pool water continuity

[NC.Tech]

I was recently asked to check the pool bonding at a job our company had done last summer to see if there were any hazards present before the upcoming pool/swimming season. I researched the topic and paid close attention to the Mike Holt videos on how to check for proper bonding, continuity and N-E voltage. I built a similar rig to what he used and began my inspection. I found a few issues to correct but there was one thing I didn't expect and can't explain.
The complex has multiple swim/activity areas: a lazy river, lap pool with slide, kiddie pool and water spout area. I was able to get an audible continuity tone at many points of inspection: actual water in pool, hand rails, ladders, lights, spouts and drains. What has me stumped is that even though I got the same numerical value(0.3) of the water surface in the lazy river and lap pool: I did not get an audible tone at the water surface in the lazy river but got one at the water surface in the lap pool. The water surface of the kiddie pool even gave an audible tone at a value of 1.5. Is it even a concern being that they both have the same numerical value? The value indicates they are both equally electrically continuous so why no tone?

You said you watched Mike Holt's video on checking pool bonding. I would be more concerned that I got the same, or close, voltage readings on all the areas to be checked. I wouldn't worry so much about the tone if everything else checks out. Maybe try a different meter.

Verify all required GCFI with in twenty feet of the swimming pool

Most common bonding issue someone did not reconnect the bond to the water pump after putting it back into service for the summer months
