I'm a long time Explorer II user and I've done very well with,never felt outclassed by any machine including Etracs.This year I hunted with several CTX users and for the first time really could not compete with a couple of the CTX users but a couple I could.They seemed to use different setups for their machines which produced very varied results,some could not pick up good signals picked up by the A class users .neither could I.It looks like how the unit is set up makes a huge difference in performance in trashy park setting.It seems to me,using a real simple machine to set up in an Explorer,that CTX is rather complex and like the Whites DFX,you better get it right or performance can really suffer.I am seriously considering a CTX but I'm concerned that I would be spending many hours tweaking settings and modes to get it perform for my hunting.I would appreciate any users insights.
