Too easy to fit. It just works!
Fitting this product was simplicity itself. In fact the job was so easy it actually offered no sense of fulfillment! The sensor worked first time without adjustment. Great value for money and good build quality.

Battery details and sender radius wide
Quick delivery, exactly as requested. Straight swap with ancient Watchman(old design with copper battery tube and number display). Drill holes and hole diameter same as old, perhaps needs a little more peripheral clearance around sender unit to allow it to rotate while screwing it down onto the base. I had to cut off the small projecting plastic tube from the side to allow rotation. It is a blind end tube which looks redundant if no other parts are connected. Link instructions good, worked first time. Battery is installed already, but I had removed the cover to discover that, voiding the warranty. INSTRUCTIONS SHOUJD MAKE THAT CLEAR! Otherwise works fine

Easy replacement, same dipswitch settings, but you might just need a new battery.
My last one died after 25 years - I changed the battery in the transmitter but then next time it stopped it was full of water. If you change the battery be sure to seal with silicone. Anyway, the new unit quick and easy to replace, but be sure to get it vertical.
