The instrument is just made of a floating sounder, which works thanks to a rechargeable 3,7V incorporated battery, whose autonomy is about 5 hours; it gets power through a cable, supplied with the product, which can be connected to any USB port. The maximum range to get wireless data is around 50 metres, while the water’s depth goes from a minimum of 40 centimetres to a maximum of 45 metres, with intervals of 10 centimetres. Compared to the other two models, this Fish Finder also gives the water’s temperature (°C or °F), so that the user can easily evaluate his fishing chances.
