Hi Gary, The quick answer is yes, quite a bit. The 5000 comes into its own on the deep gold, and the large area you can cover using the larger coils. Find it then clean up with 2300.
We did try an 8 inch coil for comparison but the 2300 was still better on the sub grammers. my test piece is .25g, but we were getting gold to small for the scales est .05g maybe even smaller. I think maybe the 5000 with a small coil and a very experienced operator may get there, the soil, what there is of it, is so highly mineralized that you have that to contend with as well.
The 2300 you can take it out of your vehicle,cancel the electrical interference noise if any, set threshold i find 1.5 to 2 leds a nice easy to listen hum, ground balance and you are away it even seems to automatically GB itself after that. When turned off it remembers your previous settings. It does have about 8 different ground type settings,3 for salt, that you can select. Just left it set in the green #2. There are a row of 9 leds. I found them to be of great help when detecting you think you hear a target and you can go back over it watching the leds, 1 is on all the time the 2nd just coming and going,when you are onto a target (sub grammer) the 2nd led will stay on and the 3rd flash until you have it pretty much pinpointed, some times you will hear it some times not. Large targets the whole 9 go and it blows your eardrums apart. The 5000 picks up a lot more ground noise and I think you miss the small stuff partly for this reason, this is where experience comes in.
A few things about it that Im not happy with (cant get it perfect). the first day out the wires came apart at the plug for the headphones, cable to short for gold detecting, a few fixxes, when you find a target unplug the headphones and take them off use the on board speaker to help recover your target. Failing that collapse the coil shafts it's easy enough. dont use headphones we found plenty of gold without them, but it's a bugger by machinery or wind. Set up as shown in enclosed picture, met a guy who also had the same problem as us, wires got pulled out of plug. he has an amplifier speaker, notice the small light headphones, they hang under the chin so you can wear a wide brimmed hat
Available now are extension adaptor leads from Phase Technical made by Nenad Lonic (he used to be minelab australia's technician and is now out on his own) email:
[email protected] As you would expect they are expensive $103au. Reeds Prospecting in Perth stock them $110au they also have remote speakers $40 and amplifiers $140 so you can set the noise up beside your good ear, on the harness $85. bungee set up $42. Ive made my own bungee and harness out of bits and pieces as you do, get a dee fixxed onto your backpack and you are half way there, the shoulder gets pretty painful after a few hours swinging.
With a bit of luck Chris from DetectNZ may source these, be something extra to put on the accessory webpage, we should support the guys here, Im sure he can beat the aussie prices.
The other niggle with the sdc2300 is the elbow rest and strap the strap is awkward and a pain to keep adjusting velcro would be a good fix. the collapsable rest wants to collapse when putting your arm thru especially with long sleeves. The fulla whose detector is in the photo his collapsing bits are not far away from disappearing he is going to use a bit of 100m plastic waterpipe to sort. his detector is the machine he uses almost solely now, his 5000 and other detectors stay in the camper van. He had just returned to the town camping ground from a walk for about a hour around the local watertank with 3 nice nuggets when I caught up with him. An area that's been thrashed for years.
Dont get me wrong these detectors where designed for the military. The guy swinging the detector won't be digging the mines so the headphones would be heaps long enough and he wont be putting it on the ground every 5 mins so putting your arm in and out of the elbow rest wont be worrying him either. the way they collapse and fold away is a brilliant piece of design fairly rugged as well, not all flimsy.
The other photo is of a days collecting for us.
