hi, i have a few whites coils i no longer need. all are in very good condition and work great.the dfx 9.5" coil is $50.00 (has coil cover), the bluemax 600 is $35.00, the bluemax 950 is $40.00 (has coil cover). also have a lesche digger (looks like new) with sheath-$30.00. all prices include priority shipping.i am looking for another coil for my dfx besides the stock 9.5" that comes with it.would anyone have any real world experience on the sef or excelerator coils for the dfx? like are the depth and vdi readout accurate?or should i just stick with the whites dd coils? i am open to trades for a dd dfx coil.i am in the pittsburgh pa area. 724-889-5335. thanks!
