Why multiple frequencies help
Low frequencies favor large, conductive targets; high frequencies favor small, low-conductivity ones. Running several together lets the detector hold steadier target ID in mineralized soil and wet salt sand, where single-frequency VLF detectors struggle. Many multi-frequency machines also let you pick a single frequency when the site calls for it.
Is a multi-frequency detector right for you?
If you mostly hunt one kind of ground, a well-matched single-frequency machine can do the job for less. If you move between parks, beaches and fields, one multi-frequency detector can replace two. In the hottest ground, a pulse induction detector may still reach deeper. For the beach, see our beach and water collection.
Multi-frequency on the beach
Wet salt sand is where multi-frequency detectors earn their price. They hold target ID where a single-frequency machine starts to chatter, so you can keep some discrimination while hunting the tideline. Pair one with a sand scoop and read our beach detecting tips for where the finds collect.
