I am fitting active Sonar from a wireless fish-finder to the Typhoon. works on 3v coin battery. Antennae must be above water to receive a signal. Useful for checking depth and for obstuctions before diving. Also just for fun
This is the sonar transduser. The hull does not interfere with the signal.
the extended tail looks much better. Still another does question have to that is made these brass photo etched grills themselves, or bought? If bought, where one gets these?
