First decide what you want to find
A river beginner looking for small alluvial flakes usually needs a pan before a detector. A detector responds to a metal target; it does not tell you that an entire gravel bar contains recoverable fine gold. Decide whether your task is nugget searching, general metal detecting or learning panning.
Compare the whole setup
Ask a dealer to demonstrate ground balancing, a repeatable sweep and recovery on terrain similar to your intended trip. Manufacturer manuals describe modes and waterproof limits; read the exact model manual, not a generic retailer headline. Waterproof coils do not necessarily mean waterproof control boxes.
Weight, coil choice, battery availability, headphones, weather protection and a service route affect whether you will use the machine. Compare the total working kit rather than an advertised body-only price. No specific model here has been independently field tested by Paystreak.
Do not buy a depth claim
Target size, shape, orientation, mineralisation, interference and settings all change detection. There is no useful universal maximum depth for a gold detector. Ask what target and soil a demonstration used. A clean test garden and naturally mineralised ground are different situations.
Learn a controlled sweep
Start with the manufacturer setup procedure. Choose a small permitted patch and cover it in overlapping lanes with a consistent coil height. Recheck a repeatable signal from a second direction. Change one setting at a time and record why. Do not raise sensitivity until the machine is unusably noisy.
Permission comes before recovery
In NZ, check the designated area and its particular method conditions. A detector listed among possible hand tools does not waive heritage, vegetation or active-bed restrictions. In Victoria, use the current Miner’s Right and permitted-area guidance. Do not transfer one country’s rules to another.
Try this before the next step.
Write a one-page hire brief: target, country, permitted site, total carry weight, operating time, budget including accessories, and three questions for the demonstrator.
