pulse 8x or aquapulse

[wkola]

Im trying to figure out the best uderwater detector out there jw fisher says they have the best pulse 8x out there. but aquapulse says they have the best can anybody give me some insite at which one to get. Pulse 8x has a meter and tone. Aquapulse has tone only. which is better and why.
Thanks for any help pat

Pat,

Both those units are designed mainly for diving applications and do not have faster delays which is needed for shallow water detecting/sensitivity to smaller gold items. The slower delays on those machines are needed to compensate for the much larger volume of sea water when diving.

It all boils down to what sort of water detecting you have in mind, diving or shallow (less than 6 feet).

I wouldn't choose either of those units if you hunt in shallow water...they will struggle to find the smaller gold rings. If you plan to dive then both are supposedly good units.

Hope this helps,
Tony.

Thank you for the input I will be diving 6 ft and deeper.
They claim that you can use either on land or water is that true
Thanks Pat

Absolutely....any PI designed for water will work fine on land too, but a diving designed PI will not get you the best results for the reasons below.

The only critical area is where the minimum pulse DELAY (or REJECT) is set.

The Aquapulse has a minimum pulse delay of approximately 30uS. This setting is needed if you dive otherwise the volume of seawater would become one large signal to the detector. The flipside is that if you used this setting in shallower water or wet sand, then 30uS won't give you much sensitivity to the smaller nice gold rings. In this environment, a faster delay is needed to pick up these targets. The 30uS setting will be nice and quiet but will not pick up pulse decays of some rings (which dissipate very quickly)....the faster settings are needed to capture these targets. This is where other PI detectors (such as Eric Foster's line of machines) really come into there own on the wet sand and seawater to around 5-6 feet, although at those depths, the quickest delay neeeded is about 15uS. 10uS can be used on the wet sand and water to about knee deep.....as you get deeper, then the delay has to be retarded to allow for the increasing volume of seawater which the detector will see as one large target if the delays are too quick.
If I was interested in diving...6 feet deep and on, then I would use the Aquapulse, which interestingly, was designed by Eric some years ago.

Thanks for the response tony.

So is the aquapulse 1B better and more reliable than the pulse 8x.
Thanks Pat

Couldn't say which is better.....I've briefly used the Aquapulse that a local dealer provided me.

I like the design of the Aquapulse...very well made with a nice range of coils/probes and headphones that can be changed via highly regarded Ikelite connectors.

Don't know much about JW Fishers...they look a bit unwieldy and a meter display underwater may be ineffective when sand is stirred around or general visibility is poor.

Regards,
Tony.

Thanks for all your help I`m going to get the aquapulse.

Good luck with it

What items are you hoping to find ??

All the best,
Tony.
