Fresh water lake ,Black sand,Lack of depth..Any suggestions?

[NiagracountyNY]

I've been hitting a beach on Lake Erie the last couple days.I noticed i wasn't getting many deep targets ,so i buried a few coins to test it out.Bout 6 inches in the dry sand( Not sure on water targets).Well i tried every mode,and tried changing to every combo of settings i think are possible.Barely any improvement.I noticed a ton of black sand on the water line.Anyone have any suggestions I might try to correct this.?I didn't try my cf77 ,Maybe the induction VLF will deal with it better?Any help would be great.THX

Never heard of an induction VLF, but a pulse induction would do the trick.

Well i cant find the link to where is says the Makro cf77 is induction vlf...I think its induction balance,just like Nokta's velox 1).Heres the link to the specs,shows induction balance http://noktadetectors.com/specifications_velox-one-metal-detector.asp the cf77 and velox 1 were made by the same team of eng. Cf77 released after adressing a few issues and adding more depth it seems.So only PI machines deal with this situation well?.....Excal 2 time? .

Black sand will give any VLF detector fits and as Nolan said, the cure is a PI detector. The best you can hope for with the CTX is to manually ground balance.

I did that and manually picked a noise cancle channel which helped a tad..Gotta have a diffrent detector for every place you go it seems .Be nice if one machine switched between PI and VLF...Come on Engineers!

One machine for both..... never thought of that but it would just about cover all bases. Imagine the weight and price...ugh
