Extreeme-Booster range extender for Deeper PRO+/CHIRP+/START+/PRO fishfinder 400m+

I am pleased to inform you that I have realized my idea for a proprietary device increasing the range in fishfinders. Extreme-Booster, since this is the one in question, was built by me from scratch (it is not a modification of a router or other such device). The entire PCB with the housing and power section has been designed from scratch.
Basic functionalities:
Non-invasive range increase thanks to Extreme-Booster even above 400m
The 4.5V - 17V input power supply allows the connection of any type of battery used in the bait boat, and the XT60 plug ensures a stable connection with the power plug.
Designed from the ground up, the PCB, power section and housing allow us to offer a complementary product
Works with all fishfinders on the market with built-in WiFi, for example: Deeper, Lowrance, Raymarine, Garmin ...
The possibility of direct installation in any, even in the smallest boat, dimensions of the device in the housing are: 12cm x 4cm x 3cm. On the shore, all you need is a phone or a tablet!
The possibility of extending the functionality with GPS, for fishfinders that do not have a built-in GPS, e.g. Dragonfly 4 PRO allows, thanks to embedded GPS module, to develop bathymetric maps, e.g. in the Navionics application.
Detachable antennas enable the installation anywhere on the boat using the RP-SMA cables
Minimal power consumption of about 1.5A - 3.3V
Something is interfering the frequency on the boat's?? now it's not a problem, full freedom to choose the broadcasting channel in the range 1-11 (always set by default at 11)
Completely new software designed for this system allows for efficient and failure-free operation
Price: 200EUR + shipping to EU Countries 25 EUR
