Hi @ faraz33, a very useful product and hunting.
The 30-degree scan angle provides a good visual field.
Can register a fish to 40m deep, not bad ...
It is good that it also gives other information about the temperature and depth of the water, of the bottom (topography of the bottom) and other information.
Automatic switch-on in contact with water and shut off 1 minute after off contact with water.
The weight is only 110 gr.Can be worn in a pocket.
The device can be used alone or in combination with other PowerVision products such as PowerEye, PowerRay and PowerDolphin.
Nice and useful product.

Good luck with hunt.
