For one of the absolute top underwater gold prospecting metal detectors on the market, we recommend this heavy-duty model from Garrett. The extra weight was noticeable during testing, although it didn’t detract from the enjoyment of the search. There are some helpful features, such as the adjustable armrest, which means you can carry the detector in a comfortable position.
The adjustable discrimination was useful for filtering out junk materials since digging holes underwater can be time-consuming and challenging. The Pulse Induction (PI) system was ideal for working in saltwater conditions on the beach, dealing with the highly-mineralized soil with ease.
The LED indicators were useful for monitoring the signal strength, another great feature you need when working underwater. We also found the audio settings loud enough to hear faint sounds, even over the sound of smaller waves crashing on the beach, which can be a distraction on other models.
This is one of the most durable and rugged models on the market, making it perfect for rough, boggy terrain and inclement weather conditions.
