Ultrasonic Leak Detectors

[Teuchtar]

Does anybody have experience using the CDL Leak Detection tool, or the VOScope unit to detect leaks in mainlines ?
They both use ultrasonic technology. The VOscope model can be had for about $116 on Amazon. They talk a lot about detecting vacuum leaks around car engines, but no reference is cited for maple mainline use.
Seems to me that any tool that will help find more leaks and faster than my old deaf ears is maybe worth the selling price of 3 gallons.

I have been using a vacuum leak detector for years. The one I have is made by Inficon. Mine will not pick up a leak at a distance as CDL advertises. It works great for the very little leaks that you would miss. They will give you false readings when walking in dry leaves or the wind blows across it just right but you just make another pass to double check. Works great right around the pump where noise would make it impossible to hear a leak. Hope this helps. Would love to see a demo on the CDL one. If it worked as described I would buy one. My question I have would it really detect a leak at the distance they advertise.

had a demo at Verona on the CDL unit. Very impressive, all other noise was blocked out but the air leaking around the vac gauge they had set up. Think CDL was around 400

Yes. Not sure where I got it or how much I paid. Got it about 10 years ago. Think I may have gotten it on Ebay.

Thanks Usmapleman. I just paid $150 shipped with accessory kit on eBay

So I assume you guys use this walking up and down mainlines? How close do you have to be for it to detect leaks? Seems it may have a huge benfits at saddles

The one I use does not detect from a great distance. Usually a couple of feet. I find what lines are leaking by watching the sap movement in the line. If it shows a leak I walk it and hold the detector near the line and it sounds when you pass a leak. I find it works good on main lines. As I walk from saddle to saddle I just hold it near line and if there is a leak it sounds off. I have a huge bear problem and they often times bite the line and you may not see it or hear it (to much shooting and heavy equipment operation without hearing protection) but if it beeps you check closer. Will give false readings if you walk in dry leaves but you just stop and pass it over the spot a second time. Works great around you pump where noise would make it impossible to hear. CDL claims theirs works at over 25'. That I would have to see first hand before I paid that much.

Wiam, did you get it yet? Is it what you thought it would be? What is the info to get the same?
Thanks,

It was on eBay. Only one that seller had. I used it to find a slow leak in a tire. I guess I will know more in a couple months.
