Yep, a great detector, the Sword. I have the one that Andy Sabisch used for his initial evaluation for Minelab. It has seen many changes: SunRay battery, WOT coil and today it has a 10" coil, the RNB EX3000 Li-Ion battery and a carbon fiber shaft and a new set of O-rings. The leaks around the control knob tubes were fixed with the Bondic UV Light glue. RTV, Aquaseal and others have all failed. I hope this UV glue is the Holy Grail, it sure looks like it will be.
The Sword battery pod was made from a piece of tube and an end cap glued together. The newer pods are a one piece molded unit. They had square mounting wings not the slated ones of today's Excaliburs. Long ago I cut the square corners off so the pod would fit the newer control housings. A model maker were I retired from had some solvent that sealed the leaks at the pod's end which is still holding some 20 years later. I wish I knew what the solvent's name was. I saw the TANKED crew making a fish tank and they use the same solvent. It only came in a gallon can as I remember. Something to look for....
