I've had no issues with my Racer 2 or coils so far, being a second generation detector it should have most bugs and QC issues sorted by now. As Nenad mentioned, it does run very well for a VLF on the beach, even better than my Deus with regards to achieving a good ground balance. Depth wise it is on par with the Deus, possibly even surpassing it using the deep setting or with larger coil options. As with most VLF's, depth performance will be dictated by the ground mineralisation in your local area.
As with any detector, it does take a while to learn what the Racer tones are telling you, especially on really junky locations - something I am still in the process of learning. It is a bit sparkier than the Deus and doesn't always require high levels of gain to achieve good depth, sometimes running the gain too high will highlight the iron a bit too much. With respect to recovery speed, it has already been proven to be competative with the Deus in 3 tone mode, with two tone VCO being good for relic sites when digging all non-ferrous targets. If I have any criticism, I would have preferred to see a multitone or at least 5 tone option for a greater spread on target tones. Guess I am just spoilt for choice on the Deus with regards to tone options, though keep in mind it is a much more expensive detector.
The S-shaped shaft took a little getting used to, it can be a bit nose heavy when using larger coils. The stock 7x11" and optional 5x10" coils are pretty light to swing, I have yet to use the 5" coil in anger, though I suspect the hockey puck will get a workout when my sites start becoming depleted of non or partly masked targets.
For the price point it offers a ton of features, the backlit screen is one of the best in the business, and it is an even more complete package with the addition of the new wireless headphones. I now run the wireless headphones all the time, as the protective cover for the rear battery compartment tends to muffle the external speaker audio.
Aside from the Nokta accessory coils, NEL and MARS MD produce a good range of aftermarket coils to cover all aspects of detecting. I also have the 13x10" Mars Tiger coil for greater coverage and some additional depth.
As with any detector, whether you will gel with the Racer 2 is something you will have to find out for yourself. Personally I really need a good chunk of time on it to become more proficient, something that doesn't happen overnight, or possibly even after several months of familiarisation.
This was the result from my last beach detect, 58 coins between the Racer and Deus, with the Racer set and ground balanced on beach mode. Some coins were near surface, whilst other were well beyond the 10" mark.
