I'm the guy selling the E1500.
There were a lot of little things that annoyed me with it, but they all add up. The main issue is it costs me gold. I've gone over the same ground using my SDC2300 and found pieces the E1500 missed. A friend using his Gold Monster picked up a small specimen in a patch I'd checked twice. I found myself covering a lot more ground quickly and confidently with the 2300.
I wasted a lot of time digging for ghost signals due to ground noise, even after ground balancing within a meter of the area. I don't want to have to keep my eyes on a screen to notice when the ground balance is off at one end of a swing.
With the Sadie coil on faint signals, often no numbers in the discrimination/pinpoint mode would show. With the larger coil in pinpoint mode, it would threshold drift and scream after ten seconds.
Changing coils is fiddly; you have to line up two sets of holes, one on the shaft and the others on the plastic spacer that can easily push down the shaft or turn slightly. The shaft isn't rigid enough for my liking, flexing under the weight of the larger coils. The design decision not to ship it with the rotator stop in the top joint means there is slop in the joint, which, with larger coils, allows it to loosen by itself.
Cable bump noises are very noticeable, even at the top where it enters the controller.
The inbuilt speaker is not crisp, clear, or able to go to a decent volume. My Gold Monster volume setting of 1 is louder and clearer than the E1500 at its maximum of 9.
Ultimately, it's all about the gold. I've only had the 2300 for just over a month, and interestingly, I paid about the same price secondhand for the E1500 body only. I tried to force myself to use the E1500 every day first thing, but I often stopped using it sooner than planned as the 2300 just gets out of the way and lets me concentrate on the ground in front of me. If anything needs to be changed on the machine, I don't even need to look at it. I can just feel there are no multi-layered options menus. I don't have to constantly re-ground balance from swing to swing. I don't need to view a screen or check a number, as the speaker is clear, loud, and expressive enough to know straight away if it's something worth investigating.
I was really excited when I first investigated the E1500, I'm sure a lot of people will love it, I'm just really disappointed and although they offer a thirty day money back. I've spent hundreds on coils and battery packs I have nothing else to use on, that's why I'm selling it. I hope Algoforce does well and becomes a worthy Australian competitor to Minelab.
