I bought my Ace 350 plus I paid the $35 extra for the Package #2 option from them not too long ago this year.
I can tell you that most of the stuff they include with prices of each is way over inflated.
Here's the webpage:
Garrett Ace 350 Metal Detector For Sale - Kellyco Metal Detectors
Ok for example they have those Dollar store gloves retail value at $19.95
The 2 pocket coin pouch for $9.95 It is cheap vinal. Home Depot or Lowes sells sturdy cloth nail poiches for like $2.00
The same type and brand (Fiscars) composit digger they have listed for $7.95 can be had at Walmart for $3.95
The CD you might look at once it is mostly generic common information that you can easily find 10X more info on this forum.
The $ 6.95 sheath is vinal and won't last long either.
The headphones already come packaged with all the Ace 350's so it is not an extra.
the $39.95 backpack is basic and thin vinal, Dollar Store quality.
The Sawtooth gator Digger is ok if you have never used a digger before. Put a copper pipe cap on under the grip so the grip doesn't wear through and give you a big blister like it did to me after about 4 hours of use in dry dirt.
The Metal Detector carry bag is decent.
I also got the BOGO offer and that included the Bounty Hunter pinpointer. Which will only detect coins an inch away.
In conclusion the package has all the basic equiptment to get you started for the price you pay for it but most of them are cheaply made and will wear out quickly or be of no use to you at all.
I wound up after a short time of using them getting a Lesche digger and a Garrett Propointer.
I also wound up buying the smaller 5x8 DD coil for trash areas in parks ect.
If I had to do all over again to save money, I would have ordered the Ace 350 2 Coil package that also comes with the 2 coil covers. (you definitely want them!) With none of the accessories they have to offer. If you call and ask, it is a cheaper price than the internet price with the options included. If they won't do it there are plenty of the forum sponsors that are retailers that will sell you just the unit.
I would have also ordered the Lesche digger and the Garrett Propointer.
Then I would have gone to Lowes or Home Depot or Walmart and picked up the other incidentals like gloves, finds pouch, ect.
All the metal detecting information you need is better and free on this forum.
Good Luck with your purchase and happy hunting.
