Leak detection, What would you use?

[The Doctor]

I recommend a D-Tek Select. They have a tip upgrade so as not to catch so much big blu(I heard). I found this dandy little leak (pictured below)easily with the D-Tek, and shifting it into low sens. took me right to the bridge and dropped me off.
Here are a couple of pics for your kind review.
I must say that for whatever reason this little leak repair was whipping me bad until I put brazing flux on it. All in a day's work I guess. That's why they make nitrogen.

I have had the H-10 for some years now and it is very reliable. Don't remember getting false readings from it.

Now the D-Tek is a bump detector. Try wiggling it thru pipes and such and bump into something.....it will alarm..

"All I keep hearing from you guys is how great this H-10 is. I'm considering purchasing one now. What can I expect to spend? What's the best place to find one? I understand there's several manufacturers, so which particular brand is the best?"

Whenever I have a small leak(s) in the Evaporator, it always seems like I have a lot of growth in the drain pan. The bacteria feeds off the oil and water. If it's a large leak with a lot of oil, you just get an oil and water mixture. A place that I've had odd ball leaks is in the bullet style pressure controls, with the refrigerant leaking out of the wires. Also kids bubble soap is great for finding very small leaks.

I have found that small leaks in the a-coils leave virtually no oil. Removing the coil and isolating it with a nitro test and bubbles will do the trick. These are the type of leaks where they take a pound or so every year or two.
Big blue seems to be better at finding very small leaks rather than bigger ones. It creates a big cluster of bubbles over time with a tiny leak, but a thinner mixture of soap seems to work better at the larger leaks.

With the higher pressure of 410A it will be interesting to see how these coils hold up.
