Do you only use one device? It’s a common question, and the answer is almost always no. Detector, pinpointer, and underwater coil have different functions, and using just one of them is like trying to fix a car with a single tool.
The metal detector: the broad scan
It is the main equipment, responsible for covering large areas of sand, shallow water, or grass in search of any metal signal. A good multi-frequency detector can differentiate types of metal and ignore much of the common beach trash, like bottle caps and staples, but it indicates an approximate area, not the exact point.
The pinpointer: the centimeter precision
After the detector points to an area with a signal, the pinpointer comes into action. It is a smaller device, shaped like a wand, that locates the object within a radius of a few centimeters, avoiding the need to dig a large hole or turn over more sand than necessary. It makes the difference between removing a shovel full of sand or just a handful.
The underwater coil: searching safely in the water
When the loss occurs in the surf or at greater depths, a coil designed for submersion comes into play, attached to a waterproof detector. It allows maintaining sensitivity even with moving saltwater, something that a common land device cannot do without constantly giving false signals.
Why different terrains require different combinations
Dry beach and sand court
More predictable terrain, allowing for faster scans with the main detector, reserving the pinpointer only for the final stage. It is the most common scenario described in searches on beach volleyball and footvolley courts.
In the water
Requires the underwater coil and specific sensitivity adjustments, as salinity and wave movement increase interference. The tide calculation explained in how the time of loss changes the search strategy also directly influences which depth and which section to prioritize.
Lawns and gardens
More stable terrain, with less interference from salt and moisture, generally allows for locating the signal more quickly, but requires extra care not to damage the grass during excavation.
The equipment alone won’t solve it
Having the three right pieces of equipment helps, but it doesn’t replace the search method. Many cases resolved after others had already given up were not due to a more expensive device, but because of how the area was read before turning on any detector.
No equipment finds everything
Even with the right detector, pinpointer, and coil, there are physical limits: pieces with little metallic mass, like thin chains, small link bracelets, and delicate earrings, give weak responses, and depth, soil, and seawater also influence. That’s why we don’t promise that a device, no matter how good, will find any piece. Read about chains, necklaces, and bracelets and the technical limitations of the service.
What equipment does Dr. Detector use
We work with waterproof multi-frequency detectors, precision pinpointers, and coils designed for underwater searches, choosing the combination according to the terrain and depth described by each client before the search begins. If you are in the middle of a search right now, talk to a detectorist near you and tell them the exact terrain where the object was lost, so we can arrive with the right equipment.
Passo a passo imediato: perdeu uma joia na praia ou na água?
Faça isto agora, nesta ordem, antes de procurar por conta própria:
- Pare e marque o ponto: isole a área onde o objeto deve ter caído e fotografe referências fixas ao redor (poste, quiosque, posto de guarda-vidas, pedra, árvore).
- Não cave e não deixe muita gente pisar ou revirar a areia: isso afunda e espalha o objeto e atrapalha o detector.
- Anote o horário da perda e se foi na areia seca, na areia molhada ou na água: a maré muda o terreno em poucas horas.
- Chame logo um detectorista profissional credenciado da rede Dr. Detector na sua região: quanto antes a busca começa, maiores as chances (sem garantia de resultado). Pedir um detectorista agora.
