Erik Oostra Posted February 3, 2022 Author Share Posted February 3, 2022 13 minutes ago, Jeff McClendon said: Equinox Beach 2 and Deus 2’s Diving mode again on paper are operating at very similar frequency weighting and should have similar results. If they don’t, then your Salt Sens theory may be for real. From what I can make out from the manual, in the Deus II's Beach program the range of available frequencies are 4.08 to 4.76 kHz - 6.94 to 8.08 kHz - 10.39 to 15.15 kHz - 15.62 to 20.75 kHz - 22.06 to 28.57 kHz (topping out at 24 kHz) compared to the Equinox’s Beach modes using 5, 10 and 15 kHz.. The Diving program has multi-frequency ranges up to 14 kHz.. The manual says that ‘’unlike some multi-frequency detectors that offer fixed multi-frequencies, the Deus II uses different high and low frequency combinations depending on the programs… These frequencies can then be subtracted to remove electrically-conductive soils or added together to help locate a wider range of targets’’.. Perhaps it's all a matter of 'fixed multi-frequencies' vs 'multi-frequency ranges', but I'm finding that the Deus II's Conductive Soil Subtraction together with adjusting the salt sensitivity settings gives the Deus II an edge over the Equinox in seawater..

I think you are mis-reading the manuals of both detectors. Equinox Beach modes are multi frequency only and have been shown to both run a low frequency (below 10 kHz) and a higher frequency around 20 kHz for Beach 1 and around 14 kHz for Beach 2. the 5, 10 and 15, 20 and 40 kHz selectable single frequencies don't apply to them. Deus 2 in it Beach modes is running at least two frequencies like the Equinox and has a lower one (below 10 kHz) and each modes higher frequency is printed in the manual which says, Diving has a maximum of 14 kHz, Beach has a maximum of 24 kHz and Beach Sensitive has a maximum of 40 kHz. If you can run Deus 2 Beach submerged (maximum of 24 kHz) you should have a big advantage on a wide range of target sizes and conductivities compared to Equinox which has to run Beach 2 submerged (maximum of 14kHz, probably). Throw in Salt Sens and submerged the Deus 2 Diving on paper equals or beats the Equinox Beach 2 and if you can run Deus 2 24 kHz Beach submerged, its no contest plus your Deus 2 can go to 66 feet, has bone conduction headphones (which should really help you with your hearing loss) and Deus 2 hasn't leaked so far. For a saltwater diver like you, Deus 2 hands down is the way to go. 1 Link to comment Share on other sites More sharing options...
Jeff McClendon Posted February 3, 2022 Share Posted February 3, 2022 If a Deus 2 is able to run Beach Sensitive (maximum 40 kHz) on any given beach and an Equinox runs Beach 1 (maximum 20 to 24 kHz) there is no contest if one is trying to detect micro jewelry like a .5 gram 10K gold earring back buried at 3". The Equinox might hit it but Deus 2 running Beach Sensitive in that scenario is going to win every time. If Deus 2 can't run Beach Sensitive due to instability and has to run Beach (maximum of 24 kHz) the results will be closer. Its not magic, its just physics.

Sorry for the sketchy replies Jeff but the internet keeps going down at my house.. just took my laptop down the beach and am sitting under a palm tree so I can get online again.. I've tested this underwater on a small gold ring.. cranking the salt sensitivity settings right up did not make the target disappear.. nor did it seem to effect the sensitivity of the detector no matter how deep the ring was buried.. 4 hours ago, Jeff McClendon said: I would still be careful about cranking up Salt Sens to 9 on ring finder type dives for customers. That is why I added the caveat in the manual to my earlier post. I'll heed your good advice here Jeff, I usually run the detector between 6 to 8 anyway.. I cranked it right up on the job because I'd checked that the salt setting works on a similar ring without losing the target.. I've been testing different sized rings (gold and silver) buried at different depths so I know what I'm looking for on the job.. 1 Link to comment Share on other sites More sharing options...

Throw in Salt Sens and submerged the Deus 2 Diving on paper equals or beats the Equinox Beach 2 and if you can run Deus 2 24 kHz Beach submerged, its no contest I run my Equinox on Beach 1 when diving as Beach 2 is less stable.. for the same reason I've been running the Deus II in Diving rather than Beach or even Beach Sensitive.. Not sure what's going on under the hood as to which frequencies are operating at any one time, but I have noticed with both detectors that running at higher frequencies destabilises them.. I know that on paper at least I should have an advantage of a wider range of targets, but in seawater I'm limited to what programs I can use.. 1 Link to comment Share on other sites More sharing options...
Jeff McClendon Posted February 3, 2022 Share Posted February 3, 2022 Equinox Beach 2 runs lower frequencies than Beach 1. That is a proven fact. No debate. So your saying Beach 1 is more stable in submerged saltwater than Beach 2 is very puzzling unless there is an EMI source near where you are diving that is effecting Beach 2. 2 Link to comment Share on other sites More sharing options...

Didn't know that.. but how low is low? Is there much difference? In my experience Beach 1 runs stabler than Beach 2 underwater.. I can't explain why, it's just what I've noticed with my detector.. maybe the higher frequencies in Beach 1 are still low enough for it to run stable in seawater (unlike those of the Deus II Beach programs)?

Lke I said a couple of posts earlier, Beach 1 and Beach 2 have both been analyzed. Beach 1 has a lower frequency below 10 kHz and a higher frequency somewhere between 20 and 24 kHz. Beach 2 has a lower frequency below 10 kHz and a higher frequency around 14 kHz. Sensitivity to smaller targets of all conductivities is much better using Beach 1 compared to Beach 2. You can test that yourself on 1 gram or smaller targets, especially lower conductors. 1 Link to comment Share on other sites More sharing options...
