These modification significantly improve the operational longevity of these versions. They are not hard to do and are inexpensive. Although not advanced as the latest units. This one is competitive and useful at depths of up to about 75 ft. It has been a great learning experience working here at HQ and hope to have my second one(2.6x) built soon.
If you have one of these versions and require assistance, please contact me! I’d love to help.
