This was our second bat survey using Arbtech. Craig and his team were very professional. They were friendly, polite, enthusiastic, efficient, organised and knowledgable. They were happy to share their specialist knowledge with us and, because we are interested in wildlife and bats Craig encouraged us to use one of his bat detectors. Craig asked all about our building plans and was happy to listen and to answer our questions and to give us his expert advice when asked. During the survey, Craig explained and demonstrated how we could identify the different species of bats as we watched them flying around our garden. Craig managed his team well and produced and emailed the report to us within a few days. Excellent and highly recommended.
