On my 898si unit I have three main connection points for the unit,power ,antenna,gps ,I cant understand how such an expensive and great functional unit has such pathetic connector points for the unit .the brass female and male pins are so fine in diameter it doesn't take much to bend them when adapting or removing them from unit .i cant understand why they are so small ,it is a guaranteed flaw in the units.everyone cannot leave there unit connected in the rigs all the time ,meaning continuous removal of unit for safety . mine have been damaged and broke of .surly the unit can have better brass adaptors installed to make them more user friendly .that is one area lowrance has the bird covered big time, half lock adaptors with large pins for good connection and strength .I surely cant be the only one with this prob.i love the unit just frustrated with this continuous prob of broken or fractured pins cheers AL
