I have run the 250 model and one of the newer release ace models. The newer ace model I ran actually belonged to a construction crew. They used it to find survey markers. The gent on the crew saw me detecting nearby and come over and ask me to show him more on how to use his detector.

Enjoy the video.

I started in the hobby with an Ace 350 with the stock coil. It found me a lot of decent finds. And it was much easier to master than my Fors Relic.
