I use the 5x9 sharpshooter on my Gamma and it works good for all around hunting and is not too bad in EMI situations with the heavy wiring. I use the stock concentric coil 5.5 x 9 (10 inch) on my Omega. To Me, this is just a elongated 5.5 inch coil. It is a good all around coil, with reasonable depth. It works better than the sharpshooter in real close metal structures. I'm not saying it will work better than the sharp 5 inch coil around metal structures, but it will cover more real estate. I will try the 8 inch coil later on the Omega as well as the sharp shooter. I have no desire as of yet for the 11inch DD or the Sharp. For beach hunting I think the 11 inch would be tough to beat, the sharpshooter takes care of most my open area hunting for now.. JMO HH
