I'm not sure if Dilek understands iron bias or if there is a translation problem. She said in the video that the Legend has "fixed" iron filters. I'm guessing Park 1 has a higher discrim setting built in since Park 2 was trying to hit the coins. This is bad from my point of view. Iffy had it accepting everything (no discrim) according to the menu, but it still has an active iron filter? That is worse than an iron bias set too high because it can at least be turned down. If they add iron bias on top of an internal fixed iron filter, that is going to be a disaster. The nail board tests are fun, but kind of useless. Elevated iron tests, or any test where iron is on a different plane is the better test for separation. The Legend seems to have had a rough start in life. Hopefully they get this straightened out.
