I like it, has brought the AT Pro up to date with its current competitors with many long overdue features and changes in respect to performance. The tones sound much crisper than the outgoing Pro, something that would particularly suit myself - can't say I was too enamored with the original tones.
Expanded ground balance range will be a welcome sight for those wanting to beach detect (ground balance to salt) or prospect, plus the added true all-metal mode and threshold are other essentials for prospecting. The All-metal iron audio will make for easier detecting on say goldfields type sites where iron junk is prevalent, whilst still retaining the max depth capabiity of all-metal.
The backlighting was well overdue, and unfortunately one of the reasons why I never considered the AT Pro in the past.
It is good to see that the wireless headphones are included in the package, and are not a seperate option - does away with using those fiddly 2 pin connectors is an added bonus, that is unless using the waterproof headphones.
Whether the increase in transmit power will equate to real world depth gains, that remains to be seen - guess we have to wait till customers get their hands on it.
What are the negatives, the iron audio really needs a volume control rather than having it loudly grunting away in the background -- other brands/models costing less have that feature, so should this detector. The S-bend shaft should have had a complete overhaul to improve the ergonomics and balance of the nose heavy AT Pro (as with all the Ace series as well) - take a look at the Fisher F75 and Teknetics G2 to see what can be achieved with a decent shaft design. I understand that the epoxy filled coils need to be reasonably heavy for water hunting, though some lightweight coil options would be great for dry land detecting, and also improve the balance whilst reducing fatigue.
All up a pretty good "evolution" of the AT series, sure it doesn't bring anything new or innovative to the table (could see that coming after the Ace 400 release), I'm sure Garrett will still sell squillions of the things having such a large and loyal customer base. I reckon I would definitely prefer the Max over the issue plagued Whites MX Sport, its main competitor being waterproof. If only dry land/beach hunting, maybe not so much so with the release of the selectable frequency and feature packed Nokta Impact sitting smack bang in the same price range. Now to see what our crap exchange rate does for the Oz pricing, it's pretty quiet on Garrett Australia - not a mention of the AT Max. :|
