Brilliant bits of kit, light and versatile when compared to the old 12v leisure battery powered aerators, they charge relatively quickly and the battery lasts a decent amount of time. We not only use them when transporting fish health samples in our 4x4 vehicles, but also for aerating bins on our survey boats when carrying out electric fishing surveys.

Service and Communication Absolutely fantastic, great to deal with, very professional on the phone The product exactly as described, perfect

I've been taking oxygen readings twice a day for over a decade. The RDO Probe with Wireless Troll is the best oxygen meter I have ever used, it's the meter of choice for daily use at the fishery and my trusty old galvanic meter is now gathering dust. Months of testing proved the RDO probe was accurate against my galvanic meters. No calibration makes taking readings quicker. So easy to operate anyone can use one with no training. Not having to renovate the probe is a bonus. Love it!
