Yes. While for work we only buy Bacharach, for your application I'd try one of the cheap
ones. One problem you may have is the leak could be in the tube and tube heat exchanger
so you won't find it unless you check the discharge thru-hull. I know this from hours and hours of searching for one on Palarran.
Soap bubbles work. So does very careful observation. A small amount of oil
will escape with the refrigerant and if you really look at all the joints, it is usually apparent. We have also just started to use infrared cameras to find leaks
. I personally haven't but my service
manager says it works very well. Those cameras have tons of other uses so it may be worth investigating.
On Palarran I have a jug of R-22 and R-404, gauges, small vac pump, mapp gas torch, braising rod, leak detector, and various other refrigeration tools and parts
. I went way overboard
(and regret) when I bought a spare Seafrost condensing unit but figured it would be nearly impossible to get one in the Med. IMO, it's one of the hardest things to get repaired while cruising.
