over the next few days i`m refurbishing and soupin up some heron heads..there`ll be a few adjustments in order to combat the original faults..reckon the way they are gonna be set up now will hopefully bring these set into the 21st century..where they wont go off in the wind and also transmit via a remote system..if i`m happy with the out-come of these..these will be used by me for the rest of my carpn past-time..as some/will/might say i should`nt and i would`nt use sommat that aint reliable and put any fish in any harm..of which i can assure you i wont and may even show them in action very soon if anyones interested...ps..this needle system will be so finely tuned it `will` indicate drop backs..of course some will say in order to register drop backs i`ll need it to be very sensitive which will result in false bleeps and ever adjustments..no,this wont be the case...which if interested..will show why!!!
