When it comes to purchasing an underwater metal detector, there are numerous factors one needs to consider. The Tesoro Sand Shark Underwater Metal Detector is among one of the high-end models that is easy and effective to use underwater. If you are a technophobe or a hobbyist, you don’t have to make any hard choices when choosing Tesoro Sand Shark Underwater Metal Detector. This six-pound beast of technology is your device. Enclosed in a waterproof casing that can go as deep as 200 feet underwater, Tesoro Sand Shark comes in an 8.5-inch and a 10.5-inch round concentric coils versions for an augmented search footprint encompassing small and large targets. This is a professional metal detecting device equipped with state-of-the-art machinery and circuitry.
Tesoro has made this underwater metal detector for enthusiasts and aficionados, putting more control into your hands. The Tesoro Sand Shark is a great pulse induction machine that allows you to go as deep underwater.
If you know your way around metal detectors, then this model should be easy to operate. In this post, we will discuss everything you need to know about the Tesoro Sand Shark Underwater Metal Detector.
The Tesoro Sand Shark goes deeper than you can imagine. The more you get familiar with the machine, the more you will have fun using it. Like other Tesoro metal detector models, the Tesoro Sand Shark incorporates two modes. However, unlike other models that are VLF (very low frequency) units, the Tesoro Sand Shark Underwater Metal Detector uses pulse induction technology, which is way better than VLF. Detectorists and hobbyists who are working underwater or at wet saltwater beaches, mostly prefer pulse induction (PI) detectors. This is because of the conditions at beaches and underwater triggers conductivity issues that a VLF unit may overlook. VLF metal detectors are highly unreliable in these areas.
With the Tesoro Sand Shark Underwater Metal Detector, you get to choose your own operating mode – the normal mode and the VCO mode.
When operating in the normal mode, it will produce a normal regular tone like any standard metal detector, as you get closer to the target. However, with VCO (voltage-controlled oscillator) mode, you will get louder, higher-pitched tone, as you get closer to the target. This is an excellent pinpointing system for treasure hunters and detectorists who prefer hunting in high-traffic regions. The best part about this underwater metal detector is that it has a fantastic search depth of 200 feet underwater. That means you can go as far as 200 feet in the water in search of treasure. However, it will require you to bush up your scuba diving skills. Lastly, it is decently priced for an underwater metal detector. Tesoro Sand Shark is Best for:
This is an advanced metal detector meant for professionals but can also cater to the hunting needs of beginners as well. Most users who have used Tesoro Sand Shark Underwater Metal Detector have only good things to say about this model. One of the users said that the machine performed well in both the locations – surface and underwater. Another user pointed out how the device behaves differently in different sand compositions – dry vs. wet. The coil may tend to chatter, which can be frustrating, but it still works if you are able to overcome those chatters and concentrate on the signal.
One user who looked like he mastered the device gave out ‘recommended settings’ advice to other users. He said that the machine works best when:
Although some complained about the threshold being tricky, the logical explanation was given that you would want to hear a low ‘buzzing or humming’ sound.
