The newest offering from the Scanmaster has more range, better discrimination and utilizes the same Quad Collector system offered in their “high-End” 1550 series. You will get better filtering of unwanted targets. The advanced main unit is lightweight and simple to use and there is no guesswork involved in the operator’s part. Discrimination of unwanted targets is a simple turn of the frequency knob. All controls are clearly identified so that adjustments can be made quickly. The operating range of the 1520 Pro Quad is very good with some targets being detected at over a half mile away. Includes upgraded Pelican hard-shell carry case.
