Sine wave

March 17, 2012/0 Comments/in Uncategorized /by Ewout Kozel

A sine wave or sinusoid is the name of a waveform that mathematically corresponds to the sine function [y(t) = A•sin(ωt + θ)]. A pure electrical sine wave does not produce harmonic frequencies.

I order "Rattler" headphones for my e-trac late one Tuesday evening. They shipped right away Wednesday morning. I received them Saturday USPS and hunted with them that afternoon. They are Awesome and so was the speed of shipping. They understand the hobby and what we need and want! I will shop here again!read more

I ordered a Garrett Ace 250 on a Saturday and the unit arrived on Wednesday, just 3 biz days. I didn't see the shipping info at USPS and was initially upset with the seller but it was NOT their fault but rather, for some reason, USPS didn't update the shipping info. The seller was kind and patient even after I was upset, wrongly, with them. I ordered the Ace 250 for a gift and checked it out before presenting it to the lucky recipient. I know this is a review of the seller but I wanted to leave an observation regarding the item purchased and my reason for my plans to purchase an Garrett AT Max from this seller, SERIOUS DETECTING on EBay, very soon. I tested it against my 1980's White's 6000 Di Pro Plus. The 6000 is a great unit and is very sensitive and it was very expensive for it's time. The Ace 250 weighs about 1/2 of what the 6000 weighs and not having to fiddle with ground balance was nice. Which as a little finicky, at times, on my 6000. I liked the tone differentiation between metal types very much on the Ace 250. Testing on a 2005 US Quarter, the 6000 would easily detect the target at 9.5 inches. The 250 was more like 6.5 inches. So, the depth edge goes to the 6000. However, the ease with which the Ace 250 operated and the much easier to hold/swing for long periods of time has helped me decide on a new unit for myself. After lots of youtube videos, online reviews and overall pleasure it has been to use the 250, albeit, for less than 30 minutes, I have decided my next purchase will be the Garrett AT Max and the place I plan to purchase this unit from is SERIOUS DETECTING. They are a first class group and have won my respect, repeat business and my future recommendations of their service. This was my first time dealing with SERIOUS DETECTING and unlike so many other vendors, this company really delivers.read more

If you are serious about metal detecting, the name is all you need. I have been doing business with this shop for several years and have never been let down. The pricing is fair, shipping reasonable, and they just plain have what you need. I recently ordered a replacement remote box mount for my 4 year old XP Deus. It arrived two days earlier than I expected and was perfect. No damage and was exactly what I needed. Check them out for all your Detecting needs. They won’t let you down!read more
