If you enjoy looking for metal treasures then you know that underwater is where the gold is. Thousands of people lose metal valuables in water bodies every day. In case you have been wondering about how to start under water treasure hunting relax! We have got you covered. Here are seven easy steps for using a metal detector underwater. If you follow these directions you will be a Pro before you know it.
Seven easy steps for using a metal detector underwater
1. Select the right metal detector
The decision should be based on the type of water body i.e. fresh or salty water.
For fresh water you should use a Very Low Frequency (VLF) detector. These have great sensitivity and can detect even thin metals like rings and bracelets. Because of their great discriminating power they are great at sieving through junk hence saving you time and energy.
Pulse Induction (PI) detectors are ideal for salty water. They are not affected by wet sand and ground mineralization. They are not as sensitive as VLF Detectors and so you will spend some time sorting treasure from trash
2. Get the right accessories
These should include waterproof headphones. They help you focus on deep targets by blocking out external noises. These usually come with the metal detector. You should also invest in the following: a carry bag for the safe transportation of your metal detector, a trowel and at least one metal detector sand scoop. The last two greatly speed up your recovery time.
3. Adjust your settings
It is important for you to select the settings that are usable underwater depending on how far below water you intend to go and what type of treasure you are looking for. To set the right frequency you should test it on the kind of target you are looking for. This will ensure that you do not miss the frequency of small items like coins.
Your working style is very important in underwater metal detecting. You should work in slow consistent motions. To make this easier for you, come up with an imaginary path that you are following. Cover it exhaustively before moving to the next path.
5. Plan your course
It is important to come up with a good schedule for your metal detecting activity. This should include the time and location. When selecting the location consider places where a lot of people have visited recently. People’s valuables simply slip of their moisturized bodies when they get into the water. So the greater the traffic, the greater your chances of finding valuable objects. Summer is ideal since everyone goes to the beach. Also plan to work during the day as it is easy to separate valuables from junk when you have enough light.
6. Cooperate with Mother Nature
The success of underwater metal detecting activities is almost entirely influenced by nature so you need to understand it. Here are a couple of pointers that will help you along the way. Start working slightly before low tide this will give you the best results as most metal is found in the deeper levels of the ocean. Use the currents to lead you to high potential sand. Go to areas where you detect water movements as a lot of sand will be carried there by the current. Last and most important; is the ocean often carries materials of the same weight and keeps them together in sand pockets. If you come across a couple of metal coins buried together keep digging you are likely to get something even more valuable like a ring buried underneath.
7. Take care of your underwater metal detector
This goes without saying. You should clean it immediately you finish using it. Use clean water to clean your detector. This will prevent erosion from the salty water in case it was exposed to it. When working in salty water it is also crucial that salty water does not get into the control box. Once it is clean and dry return it into the carrier bag.
When treasure hunting it is also important to note where you find valuable items. You may find something else there if you go back.
