HI, im a new "sand Shark" owner

Do I use VCO or Norm. in the wet sand and shallow salt water?
Thanks
That is a question YOU need to answer! I use Normal mode, but many use the Voltage Controlled Ocillator mode. Just depends which is better for your ears to understand. I like Normal, because I can hear the "Negative breaks," also called "Drop Outs," or places where the threshold sound goes silent momentarily. This can be a clue to VERY deep targets. Where did you purchase your Shark, and did the dealer offer training? Hope I can help you!
