Impact is a very nice machine. Very good hand grip texture and shape, so comfortable even after hours of use.
The batteries being at the back is like Fisher Fseries, and a better design than the Racers imho.
I like how everything is at your fingertips. Very easy to switch modes and adjust settings.
The all-metal modes are great, and being able to hunt in a proper motion all-metal mode with threshold, and having an iron tone break is wicked!
Built in wireless transmitter to pair up to Nokta or Makro headphones is very nice.
So many modes to pick from, VCO modes or beep modes with various degrees of recovery speed/gain etc dialed in, you'd be hard pressed to NOT find a mode to your liking, for the type of hunting that you do.
This is probably the only potentially overwhelming aspect of the machine - which mode do you go for! I suggest users start off exploring one mode, and then when they feel comfortable check out another one. You will soon work out what you like.
Compared to other machines, the build quality is very nice, and up there with the best. I think it is faster than the CTX3030, but the 3030 is maybe a bit more stable on deep high conductors. Compared to the tame X-Terras, the Impact can be like a raging bull, but you can tame it down with the VLX modes. So, the Impact is really a tool which you can run to your preferences, and that is what I love about it.
The Impact all-metal mode in 20 kHz is also a capable gold machine, especially with one of the smaller coils, as it's all-metal mode is as good if not better than any VLF gold machine.
I think it is one of the best all-rounders ever made, but if you like to play near water, then the Multi Kruzer is likely to get a look in due to 5m waterproof!
