Detech Ultimate on the beach

Finally got to the beach with the new coil. Daytona beach to be specific. No pictures of mind blowing jewelry or Spanish gold but did find a decent pile of clad. Out of the six hunters I knew of 1 hit a silver chain and the rest of us found junk jewelry and clad. But on to my impressions of the coil.

Just as on land it gives more positive audio on targets. It just seems to "talk" louder over coins, especially the deeper ones. I was running with deep off but even the nickel that was about 10" was loud and clear, no iffy audio about it. The lead fishing weight was a little more "hazy" but it was a long oval weight with a cast in loop. Wonder if that had anything to do with it. Had one that was bouncing numbers and crazy audio that I had to dig out of sheer curiosity. It was a flounder rig with two mangled stainless hooks, a large lead pyramid weight and large brass snaps.

The three nickels I found all registered as 12-13's whereas this coil normally hits them 12-12 in the dirt. The other coins all rang in pretty much spot on number wise. Could be the salt.

This coil really hits copper hard and copper wire in particular. A strong signal at 6" brought up a nice wire scrap. Looks like 4 gauge marine cable about 4" long. It brought up a lot of deep pennies as well.

My one piece of jewelry was a small toe ring with failing silver plating. Nuts!

Now to the aggravating part. The coil cover, like most of them collects sand and that includes some of the black stuff. At one point I was checking a signal my partner hit with an AT-Pro. I couldn't get a thing until I went to pinpoint at got a faint deep sounding target. That bothered me a bit. It was deep iron but I couldn't even get a null. Hunted a bit longer and was swinging in the wash when it started chirping like crazy. Noise cancelled with no improvement. Checked where auto sense was and was down to 16! Then got smart and pulled the coil cover off and found some sand and black sand under it. Fixed that problem quick and everything started working the way it should again. No more coil covers on the beach. My other covers have been replaced with bed liner and this one is in for similar treatment. Right after I pulled it I went back to digging deep targets again and the auto +3 sensitivity jumped back to the mid twenties.

As for sensitivity settings I'm getting it to run better in auto +3 then manual. In that mode today covering everything from loose dry sand to shallow wading I saw settings from 29 to 18 with very little falsing. Tried running in manual from 26 to 20 and it was falsing almost every swing in several different spots on the beach. I'm just going to live with auto +3 as it seems to do that hotter then the stock coil where ever I've run it so far.

Over all I'm really liking this coil and unless I need my X-5 for trash it's going to be my primary coil now. No retirement finds yet but still looking!
 
Good report Sailorman.-----Question: How much does the 13" Ultimate coil weigh (without coil cover)?
 
Don't have a scale handy but I notice no difference between the Ultimate and the Pro coil.
 
If you do a search for "Ultimate" in the Explorer forum, Bryce has done some extensive field reports on this coil. I also posted links in at least a few of those threads to link them to others, and to at least one review that is found here in the Etrac forum too. The weight thing is also covered. I think they said it weighs just a tad more than the Pro Coil and was a very light coil.
 
This thread has a chart (make sure you scroll down so you are looking at the last updated picture of that chart and not a early version in the thread with less coils listed) I put together with the help of others on the weight of various FBS and BBS coils. According to the weight I found for the Ultimate it is actually LIGHTER than the Pro Coil. However, take that with a grain of salt, because I don't remember if it was the FBS or BBS version. At least with the SEF coils, the BBS versions weigh a bit less than the FBS versions for some odd reason, so it might be the weight I posted of the Ultimate (found near the end of that thread) was the BBS version.

Either way, if anything I think I'm pretty sure I've at least read the Ultimate FBS coil was perhaps only a tad more heavier than the Pro Coil if memory serves. Regardless, it's either going to be a tad lighter or a tad heavier than the Pro Coil if those points above are any indication. Somebody correct me if I'm wrong.

The BBS version of the 12x10 without a coil cover is only about half an ounce heavier than the Pro Coil, and in fact is lighter than the legendary light weight of the S-12. I use spray on bed liner on all my coils to protect the bottom and not hassle with cleaning under coil covers. If and when I get the Ultimate, I think I might spray the entire coil top and bottom with bed liner so it's black, because I saw that done with a WOT coil and man did it look like it was fresh from the factory and meant to be that way. Spray on bed liner puts a pattern on a coil just like a factory pattern black finish that most coils have.

Either way, here's the FBS/BBS coil weight chart. Whether each coil is FBS or BBS is noted in the chart. These were weights by actual users measured unless noted otherwise in the chart, because we all know the reported weight by factory specs can be much different than what it actually is. If you have any coils you'd wish to add to this thread please feel free to do so. Include the coil cable on the scale, and weigh the coil with and without coil cover.

I use a bead of silicone bathtub caulk around the seams on my coils to keep out the dirt/debris and water.....works like a charm...
