I like my Excalibur blue's with pp, and skullie's ,this set up has shed new light , deeper whisper's, and sparked an interest with the Excal's, on hearing deeper gold which i could never hear before, yesterday i was using the Nox with the 15 inch coil , and the wireless , at time's it drove me nut's with the chatter, even making adjustment's, it was the EMi from certain condo's , i might try Tony's phone's on it next hunt ,even though i am not going past ankle deep, just to see if it's the Blue Tooth interference i am getting , along with the emi from the condo's , i like both machine's, i like the lightness of the Equinox, however i probably will never submerge the head, i have a cover over it, does a nice job keeping the salt off the screen , i also had a few times the coil flipped up under the water , just ankle deep, the 15 is not recommended over the 11 in water, in my opinion, i will also say i was not using a ML lower rod, it was the Carbon Fiber Lower , with Plugger upper, both machine's have there use, happy hunting, Earl
