I bought the 11 inch round to try and get a bit move coverage quickly.
1. Slightly noisier on same ground and similar settings. 2. Had to swing it slightly slower to pick up same targets 3. Targets were slightly fainter thereby meaning i was not actually getting the best range anyone.
Recommendation: pass on the round coil and at $375 a through + fitting kit I wasn't that impressed. If some one loaned me the 14 x 9 i would have a go but not going to use the 11in again.
