The Garrett ace 150 independent field test I am amazed how easy
it is to operate even for a complete novice.
ace field test
By a complete novice
Having watched another re
run of Hidden Treasures on sky Andrew my son asked if we could
have a go at metal detecting, this was not the first time he had
shown interest, in fact with so many repeats of Time Team on the
telly who could not resist a chance of finding lost treasure. With
a little internet research we decided to go for the Garrett
treasure ace 150.
Garrett Ace 150 controls
looking at the Garrett Ace 150
novices like Andrew and myself the Ace 150 looked a little
complicated, once explained the functions are quite simple.
Assembling the machine was really quite easy, my only advice
would be to watch out for the coil connector it can only fit into
the control box one way so take care not to force it.
Gently pressing the power button awakens the machine from it's
slumber, it quickly runs through a check sequence and settles
down. During the check sequence a battery symbol appears with a
cross in it then disappears, we automatically assumed the
battery's were flat, so installed another set, but still got the
I called Gary in a panic, he said don't worry explaining, the
Ace 150 has no battery condition meter, this feature was only for the Ace 250, the icon is in the software.
Returning back to the machine we investigated the Mode button,
there are 3 different search options available, all
metal,jewelry,and coins, by pressing the button once it switched
to the next mode, it worked on a continuous rota so if I pressed
the button 3 times it would scroll through the other 2 search
options and return to the original position.
Testing at home with some old pennies, modern coinage and a ring
pull we soon got a feel to what the different search modes
Position 1 All metal : This picked up every target
including Iron, however the Iron gave a much lower tone than any
other target. Small coins gave a short clear tone and large coins
gave a bell tone. I guess this is what's known as tone ID.
Position 2 Jewellery : The Iron was now rejected, it gave
no signal at all, even when a large pair of pliers was passed
over the search head. All coinage and large pieces of foil were
Position 3 Coins : Ring pulls, Iron, foil, and some modern
coins like a 20p, 10p, and 50p's were now rejected. In the coin
search mode the Ace 150 easily picked up most pre-decimal
coinage, sixpences, pennies, half crowns and modern £1,
Our first trip was to a local riverbank where we had seen an old
chap metal detecting whilst walking our dogs, we assumed it was a
suitable place to start, feeling confident about the new machine
and hoping to find something interesting. Andrew had the first go
while I walked along side with the spade, I kept commenting on
his side to side sweep, it appeared to be a long way above the
grass and it raised even higher at the end of each pass, I didn't
realise until I had a go myself that how difficult it was to make
an even sweep with no upward movement, with a little more
concentration and a slower walking pace our technique started to
The first signal we heard was a low tone, very strong
and precise, when we dug the sound it was large square nail. In
fact there were quite a few low sounds some we investigated but
all turned out to be Iron. We agreed to try the machine in the
jewellery setting, the machine became quieter and the low tone
had disappeared altogether. We were suddenly alerted to a sound
we had recognised from our testing at home, it could only be
described as bell type sound, a dding-dding every time the
machine swept over the area.
The depth indicator had illuminated
the 6" sector so we dug approx 6 inches down and recovered a
Victorian penny the date was visible 1868, our first real metal
detecting find fantastic!. This penny was not to be the only one
as we had a further 6 in the space of half hour. Ring pulls were
a pain we dug a handful just for the experience ,they gave a
different sound, it was a much shorter tone, plus the indicator
block on the bar graph fell directly under the pull tab marker at
the same time the machine gave a bleep.
Another way of checking
to see if the target was a ring pull was to press the mode
button once, switching the machine from jewellery to the coin
setting and checking again, if it was a ring pull the target
would be eliminated, however would I be ignoring a gold ring as
the graph indicates some gold will also fall under the ring pull
One particular signal gave a short tone, the bar graph could not
make it's mind up, it bounced between the pull tab and the ring
marker. The depth indicator displayed the full 6 inches, we dug
down to find a near perfect sixpence.
We were to busy admiring our first silver coin and didn't notice
the stranger closing up on us until the last minute, we looked up
as he raised a spade to say it's ok I'm friendly, in his other
hand was a metal detector, it was the old chap we had seen here
in the past, he looked at Andrews machine and commented how
important it looked, then started to tell us about the old days
and how they used broom sticks with transistor radio's strapped
to them, which I'm sure is quite interesting in the pub, but not
when you have just unearthed your first silver coin and eager to
find the other 50 buried next to it.
Eventually we parted
company and started detecting again, then we heard a shout "oiy",
it was the old boy again," come and try this one" he said
sweeping his coil on the grass. Politely we obliged, there was a
dent in the grass where he had dug his heel in to mark the spot,
I tried our machine over it and got no reaction ,"nothing there
sorry" I replied, and tried again "that's it, no back a
bit,no,yes,there" the old boy was wittering on, "try it in all
metal" he said, its deeper. Ok so I tried it in all metal and the
ace gave a low tone with the bar graph pointing to Iron. "I think
it's Iron" I said to the man, he shook his head saying something
like if that's iron he would eat his underpants and proceeded to
dig, he finally unearthed his trophy half a plough shear, silence
fell, only to be broken by the sound of rain falling on the
water, we parted company for the second time and headed for the
trees, while our friend turned on his heels and marched towards
the car parking area.
We waited for a while for
the rain to stop and searched a little longer even more confident
with the Garrett, our search technique had without a doubt
improved, this was reflecting in the amount of targets located on
the way back to the car, almost re-tracing our original
Here are the best finds in one afternoon (our first outing) on the

gary i got an ace150 from mike longfield 4 my young son i am not new to the game i
have 4 detectors my self ie a gold max a cortes and two fishers well right back
to the ace 150 i got my lad it as it was nice and light 4 him well we got home
and went out with it we went to a field i have been doing 4 15yrs now it as
well been done but the odd thing comes up now and then well we had a play with
its modes and found the best mode was the jewellery and sensitivity on 3 this
setting looked and sounded like the best with the tests we did with it well we
played so we set off 4 real looking we got some lead bits can pulls but nothing
much in the line we wanted so we went home after my tea i went out on my own
with it i put it in the same setting as b 4 and off i went in the same field
after about 35 min i got a ding i looked at the meter it was on p/tab as i did
not get a ding 4 a long time i dug it up to find a hammered coin looking at me in
the dirt that was the first one i ever had on that field i was thinking all the
times i done it with what i thought was good detectors and i got what i thought
was a toy and got this hammered coin in my hand well i was on a high now so off
i went back to my job in hand i only walked 6 feet and got a another ping this
time it was showing it was a coin so i dug down and what a shock i had it was a
another hammered coin and in good nick at that i looked at it and i could see
james 1 head on it it was a james 1 shilling by the time i could get my head
round it all it was going dark so i went home when i got in i looked at the
first coin it was a Elizabeth well if anyone says a ace 150 is up to the job i
say yes i think it dos the job in hand well i will not say its a toy again as
its not one its performance fooled me i even put ace 150 in my name as you can
see and proud thanks hope it helps you out.
love the website so i thought i'd send you a review of my latest purchase, the Garrett ace 150
i have been using an old c scope for a while now and after watching some video clips of finds on you tube decided that I would invest in a newer machine. I considered buying one from ebay for a while but in the end the reassurance of being able to have contact with the dealer if i had any problems proved to much and i eventually went to leisure promotions in Newbury. looking around the shop I wished i had more money! I settled on the Garrett ace 150 as it fell into my price range and appeared to be versatile and lightweight.
rushing home I couldn't wait to get it out of the box, assembly was easy and when complete the unit felt robust. I quick viewing of the included dvd gave me an overview of the basic functionality of the 150. then out to the fields!
I usually detect beaches and sports fields in the UK coinshooting as they say, I've never found anything old so i just look for modern coins. cycling through the Garrett's modes I found all metal far to noisy, with lots of iron in the ground down here i couldn't walk two steps without it going off with a deep tone. I switched to jewellery and that setting worked much better, I considered the coins mode but who wants to miss that elusive first bit of gold! well how did it perform I hear you ask, for modern British coinage 10's 20's £1 it usually jumps between pull tab and ring settings with a medium tone, for bronze coins like pennies and 2p it responds with a nice bell twin tone. the ace 150 really loves 2ps by the way, they are by far the most common coin I find.
Other finds with this model have included lots of bullets, pieces of lead, musket balls, two bronze rings, a nice 1963 half crown, a couple of shillings, a three penny bit and best of all a William III half penny dated 1699 found 4 inches down and a William III penny found at 6 inches.
Issues with the Garrett 150
This model doesn't have a pinpoint feature which makes identifying the exact place of the find difficult. even following the instructional videos method of sweeping an X still left me digging quite a large hole, with the target often being off centre from where the centre of the x fell. another issue is the volume of the unit, damn its loud lol, with headphones its really loud a volume pot would be nice.
All in all its a good starter model, I wish I would have waited though and bought the 250 as the pinpoint feature would be worth its weight in earth extracted lol.
