Rick K - First Member Posted June 15, 2020 Share Posted June 15, 2020 The Impulse AQ Limited sales are restricted to the US and CAnada. The follow-on AQ will have at least some international distribution. 1 Link to comment https://www.detectorprospector.com/topic/12848-fisher-impulse-aq-limited-first-impression/page/5/#findComment-127914 Share on other sites More sharing options...

Is it low mineralized , is it salted ? Just to know your conditions of testing .. I saw somewhere in the forum that the AQ would be deeper on wet salt beach than on low mineralized dry ground , this is why I ask the question … Thx Link to comment https://www.detectorprospector.com/topic/12848-fisher-impulse-aq-limited-first-impression/page/5/#findComment-127936 Share on other sites More sharing options...
Steve Herschbach Posted June 15, 2020 Author Share Posted June 15, 2020 I will not be hunting saltwater with the Impulse in the near future but instead local freshwater lakes. The coast is farther than I want to drive for now. Lake Tahoe is a freshwater lake, with beaches made up from material derived from granitic rock. It is a very large lake, with 72 miles of shoreline. Most beaches are pebble beaches. Sand Harbor is a one of the rare sandy beaches on the lake. The sand is heavily laced with magnetite that will greatly inhibit or overload and shut down most VLF detectors. Metamorphic and volcanic hot rocks are also fairly common on the lake. https://www.earthmagazine.org/article/travels-geology-lake-tahoe-jewel-sierra-nevada Black sand (magnetite) layers exposed on beach Closeup of magnetite black sand. Note dark gun metal granular nature of the sand. Highly magnetic. This is a magnet that has been dropped onto the sand and picked back up - a golf ball size lump of magnetite. Most of the soils in my area have a high magnetic component, and most VLF detectors get roughly 60% of the depth normally quoted on most U.S. forums. A ten inch dime here is a bit of a joke... more like 5-6 inches. This beach is particularly bad, and will send the Equinox into almost continuous Beach overload mode. Other modes have to have sensitivity drastically reduced or the machine basically shuts down. Difficult Areas – Black SandSome beaches contain black sand, which has high natural iron content and is often magnetic. This causes continuous false ferrous detections, making normal beach detecting impossible. Beach Mode automatically senses black sand and reduces the transmit power to ensure that targets can still be detected without overloading occurring. When black sand is sensed, the Beach Overload Indicator will appear on the LCD. When this icon disappears, full transmit power automatically resumes. 3 4 Link to comment https://www.detectorprospector.com/topic/12848-fisher-impulse-aq-limited-first-impression/page/5/#findComment-127943 Share on other sites More sharing options...
Badger-NH Posted June 15, 2020 Share Posted June 15, 2020 13 hours ago, Steve Herschbach said: Short story is this is the wader version, to be followed by a dive version with drop in batteries and a depth rating up to and probably exceeding 10 feet. Etc snip Got it. I didn't know the dive version might be available so soon. Not that I want the dive version. The only advantage to that for me would be the battery. I am psyched to get the Limited at a much lower price. ? Another advantage of getting the Limited is that Fisher is no doubt going to make sure that each of these units are flawlessly assembled, because these are the detectors that will be generating future sales of the mass produced models. . 4 Link to comment https://www.detectorprospector.com/topic/12848-fisher-impulse-aq-limited-first-impression/page/5/#findComment-127952 Share on other sites More sharing options...
