I hunt often with two mates with a gpz 7 and a gp extreme. That darn extreme with a 14 coiltek elite dd smokes us sometimes.i am so surprised by the depth the extreme can get on large deep gold. It's a monster, probably a hot model, I heard some can be colder. But when he gets into the super rough ground then my 5k takes over lol. The 7k honestly has disappointed me it seems in mild ground it will put up a good fight with the gps, but you get into that mineralized cons and bedrock trends enhance and mono seems to leave them both in the dust. Hail the 5000. 😆. I <3 my discrimination to. Poor gpz.
