if we are in this thread is about "beach comb" (rake to find gold chains), then I'm doing them (2 years) and sell (1 year).
do 2 types of "beach comb": 1) the distance between the teeth of 87mm (3.4 ")" Standard Version 8 teeth.
2) distance between the teeth of 56mm (2.2 ") version of the "meanie" 12 teeth for clean places
Height of teeth 110mm, length 600mm ,the weight 2-2,5 kg (also can heavier rake soil or lead, this is a special cavity).
fully collapsible stainless construction, built using the screwdriver for 5 minutes.
I usually apply them there where they found the crosses, icons, zodiac signs .... a chain device is not found here, in this case need beach rake.
I also check at the request or hint where friends were lost gold chains.
Although many hunters who have purchased my "beach comb" just scoured the coastal trough after the first autumn storms.
at locations with high salinity is the only way to catch a thin gold chain.
Here is a topic about the Russian site, if anyone interested
