So very happy! I've purchased my bat detectors from Martin and they've always arrived promptly, well packaged and at a reasonable price. He’s always very helpful with questions about my field cameras. The Poland trips are an additional bonus. I went with Martin and Cheryl for an autumn of mushrooms, beavers and rutting deer. The trees were turning and the mountains were peaceful. I'd have gone with them for Poland in the spring, except covid got in the way. And I am looking forward to Poland in May; the birds returning, flowers growing, animals at their best in the spring, once covid restrictions are fully lifted. I recommend the Poland trips! (Martin has a good temperament and Caleb has mis-interpreted his sometimes off-the-wall sense of humour.)
