PulseDive 8” Coil Review


Recommended Posts

Hey guys!

I was lucky enough to test one of the first sample 8” coil units For the  Pulse Dive and what I found was very pleasing! 

From the beginning I was hoping that Nokta|Makro would make a larger coil for the PulseDive so I was very excited when I heard from Dilek that they were doing exactly that!   I was given an 8” coil to test and although I admit that it was essentially a finished product already!

My first concern was that the larger coil would be too easy to twist off accidentally due to being larger and having more leverage but upon receiving I found they had already thought of this and actually provide the coil with a harder gasket/o-ring so the friction is high making it harder to twist off and very unlikely to come off underwater! 😃

My next concern was that the coil would be overly sensitive causing it to false excessively in mineralised areas or just from salt water but once again my concerns had already been addressed and the machine was stable in salt water however it is important to note that the machine must be turned on or retuned in the salt water because turning it on in air and entering salt water can cause it to false but of course this is a non-issue just important to note for new players.

The depth on this coil in air tests is consistently in the range of 30% more than the standard coil and from the hours I’ve put on it I’d have to say this is reflected underwater also.  The coverage is also greater so at a guess I’d have to say the 8” coil scans double the volume of sand in a single sweep than the smaller coil does 👌

Pinpointing on the larger coil is more difficult and I would recommend for low/no visibility conditions using the smaller coil for the speed of recovery however with enough practice and the right techniques it is certainly possibly to hone in your pinpointing skills with this coil.  One trick I’ve learnt and seen used with other detectors is to turn the coil on its edge once the target is close to narrow down your search even further and it’s definitely applicable to the 8” coil.

I’ve had some questions about battery life with the larger coil and I haven’t noticed a difference so I’m not sure if there really is a difference in current draw from this coil or not but I can still get 8 hours from it which Is enough for one day! 😂

Overall the coil is more effected by mineralisation and EMI which is standard for larger coils and pinpointing is a bit more difficult HOWEVER the depth and coverage in underwater scenarios is comparable to other water detectors costing literally 10X what the PulseDive costs.

I have now switched to using this detector/coil combo almost exclusively over my other water detectors (whites Dualfield and Garrett Seahunter mk2) mainly for convenience, low/no maintenance, no cables or knobs to fail and no need to wear headphones however I will still use these machines where there are a lot of hot rocks so I can remove them or reduce their signal by adding pulse delay 👌

Cheers, Ed

Thanks Steve!

I think I mentioned the most important points but anyone feel free to ask questions. I’ve got a few hours on it now

I also did an air test a couple of months ago and uploaded to YouTube for those interested.
