I am a newb and wanted to start off with a moderately priced unit, read review after review and chose the Delta. I have had shoulder problems in the past, but I can swing it for hours without any pain. I like the fact that it uses only 1 9V battery and gets around 20 hours each as well. I have found numerous items; relics, rings, clad and silver (and of course trash). I plan on making some videos in the near future, if it will ever warm up!
It is a deep machine....I have retrieved a few coins at 8+ inches. Nice to know about the coils, I took advantage of an 11" coil deal when I purchased my detector. Almost wish I had purchased the 5" coil too. I will be upgrading at some point (another Teknetics), if and when I get the itch, so I may be calling to check on those discounts!
I to am a recent buyer of the teknetics brand I got mine from Bart and he's a great guy to deal with.
I had a whites mxt and like you I have shoulder problems and wanted something lighter so decided on the omega.
Have only been out a few times due to the weather but it's not disappointing me at all the depth is good and the vdi is locking on deeper then my other one did so I'm really happy I got it and I'm sure you will be too.
