The MXT's and M6 are some of the better models available in production today. There are some makes and models that can also respond quickly, but have a little lowered recovery rate in order to respond to the next nearby target. Some have an obvious delayed response, naturally, and that can work against a person if hunting in a densely littered or target saturated site.
The video does show a quick response to what appears to be the nails in the flooring, but that's because those are accepted targets with a lower disc. setting. In the field, for most hobbyists, that isn't how most people need to evaluate the overall performance which includes the recovery speed as well. If hunting in a trashy site, you need to have a reasonably good response to a desired target located amongst the trash. For most, the trash would include iron and similar lower-conductive targets that people usually have rejected by using an increased Discriminate level.
If you are trying to find a small coin in a heavily littered site that abounds in iron nails from torn-down or burned-down structures, you have to also factor in not just having a quick response when you sweep across a good target, but how the detector handles the task of rejecting (going silent of having a negative response) those iron nails and then being able to recover from that rejection response in order to still produce a hit on a desired nearby target.
It's one thing to be able to respond to a series of nearby targets that are 'on end', such as the nails in the wooden flooring, and accepting them all, but that can differ from rejecting those iron nails 'on-end' with a good target placed between them. It's even more difficult to try to reject a cluster of iron nails that are laying on the ground in various relationships to the coin and still be able to recover from that rejection response and respond to the good target.
Of all the current hobby-end models in production at White's, I also feel the M6 and MXT's are the best they make to handle this task! Hobbyists who view your video and similar offerings can see how well the MXT/M6 models can quickly response to closely associated targets, and that is good. But there are going to be a few things they need to keep in mind and that is:
1.. Know that visual target ID will often be inaccurate for good targets too close to rejected junk.
2.. It is important to use a minimum Discrimination setting or there can still be target masking.
3.. When working sites that have a densely spaced amount of targets, good and bad, best results will call for the use of a smaller-size search coil.
4.. Also, when working very target saturated sites, a slower and shorter-length sweep speed is also very important to allow the circuitry to reject, recover and respond to the nearby associated desired finds.
There are some trade-offs that also need to be learned and appreciated when ti comes to comparing quick-response/fast-recovery models and that is that many which are more digital designs might still not work as well as some of the good old analog type circuitry White's and others used to make.
Yes, I have liked the 4 M6's and 6 MXT's I've owned in the past, and the MXT Pro hit my 'buy-it' list, too, with the added new features. There are a few other competitors models that also show a quick response, such as the Garrett AT Pro, Teknetics Omega or G2 or T2 or Fisher F5 and F-75. I know what they can do, but I also know what the White's Classic series models, such as the IDX Pro, can do in iron nail infested sites.
