The Tesoro Sand Shark
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:
- Gold prospecting
- Relic and coin hunting on dry land
- Scuba diving and underwater metal detecting
- Wet saltwater beach hunting
Tesoro Sand Shark Features:
- Select your Operating Mode: The Tesoro Sand Shark Underwater Metal Detector comes with two distinct operating modes – the Normal Mode and VCO Mode. When operating in the normal mode, it generates a single tone, which is helpful during beachcombing and other protracted explorations. The VCO mode, on the other hand, the threshold will generate a louder tone as the target gets closer to the coil. Most importantly, Tesoro has incorporated a microprocessor into the Sand Shark model to help you customize the underwater metal detector as per your particular requirements. Tesoro Sand Shark’s console unit comprises of a Pulse Width control that allows you to set your metal detector to the best balance of sensitivity, depth, and battery life.You can change the frequency of the Normal Mode audio by using the ‘F’ Adjust knob. Lastly, in the operation mode, the manufacturer has included a new drop-in battery compartment for easy and quick changes, allowing for uninterrupted fun.
- Advanced Digital Pulse Induction (PI) Technology: The Tesoro Sand Shark Underwater Metal Detector is first of its kind metal detector that combines the latest digital technology with the proven and celebrated Pulse Induction (PI) circuits for creating a microprocessor controller pulse induction detector for the new millennium. When it comes to hunting at the wet saltwater beaches, the pulse induction underwater metal detectors are the preferred choice as such machines can handle conductivity issues. That is, with Tesoro Sand Shark, its coil and circuitry will not see any changes due to saltwater conductivity that drives VLF (very low frequency) metal detectors crazy.
- Available in 8.5-inch and 10.5-inch Search Coil Versions: The Tesoro Sand Shark underwater metal detector comes in two search coil versions – an 8.5-inch and 10.5-inch search coils. You can choose between the two based on what’s important to you. Do you want more precise detection, or do you want to cover more search grounds? The choice is yours.
- Other Features
- Stereo Piezo Headphones – waterproof headphones hardwired into the control box
- Runs on 8 AA batteries
- Preset Ground Balance
- Operating Mode – All metal
- Sensitivity- Pulse-Width Adjust
- Waterproof
What others say about the Tesoro Sand Shark
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:
- Used in normal mode
- Volume is a little past halfway (1 o’clock)
- The pulse width is in the center position
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.
