I enjoy using my Safari detector, but at 75 years of age, I cannot swing the 11" standard coil anymore and have replaced it with the SEF 8 x 6" coil. I like that coil very much especially for trashy parks. However, the few silver dimes I continue to find are mostly Mercs at the very edge of its detection depth. I'm looking for a new coil with a little more depth, but no additional weight. I recently noted that Detech has just put on the market a 10 x 5" SEF WSS coil for Minelab detectors. Has anyone tried this new coil yet? I believe it is even lighter than the SEF 8 x 6 coil. Does it have a bit more depth than the 8 x 6"? If so, I definitely would want to purchase one for my Safari. The ads so far also do not indicate whether or not this new coil is waterproof--Is it? Thank you for any advice you can give me regarding this new coil. I want to continue with the hobby I truly love for a few more years yet.
