I've been reading so many posts about the different detectors and am thoroughly confused about which MD to buy. I had a detector about 30 years ago when I lived in Houston. It was a cheap White's MD. I now have more time to devote to metal detecting. My budget is $300. Looking at Garrett Ace 250, BH Sharp Shooter Ultra Mag and BH Pioneer 505. I now live in Austin, TX and will do most of my looking for coins and jewelry around here (on land and along the lakes) with an occasional trip to Galveston beaches. Which of these detectors would you choose or am I missing an option? Or would you be disappointed with their performance and raise your budget to $500 and buy a better detector so you could find more stuff? Which one? Thanks for any advice you can offer. Glenn.
