The term is "Value" and without a doubt it is the Ace 250. This is why it is the most popular entry level detector. Garrett is an awesome family owned company and goes to great efforts in keeping a happy customer. Think about it, you buy an Ace 250 for about $200 and can most likely get a full return on your investment within the first year. Yeah you can get luck with any machine but realistically no other detector does that constantly. Many Ace 250 owners love them.
I tried one for about 5 minutes and didn't like it, but I was used to my Minelab so 5 minutes wasn't a fair test. Also my detector was 4 times the cost so that too wasn't fair either.
Can I kick the living crap out of the Ace 250 with my Minelab? Absolutely but I won't do it 4 to 1. In some instances the person using an Ace 250 might even out detect me.
Knowing all this at the start would I buy an Ace 250 instead of my first Minelab? If I wasn't sure I wouldn't stay with the hobby. Over time the Minelab would turn out to be a better value but that could take up to 3 years and if after 3-4 months I decided detecting wasn't for me I would be out a lot of cash due to the big price drop of a used minelab vs a new one.
But I know people that have been in the hobby for years and use an Ace250. They have had many opportunities to buy a more expensive machine but they decided to buy another Ace 250 so hard to say. I can tell you though, if it wasn't for beach detecting I probably wouldn't have bought a Minelab but instead an Ace 250 a Teknetics or a Fisher F75
