Hi, i have 2 vintage metal detectors, they are both early model Garrett deepseekers. One is the first i beleive ADS deepseeker made and the other is a Master Hunter ADS 7. They are both boxed and what looks like they are new or have had very little or no use at all. I would like to keep one and sell one and am leaning on keeping the ADS 7 ? I remember buying one of these when they came out new and i paid a lot , about $700 back then, still a lot now! Which one should i keep thanks for any advice.
