ran two detectors in a local park this morning,an x terra 705 and a explorer se pro.with the se pro first found $2.80aud.then i went over the same area with the xterra and found a further $8.20aud.i think the multiple frequencies are better suited to beachs.with the xterra i know what i have found by sound and numbers on the screen,where as the hit and miss smartfind left me up in the air mostly.maybe more time with it will help or it could follow the etrac out the door.emubob
