Like many, I got mine at closeout from RS. Depth was only so-so. A better machine will give a whisper signal on deeper stuff, the 3300 just nulls out... it either hits hard or not at all.
Hunted alongside an old Garrett Freedom Ace plus (not a depth-demon by any stretch) in the bark-chips. The FA+ hit harder on faint targets than the 3300 did. Surprised the heck out of me!
I DO like the features on the 3300 and would have kept it, but the deal-killer was target separation.
In iron, my Tesoros blew it away and for coins in pulltabs, my Garretts were superior.
In short, every time I'd use the 3300 I'd be wondering what I was missing.
For target separation testing I'd surround a nickel with nails, and also a dime with pulltabs and see which machines would hit using stock coils. The 3300 didn't do well against the others in either test.
I can handle 'average' depth capabilities in a machine, but I GOTS to have good target separation.
Not brand-loyal here, I'd use a pointed stick if it got me more loot. Just my observations with this one BH model. No offense intended.
