I have a Subal ND3 and am considering adding a leak detector.
I contacted Backscatter and Russ suggested their manual AirLock model. He said that given that it contains no electronics, there is little to go wrong. I have always received good information from Backscatter and respect their opinion. Their AirLock does seem rather large and bulky.
Reviewing Wetpixel, there have been good things written about Leak Sentinel. I contacted the company and they replied within hours and recommended the V5 XB. It seems more compact and has received generally favorable recommendations.
Any other products to consider?
Thoughts? Suggestions? Recommendations?
