i have the solution
[QUOTE=detectoman]hi friends i build one bfo, of six transistor, i install one coil of 40x60 cms
i have one problem, is the extreme sensitive the coil in big sensitivity volume potentiometer to ground effects
if i like my bfo great depp, actually it detect one ring of car to, 1,30 m
i can stabilizer in low sentitivity,i succes! , i have poor deep, 50 porcent, i not problem of stabilizer, only in position hig the detector is very instable o desestabilized, i install faraday shield of aluminium wrap, foil and blind copper shiel i not have good results of succes, i nedd one shield stabilizer for this bfo, i build whit my modifications
this aparatus, is low consumer of energy batery, in 9 volts
i like your help my thanks
excusme for my englisk
eureka encontre la manera de reducir el rechazo a tierra de la bobina de rastreo del bfo ., felicitenme
ahora solo falta probar si no perdio penetracion
lo logre en mucha gran medida he reducido la desestabilidad usando una estrategia de un aditamento de campo, que instale en el bobinado de rastreo del cuadro para profundidad de tamaño 65 x45 cms
sabia que habia formas de hacerlo
yo estoy feliz
i am happy
