Bought a X-Terra 50 control box off of Ebay for a cheap price.To save money I modded an old Fisher S rod so the X-T control box could be mounted. I used a 3/4 inch PCV T pipe with a 1/2 inch PCV plug. The T cost 44 cents and the 1/2 plug 88 cents.The S rod assembly needs to be cut close to the handle area,which I could have grind ed closer,but played it safe.A round file will be needed to make the T and cap fit better.I'm still waiting for the Anderson 24 inch X-Terra non flex lower rod to arrive in the mail.Have two coils on the way a 9 inch concentric and the 10.5 inch DD both medium frequency.I plan on keeping the best performance coil and selling the other.
