Help for working with Wreckfinder Aquascan MC-3 magnetometer


Dec 21, 2021
Hello !

This is my first time posting on the forum and I want to apologize for my bad English first. I have been a professional diver for over 25 years. For several years I have been passionate about the search for shipwrecks in the Black Sea (I am from Bulgaria). I have bought from the best metal detectors on the market and I have a few hits that are wrecks of ships from the 17th to the 19th century. To expand the search area, I decided to buy a second hand magnetometer. In the end I got a proton magnetometer Wreckfinder Aquascan MC3 .I know it's morally outdated, but for a beginner in magnetometer research, I think it's a good choice. I read the whole manual and got some idea about working with it. But there are still a few questions for which I am asking for your help:

1. What should be the setting of „Area Tune“, for Bulgaria region, because the guide is only for the United Kingdom

2. At what distance should the lines be in meters in a parallel search for remains of cannons and anchors

3. At what depth from the bottom should the probe be when searching for cannons and anchors

Detector(s) used
A sharp eye, an AquaPulse and a finely tuned shrimp fork.
Primary Interest:
1) Call or email the folks at AquaScan. They can and will answer your 'area' question
2)According to the AquaScan manual, you would want to run 30 meter lanes to detect iron objects around 1 ton.
3)The closer to the the more the mag will pick up. Looking for cannons and anchors, I would suggest no more than 13 meters off the bottom and 6-7 meters is a better choice

My buddy who has some experience says that
1) Use 48-59 that is the magnetic zone polarization time 1 second
2)Depth no more than 10 meters from bottom
3)Each pass 15 to 20 meters max

Good luck!
