Explorer SE vs SE PRO
Posted by: Jaichim24

Hey, I was reading some other posts and googling around trying to find the exact differences between the SE and the SE PRO. When the PRO first came out I had been under the impression that the only difference was the coil. Reading around a bit more, several years later I've found references to slight differences in the grip, a faster processor, updated firmware for 2010, and perhaps (if it's different than the firmware) some differences in the software. I'm a bit interested in the change to the processor, and the firmware/software. If it's a faster processor, it could possible lead to a faster response. The firmware could just be tweeks to the software for better ID and more accurate information relayed, and perhaps better utilization of the faster processor.

I can't find any reference to the actual speed of the process on the SE and SE PRO. I know the eTRAC has a 32bit 48mhz processor. Anyone have this type of information for the SE and SE PRO. Can anyone confirm or support some of the other changes I've heard were made?

My SE is at Minelab being serviced and I may ask about upgrading, just wondering if it'd be worth it, I've heard it could cost between 300-400 dollars.

Thanks,

Jai

I to was always under the impression that the only difference was the coil on the SE & SE PRO.------It will be interesting to see the responses you get on this.-----$300 to $400 sounds like an AWFUL LOT of money for an upgrade.

I have the SE, slower or not im plenty satisfied and havent upgraded to the Etrac so i dont think $400 would be much of a temptation for the benefit. You might check the patent. Ive read it, but dont remember it talking specific tech talk on the box. Good luck on your search.

I'm pretty sure this topic was recently addressed and if memory serves me, Bryce had said and please dont qoute me that there isnt really any difference between the SE and the Pro except the coil and the speed is about the same.
What type of processor does the Etrac have compared to the SE?
Thanks!

If there was much of a difference id think ML would have been promoting it as a REAL upgrade... and the greatest thing since peanut butter. If they didnt they missed an opportunity which most dont. I think it was a way to bring the SE to a point where many of the companies have went..... to a larger coil only. Which was one of the best moves in many years.

I like the point about if it were a true upgrade Minelab would have been promoting it. I'll have to ask about that. Someone on another forum told me that the processor upgrade would affect it's ability to detect and it's response time, but rather how fast the digital display appears. They didn't mention tone ID. I would have loved to improve the response time.

The E trac is so fast it will burn your house down! dont get the e trac its a fire hazard. :crylol: lol lol lol

I don`t know about the differences, all I can say is my Se Pro found 10 wheaties, a buff nickle, a 42 jeff, 2 clad dimes, and a beautiful 1917 merc at 8 inches, all in about 3 hours today. It was also at at a house that produced zilch with my old Garrett. I love this thing and only have 6 hours on it.

Well It turns out that my processor may have been going on my SE. I spoke to several knowledgeable people at Minelab and was very pleased with the interaction, answers to my questions, and the degree in which they worked to help solve the problems I was having with my SE. They did a lot of extensive testing to trouble shoot the root cause of the problems I was experiencing.

To clarify on some of the above discussion. Each coil has its own type of mini processor, the coil projects the electromagnetic field and detects everything it can based on the FBS technology. (the 28 different frequencies cycling) It then passes that raw signal up to the control box, which has its own processor. (this processor is a set of boards, a PCU, firmware chip, filters and firmware etc) This processor along with some various electronic filters "processes" the information in conjunction with the firmware and "ID's" it based on the settings your request via the firmware interface, whether it is a tone ID or a digital display. Obviously it takes more processing power to convert these signals into a digital display versus a tone ID. The more variability, the more discrimination, the more processing that is required.

So, the faster the processor, the faster it processes the data the coil (which is always "detecting" full speed/best capability). In turn, a faster processor should increase the response time you get in-between targets, as well as the Tone and Digital signal the detector displays.

All this being said, the tech only had available to him, the same processor specs we have available. Minelab has only posted the specs to the eTrac processor which is 32bit running at 48MHz. I could get from the tech that the original SE processor, is slower than the SE Pro processor, and that the SE processor is different than the eTrac processor. Whether different means one is faster than the other cannot be determined. It could just be a different "chipset" to use computer CPU terminology, but have the same over all processing speed. My personal opinion is the eTrac processor is most likely faster than the SE Pro processor.

Another addition you should know, is that if you replace the processor on your detector, it's just not the processor that gets replaced. Like I mentioned above, it is a set of boards that includes the processor, firmware chip etc. They currently only use the SE Pro processor/board set. So you would get the "faster"processor and most recent firmware etc should you require a replacement or desire an upgrade.

I could not get confirmation on any "2010" firmware, or if there were any differences between the original firmware for the SE or that which is being used for the SE pro. (other than if any changes, new processors would have the SE Pro firmware) My person opinion based on my computing experience (I build computers) is that the firmware would most likely have to be updated to some degree to compensate for the faster processor. (IE needing a new BIOS on your computer to recognize a faster processor) Obviously there are small bug fixes and other tweaks that must have come up. So logic could dictate that some other changes to improve minor things were most likely added to the firmware. However, I doubt the changes would make any noticeable difference, other than the improvement with the faster processor. (which I feel could make a real difference)

Lastly, cost, which will probably turn off most people. Part prices are static and there is no negotiating, the price for the replacement processor/board set is around $375, tack on at least 1 hour labor at around $65 and you're over the $400 mark. Return shipping is a flat $15 UPS 3 day. I had the front keypad replaced (part is around $27.50) the processor set, and the upper cam-lock clamp (~$12) area replaced on my SE and the total came up to $448 including shipping. Just a FYI the foam grip if you want a new one is like $10.50, and the strain relief and connector (what you connect the coil plug to) the part alone costs $50. However, my changes have affectively turned my SE to an SE Pro.

Some additional info: The tech did a full inspection of all the wires and connections and did not find any corrosion. I purchased my SE used from eBay back in 2008, and it was originally purchased in 2006 or maybe 2007. I definitely use mine a lot, but I don't feel I abuse it. However, it does get exposed to plenty of dirt, dust, and mud. The tech did report that the interior of my detector was covered in a fine dust. He said that it works its way in. The speaker is one obvious way in, but he mentioned that the speaker housing also acts as cooling for the processor and interior of the detector. Something to keep in mind should you decide to seal up the speaker. For the majority of my ownership of my SE I did not use a dust cover on the housing, no matter the design I find it adds to the glare so you cannot read the display. For most of the last half of 2010 I did have one on. The tech also said he installed a moisture crystal packet inside the housing which should help prevent moisture affecting the electronics. I thought that was a very nice touch and a sign of their dedication to quality and service.

Well, that's all I can think of to talk about, I hope that sheds some light on some questions you all have and hope it contributes to the knowledge that is out there. If I think of anything else, I'll update this post.

Jai I think you think to complicated about so old technology, dust cant pass through speaker, its glued with hot glue and its tide. only one place for dust to come, its where push button panel meats housing , this place you can tape with scotch, because in this connection is no any seal plus it will help from rain. small hole in handle for headphones and battery wires where control panel connects handle, too some way for dust, but you have to swing detector one year in desert to collect enough dust to make any problem . You can cover control panel with pillow its will not effect any way. Open your self control panel and learn, if you want can explain how to open. good luck Stasys
