Popular Post ColonelDan Posted May 10, 2022 Popular Post Share Posted May 10, 2022 I took my D2, with underwater antenna attached, to Cocoa Beach for its maiden run after updating it. My primary objective was to test the stability in salt water and develop a custom program I could use as a start point on subsequent salt water beach hunts. I used the factory Beach program as the base and made adjustments from there. After doing a frequency scan, adjusting sensitivity for EMI and staying in the Tracking mode since our beaches are very much uniform in mineralization levels, I started off in the dry sand and progressed to the damp and then the wet sand. As expected, it was solid...quiet and stable. I then got into the surf and it started to chirp as the waves washed over the coil. I began to make adjustments to the Salt Sensitivity and Reactivity settings which began to noticeably improve the stability. As I continued to experiment with the settings, I found the following was optimal at this beach on this day: Discrimination = 6.5 Bottle Caps = 3 Silencer = 0 Sensitivity = 93 Salt Sensitivity = 4-5 Reactivity = 2 When the coil was initially exposed to the first wave action washing over it, there was chirping. However, when the coil was fully submerged to about 1 foot or even less, the chirping originally caused by that wave action, was gone. I began to sweep the coil for targets and all was quiet except for the occasional blip now and then. All in all, 0.71 was solid in all salt water environments...dry, damp and wet sand and surf. The above settings were saved to a custom program that I'll use as my start point for salt water hunting. Remaining settings are just personal preference such as iron volume, audio response, audio out and 4 tones modified to 3 tones. My next objective for submerged operation is to develop a custom program for fresh water hunting since our Seminole War site is in a fresh water lake. One personal nit picky point; installing the antenna and removing it for after operation cleaning is somewhat of a pain I could do without. I'd prefer another approach but I understand wireless limitations so I'll live with it. 😉 10 1 Link to comment Share on other sites More sharing options...
cdv Posted May 10, 2022 Share Posted May 10, 2022 Interesting for sure. Over on the Gulf side, I run the same settings in Beach Mode except Salt Sensitivity = 7 Reactivity = 0 I will say I experimented some and I decided to run Audio Response up to 7 to "hear" the deeper targets easier and found (like mentioned in the manual) it will light up all the smaller surface targets.... it was too chatty for me so I dropped it back down to 6. All together it is very stable in the water. I'm still on version 0.7 Cliff 4 Link to comment Share on other sites More sharing options...
F350Platinum Posted May 10, 2022 Share Posted May 10, 2022 Very nice post, thanks for being so detailed on the settings, and which program you based it on. 👍 1 Link to comment Share on other sites More sharing options...

CPT_GhostLight Posted May 10, 2022 Share Posted May 10, 2022 Thank you ColonelDan for your excellent report on your recent beach exercise. While it will be a while until I make it to a salt water beach again, it's good to know V0.71 is behaving correctly for the task. I look forward to making it out to the Right Coast again. 😎 1 Link to comment Share on other sites More sharing options...
ColonelDan Posted May 10, 2022 Author Share Posted May 10, 2022 All, Thank you for those kind remarks. They're very much appreciated. Please keep in mind that although those setting of mine may be a good start point on salt water beaches, they aren't the magic formula for universal success. Every beach is different so you'll have to adjust the settings to the conditions at your specific site. As I've always said, ~Predetermined settings serve only to get you in the ballpark. It's up to you to pick the best seat~ 😉 Good hunting.... 4 Link to comment Share on other sites More sharing options...
Steve Andrews Posted May 11, 2022 Share Posted May 11, 2022 I've found 0.71 to be very good on the beach, though I've had no problems with any of the versions to date. I generally hunt high VDI relics; 19th century British lead bullets, large cast iron shot and brass artillery fuzes and WW2 German-fired brass and aluminium fuzes. For these high VDI targets I favour the low frequency weighting of the Diving program as a base, with reactivity dropped to 0, sensitivity up to 96 and using 5 tones, with breaks for different categories of relics. I use the large numbers profile. If I'm on a jewellery recovery I use a program based on Beach Sens. Reactivity 0, full tones and using the XY screen. 1 Link to comment Share on other sites More sharing options...

cdv Posted May 11, 2022 Share Posted May 11, 2022 No tracking and down here, GB rarely changes from the preset value. I'm sure on some beaches I'll need to give tracking a try but so far I don't see a need for it. Link to comment Share on other sites More sharing options...
