From what I have read the Sov. does not like modern Canadian coins since the are basically made of plated steel. Sov. are made to null out on iron and steel.
The Excalibur is based on circuitry similar to the Sov. that's why it's considered a waterproofed Sov.
Canadian coins are going to give mixed signals. It took several weeks of hunting a soccer field to figure out why I wasn't find many coins.
The signals I considered junk in the US were actually Canadian coins, different year periods gave different sounds, double blips, whooppy sounds,
one way sounds...etc. Once I decided to dig the junk sounds, I started finding coins. Went back over the areas I detected and came home with piles of them.
I learned the sounds of CA coins.....and still dug pulltabs etc. You need to also cut back on the disc. setting.
If your buying the Excalibur, I wouldn't be wasting my time on CA coinage, your going to be after gold and silver jewelry, old silver coins. You will get them in
Canada. You will have no problem picking up the Loonies and Toonies with any detector. They tend to be found almost as often as you would find a quarter in the US.
The Loonies and Toonies our best friend.......glad I moved North
