Hoping to obtain deeper depth is over hunted parks, I decided to purchase a 15", 3khz coil for my 705. ------------According to an article I found on the net, (put out by Minelab), the Coiltek line has been replaced by the Minelab version. -----Same coil, same size, same weight, same specs, one is black, the other is orange. ---- The Minelab 15", 3khz coil was $190----the Coiltek version of the same coil is about $235-$285, depending on where you buy it. -----------am I missing something? ---- Thanks!
