I pitched a royal fit to get a spare battery with my AQ Ltd, and it helped get an official retail price formulated, which I gladly paid. Fisher Impulse AQ Limited spare NiMH battery, part# PI-BATPK-NIMH $199.00

Any ideas as to how the extra battery can be safely carried so as not to corrupt any of its components while hunting in total submersion in salt water?

Well burped dry bag? I know for people a long way from the rig that may be an issue. For me after 4 hours I’ll be fine with a hike back to the car for lunch and a restroom break, swap batteries. I’ll be keeping canned air and Q-tips in the car to properly clean the connections before swapping the battery. For now at least I’ll treat the battery connections with kid gloves until I get a better feel for the detector in actual longer term use.

Sounds like a good way to go. Being on the cautious side... I'll use two!

If you already have an Impulse AQ, don't you already have those measurements? :huh:

      Approximately  3 hour hunt (one battery), about 2 hours in the water in the Gulf. Water was almost flat with a slight current, bottom was rippled. This particular beach doesn't get many tourists and is somewhat out of the way, I didn't expect a lot of targets.
      Since I still have loads to learn on the machine, I didn't spend a whole lot of time with any specific setting as I was trying to see what adjustments did what. Hunted in all metal the entire hunt.  I found you really need to hunt slow to avoid any rising threshold due to swinging into deeper water. Sensitivity adjustments and delay adjustments helped. The machine was more than useable in the water with the exception of the coil connector when it enters/exits the water. Odd thing on that was I thought I was shallow enough but the connector sticks out a good ways.....
      The tent stakes, sinker, and bottle caps were from the wet sand. The few other targets were from the water waist to chest deep. The dime seemed to be the deepest target at about 3 scoops deep give or take. There was no mistaking the ring as a target, it wasn't a whisper at all.....got it with the second scoop.
      Pinpointing the target prior to digging was easier with the 12" coil then I had thought it would be.
      Balance on this machine is really good for wet/dry hunting, however, it did take a few adjustments to my typical hunting style to have good coil control in the water, it does show you how "bad" your normal coil control may be....
      You sure don't have to worry about when the battery is getting low, it lets you know when it is time to change batteries or go home!
      All in all, I'm liking this machine so far....

      Got a chance to try the AQ on the wet slopes at one of my beaches. I spent most of the day waiting for a low tide so I could see how the AQ performed for me. This beach is generally protected, so the beach does not get ripped up very often from storms. The first part of the day was using my GPX for the dry sand. Late afternoon I spent 2 ¾ hours on the wet slope with the AQ. I ran mute exclusively with 7.5us. It ran very stable with almost no end of sweep falsing. Really nice and smooth. I am still learning, so I dug everything I heard (and even a couple of nulls) which ended up being a quarter and a toy car. The hair pins and long thin wires all gave a double beep, I will be passing on digging them from now on. I will probably live with digging the bottle caps as there are not as many on the wet slopes as there are on the dry sand. I did find 2 rings and was hoping for gold but stainless 316 and aluminum is all I could muster up. They did come in very strong and were in the 10-12” range. All in all, I am happy with the performance of the AQ and I am sure when I get some hours under my belt, I will be more confident in what to dig. I rarely give up on digging a target once I start, but I had to leave a nice deep small target. The water was filling up the hole and the sides caved in so many times that I gave up on it. This area of the beach has a layer of fine sand followed by a layer or small pebble and shell. The next layer has larger rocks locked together tightly. A small target was located somewhere in that last layer. Using the edge of the coil vertically as a pin pointer on the AQ works excellent. What does not work at all is Garrett's pin pointer in water. Even balancing it to the water does not help. I think if I had a better pin pointer, I would have located that target. Also, I am really liking the ease of using the AQ. It does not take you long to get used to how it works or how it sounds. I think it will work well for my type of beach hunting.

      This could happen to you!!
      Long slow romantic walk on the beach this morning. Almost 3 hours in it's time to change the battery. I take the battery off the detector to make the swap and look at it and holy cow the thing is bulbous!
      I suspect this is what happens when you don't practice safe charging.
       
      I was just thinking about the recent threads on the beautiful batteries OBN is making and thinking I don't need to get one, I've got two perfectly good batteries. I'm going to rethink that. HELP OBN!

      This is my "field expedient" really low budget Connector Protector. My original plan was to simple add a piece of 3/4" pvc to the end of the shaft to protect that frail looking little connector in case a fall. That done I thought if I add a 90* elbow and a "tee" them it sorta kinda protects the battery also.
      If you decide to try this, the only little trick is the 3/4" pvc doesn't quite fit over the end of the detector shaft. You need to make sure the black end cap that has the connector is flush (may require a tiny bit of sanding). you need to heat your piece of 3/4" pvc with a heat gun and when it is soft slip it over the end and let it cool. It will be a very tight slip fit. You are good to go.
       
      Up next my pregnant battery.
