ground Balance Manual . . . . AT MAX: Automatic, Manual

Target Id Segments AT Pro: 12 . . . . AT Max: No

Frequencies AT Pro: 15 kHz . . . . AT Max: 13.6 kHz

Search Mode Types AT Pro: All Metal, Coins, Custom, Plus (3) Pro Modes . . . . . AT Max: All Metal, Custom, Zero Discrim. Modes

What I'd like to know is: What is the difference between 6 search modes for the Pro and 4 for the Max?
What does it really mean that the Pro has 12 Target Id segments but the Max has none?
Is 13.6 kHz better for coins and depth than 15 kHz?

I notice that the Pro has "Coins" search mode but the Max has no "Coins" search mode? How does that affect a person looking for coins? Is the 13.6 kHz better for gold and fine gold on the Max?

I've never owned a Garrett but have been looking into their detector as something I can use.

Lower the khz better for high conductors,such as coins..there is a coin mode according to the pic of the at Max screen.

That's strange. Thanks for pointing that out. On Kellyco, when I do a comparison between the Pro and Max it shows no coin mode.

 

[Goldpick]

Both have 20 target ID segments as well, might be confusing 12 segments with the Ace, not the Pro.

Higher kHz is preferred for low conductors such as gold, hence why they have the AT Gold running 18kHz. 13-15kHz is a compromise frequency so you get a good response from both high and low conductors. Run a too lower frequency and a detector might be more susceptible to EMI from eletrical sources, and also lose out on sensitivity to low conductors (chains, small gold rings, buttons etc).

Depth won't be affected by frequency alone, will also depend on ground balance setup, whether discrimination is used, amount of sensitivity run, ground mineralisation, size of the coil etc. As the Max has now gained a true all-metal mode as already featured on the AT Gold, that should be the deepest mode minus any of the usual signal filtering.

It appears that Pro mode has been discontinued, and now the audio features that Pro mode offered are included in the other normal search modes (tone roll, proportional audio, pulse width modulation). So yes, less search modes, though with the same advantages that Pro mode offered the more experienced operator.

The A T Pro is a coin killer, so with a little lower frequency the Max has the Max should even be a little better. HH jim tn

I'm used to a Minelab Explorer. I know nothing about notch. I guess on the Garrett, when one notches, they are discriminating out stuff like iron nails or aluminum?

 

[Tony N (Michigan)]

Thanks so much! It's always nice to run into a knowledgeable person.

I've used mostly Minelab Explorers over the years. I'd like to try the Max but am just, well, I just don't know. Have you ever used an Explorer and if so, can you explain the difference the Max would have over the Explorer?
I've been biting at the bit on this Max.

 

[Welgund]

Explorer is a multiple frequency machine. At Max is a single frequency. Recovery speed of the Max is much faster than the Explorer. Explorer is probably deeper on high conductors. Max is fully waterproof to 10ft. In old iron infested sites the Max should perform better do to faster recovery speed. Should know more I nce it's released and people start testing it.

Do you know if the Pro or Max need to continue having a pretty quick sweep speed even when a coin is found among trash or can one sweep really slowly and still maintain a target hit?

 

[John-Edmonton]

You can notch out any conductive segment ie pull tabs, iron, coins without losing any depth, unlike typical discrimination settings where, as you advance the discrimination, you continue to lose depth. On The Garrett notching system, the only the audio is tuned out.

 

[John-Edmonton]

The AT Pro has a moderate swing speed, much faster then Minelab multi frequency machines. One should never swing too fast as you may audibly miss some of the high tones in trash.You will be able to analyse more targets per hour with a AT Pro then multi frequency machines.

That's cool to know about the notching!
Since we are on the subject of Explorer and Pro, do you know if the depths of both are about equal?
If they are about equal, then it would seem the Pro has at least one advantage in that one can cover more area in the same amount of time.

 

[Southwind]

I thought I saw 40 target segments just in the iron range?

Being one who has never used a detector like this, could you explain to me how one would use those 40 target segments in the iron range?

 

[John-Edmonton]

That would depend on the soil conditions.

Suppose the soil is exactly the same. Would the Pro be just as deep as the Explorer?

 

[basstrackerman]

In absolutely ideal conditions then maybe. Understand that depth is only attained if the conditions allow.. If an older slower machine that was deep as China met with can slaw, rusty nails, tin, hot rock, coal, or anything leaves a lot in the ground for the next guy with a faster machine that has a great coil design... Too many variables to determine depth of a machine.. Some detectors have better see through ability than others... Some of my best finds we're with an ace 250 and a tesoro silver umax...

AT pro and AT max both have automatic as well as manual ground balance.

The AT max looks to have atleast the same number of target ID segments ad the pro.

The AT max having a little lower operating frequency than the pro , may actually serve a little better in the depth category because of the lower frequency. Generally lower frequency is better for depth , while higher frequency better for gold.
