Anyone know where to acquire a dwyer rma-22 online? Just did a google search and nothing came up as far as retail goes. Do I need any accessories to test?
I just picked up a dwyer rmb-53 off ebay for $30. In another thread it was suggested to stick with the RMB or RMC (most expensive) models as they are more reliable. The RMA series I guess causes enough back preasure on skimmers to mess the reading up with the RMC causing the least amount of back preasure. I believe it was in a Warner Marine K2 thread.
