12.5-inch EXcelerator coil - Field Test

A

Anonymous

Guest
After several months of empty promises, I have completed my field test on the 12.5-inch EXcelerator coil. Some of the delay has been due to health issues and some has been due to the 12.5-inch coil itself. Let me explain. I received my first 12.5-inch EXcelerator coil (a prototype) in February. February is not a good time to be out metal detecting here in the Midwest. Snow, cold, ice and frozen ground make many of us armchair detectorists for several months. But after the snow melted and the ground thawed, I was out testing the 12.5. From the first time I connected it to the lower rod, I knew that I liked the feel of this coil. To me, it seemed to be better balanced than the 14-inch Excelerator I had tested earlier. In addition to previously testing the 14-inch Excelerator on my MXT, I had also purchased the 5-inch Excelerator for the MXT as well as the 5-inch EXcelerator on my Sovereign Elite and the 12.5 Excelerator on my Advantage. Based on the other Excelerator
 
I think you would have to qualify the comment about using one in a ghost town, however, because it depends on the town itself. I feel such coils have some good potential on the <EM>fringe areas</EM> of ghost towns where you're looking for any site of past activity. Yes, in some low-target townsites the bigger coil is 'OK' but certainly NOT in the densly trashed, iron-infested old RR towns and similar sites.
I head out next Wednesday morning for a week of enjoyment with a couple of friends. Most of the old town sites we plan to hunt are RR towns, and there is a lot of iron junk and just nasty scattering of old trash. For that, I plan to use the 5" EXcellerator most of the time.
We will have some 'fringe areas' to be hunted, and we're also going to be working some large plowed fields in the next few weeks, if not on this jaunt. I'll be taking the 14" EXcellerator as well as a 12
 
Bad back and neck? THAT sounds familiar. Four surgeries later and ........ Oh well. Those are good points you make about ghost town locations and the weight of the coil. The ghost towns I hunt are simply old rural towns of the mid to late 1800's that are now farm fields. I have researched old plat maps and have identified the sites of old parks, churches and schools. Not the same as wandering through an old RR town, I am sure. As to the weight of the 12.5, I will be interested to see if you find it as well balanced as I did. I have my Sunray probe mounted with both bolts, so I had the lower shaft of the MXT extended fully out. If I were to hunt for long periods of time with the larger coils, I would remove one of the bolts from the probe and shorten the shaft a notch. Even fully extended, there is no comparison between the 12.5 and the WOT I use to swing on my Minelabs. Good luck on your trip and let us know your findings and analysis. HH
 
The front label on the box says (in part): "Do not use the Coins program of your detector." "We recommend the use of Relic mode or any program with lower discrimination level. This is a professional Relic Searchcoil and the Relic Hunting requires low discrimination levels."
I do recognize that lowering the discrimination level on most machines will increase the sensitivity. That is why lots of folks run on minimum discrimination. Makes it seem like it goes deeper. I do not believe that there is a technical reason to not use the Coin mode. If there is, someone please explain it to me. DETECH's statement makes me wonder that by encouraging us to use a lower discrimination level in Relic mode (as compared to running in the Coin mode), we maximize the performance of the machine. (lower discrimination = increased sensitivity) When we see how much deeper it goes, we credit the "Professional Relic Coil". Who knows?? <img src="/metal/html/confused.gif" border=0 width=15 height=22 alt=":?"> All I know that while testing it, I was able to use both modes effectively and was impressed with each. I should also add that I generally use the Coin mode with all my coils and do not notice much (if any) difference in depth of performance, compared to Relic mode. Some people like the dual tone and some of us like repeated tones. I happen to like the repeated tones of C/J. Thanks for your comment and HH.
 
Thanks for that info!! Would you happen to know if the 12.5 coil gets a bit more depth than 6x9DD Eclipse coil.
Thanks again..RonL
 
Ron, Although it is subjective, I do think the EXcelerator gave a more distinct signal on deep coins in my test plot than the Eclipse does. Where the 6 X 10 Eclipse gave a soft, faint signal, the 12.5 EXcelerator sounded off loud and clear. Same targets, same settings and same Gray Ghosts. Although I did not find any deep coins with the 12.5 in my field test (other than in my test plot), both coils were hot on those square nails I mentioned and the EXcelerator picked up signals where the Eclipse had not. Can't wait for the weekend to take it out again. HH
