Aquapulse 1B

[Anonymous]

Is anyone here, especially Eric, aware of any improvements or upgrades to the Aquapulse 1B unit since it came out ages ago? If so, what are the changes? Many of the salvage companies here in Florida swear by the Aquapulse and still make impressive finds with the unit but as I understand it, the cicuitry is very old and it seems to me there have been some great advances since Eric designed the unit, what, back in the early 80's?

Hi,
The Aquapulse 1B is now made by a company called Aquascan, in the UK, who also make magnetometers and other undersea survey equipment. I haven't been involved for some years, but I think it is still basically the same as my original design. A lot of thought went into the design, as it originally started as a unit for police diving teams, and had to be rugged, simple to use and reliable. It is good to know that it is still regarded as a detector that does the job that is required of it. Why change a good thing? There are many stories of manufacturers bringing out new or revamped models that are not as good as their original. Deep water detecting puts certain performance limitations on a detector, and while there are areas where one might like to see improvements, these are not always practical or possible.
Eric.
